Examining Workforce Investment Act Programmatic Outcomes
by: Sylvia D. Jones, M.A., Statistical and Research Analyst
Workforce Investment Act participation appears to be very effective in improving the economic lives of participants. For example, 65 percent of Dislocated Workers and 61 percent of Adults experienced at least one positive outcome from participation; many of those experience more than one positive outcome.
The U.S. Department of Labor, Employment and Training
Administration (ETA) currently uses employment, job retention, and earnings increase
performance measures for programs funded by ETA (U.S. Department of
Labor, ETA, 2003). Section 171 of the 1998 Workforce Investment Act (WIA) requires
the Secretary of Labor to prepare a five-year research plan for pilot, demonstration,
research, evaluation, multi-state, and multi-service initiatives every two years. ETA’s
research plan provides for the evaluation of existing programs but it also covers
applied research, including labor market research. Section 171 requires the continuing
evaluation of programs and activities using appropriate methodologies and research
designs, especially experimental research designs (U.S. Government
Accounting Office, 2004). Unfortunately, experimental research is expensive, time
consuming, and often raises legal and ethical issues. This paper addresses the current
performance measures used by ETA and provides alternative measures that could improve
program outcomes.
A basic limitation with the current ETA performance measurement strategy is the
failure to measure outcomes in the context of the surrounding labor market. Without
the labor market context, neither the state nor ETA can determine whether changes in
wages and retention are effects of WIA participation or simply a reflection of the
local economy.
ETA’s current evaluation strategy also uses a limited number of outcome measures,
preventing a thorough understanding of program outcomes. Research emphasis has been
placed on finding new ways to evaluate the current outcomes without determining
whether or not those outcomes represent program success. While performance measures
can drive program development and management, it is not clear that federally required
measures capture relevant information pertinent to employers, workers, or program
managers.
To answer a few questions about ETA-prescribed WIA participant performance measures
in Wyoming, this paper shows WIA training participants in the context of the Wyoming
labor market. This context provides a framework for evaluating labor market outcomes.
Furthermore, new outcome measures are investigated as potential enhancements to the
strategy already in place.
Literature Review
Several studies report wage and employment increases for disadvantaged adults
immediately after completion of an employment and training program. Bloom, et al.
(1997) showed significant monthly earnings increases for those
who participated in a training program when compared to a control group. Positive
effects were greater for those who received on-the-job training, job search assistance,
or technical/occupational training.
Other findings show disadvantaged adult women participants are unemployed for shorter
periods of time following training than are other participants (
Eberwein, Ham, & LaLonde, 1997). LaLonde (1995) and
Couch (1992) found disadvantaged adult women benefited from
training services more so than youth or adult men. Finn and Willoughby (
1996) demonstrated that being unemployed for fifteen weeks or more prior to Job
Training Partnership Act (JTPA) enrollment negatively influenced the odds of being
employed upon completion of a training program. Receiving training from a current
employer rather than a training provider unfamiliar to the trainee positively influenced
employment. Similar findings were reported by Hollenbeck and Anderson (
1993) who found that job-specific training programs improved males’ employment rate
and increased females’ wages.
Findings from research on the Wyoming WIA participants were not similar to studies
which showed positive economic outcomes for WIA adults. Harris (
2002), using a quasi-experimental design and administrative records, found no
difference between WIA participants and the control group in the year following
training.
Few studies have been conducted on the economic outcomes of Dislocated Workers who
complete a WIA (or JTPA) training program. Some evidence suggests the effects are
insignificant on both wages and employment rates, even when other group differences
were controlled for (Leigh, 1997; Kodrzycki,
1996). Alternatively, Jacobson, LaLonde, and Sullivan (1999)
found that Dislocated Workers increased their annual earnings by $20-24 per completed
credit hour in community college classes (in U.S. Department of
Labor, 2001). Greater earnings were seen for courses completed in health related
fields, technical and vocational fields, or math and science fields. Other studies
report a positive and significant impact on earnings after training (
Benus & Byrnes, 1993; Jacobson, LaLonde, & Sullivan,
1994), but the findings were not generalizable.
Examining only short-term outcome measures, notably wage progression, fails to
show the entire picture of WIA outcomes. “The short-run performance measures
that are used in its [value added net of social cost] place are either uncorrelated
with or negatively correlated with net value added, especially in the long run”
(Heckerman, Heinrich, & Smith, 1997). For example,
research conducted on Wyoming community college graduates showed wages did not
rise above a comparison group until 9 to 18 months after program completion
(Gallagher, 2001). Without longitudinal analysis as
a measure, community college education would appear ineffective in increasing
graduates’ wages. In fact, it simply takes time for the graduates to stabilize
in the labor market.
As evident from the data, disadvantaged adults, especially women, tend to fare
reasonably well economically compared to control groups in the first year after
training. Unfortunately, the long-term consequences are much more dismal.
The United States General Accounting Office (1996)
released a report to congressional requesters on the efficacy of JTPA. The
report describes a study performed in response to congressional concern about
the long-term impact of job training programs. The findings demonstrated that
the positive effects of JTPA during the 30 months following training are not
permanent. Adult men earned significantly higher wages than the control group
one, two, and three years after training, but the effect dissipated by the
fourth year. Adult women earned significantly higher wages than the control
group every year after training until the fifth year. Both male and female
youths never achieved significantly higher wages than the control group in
the five years subsequent to training. If the program has no long-term impact
on participants and questionable effect in the short term, is the program
attaining its goals?
Both WIA and the Personal Responsibility and Work Opportunity Reconciliation
Act (PRWORA) of 1996 promote rapid entry into employment. Under WIA, only
individuals unable to obtain employment through less intrusive core or intensive
services are eligible for job training, meaning that all efforts are made to
find an individual employment before the individual qualifies for training.
Additionally, WIA participants are required to be economically disadvantaged
(U.S. Department of Labor, 2001). With the passage of
PRWORA, time-limited benefits and significant work requirements replaced cash
benefit entitlements. Instead of receiving government assistance in the form
of cash, individuals are required to work. As a result of these policy changes,
individuals with few skills or work experience are being placed into entry-level,
low-paying jobs because the emphasis is on employment, not employment that pays a
living wage. In addition, the monthly income of many families falls after finding
work because they do not make high enough wages to replace the lost government
subsidies (Friedlander & Hamilton, 1996). Despite the
strong economy and the substantial decline in welfare rolls during the latter
half of the 1990s, the extent to which low-skill workers and former welfare
recipients are able to retain their jobs and advance in them is unknown
(U.S. Department of Labor, 2001).
Past evaluations of employment and training programs have demonstrated that
many individuals who successfully obtain employment often face additional
barriers to retain employment. Recently, more focus has been placed on training
that assists individuals in remaining employed (U.S. Department of Labor, 2001).
Finding a job is of limited value if the person is unable to keep it. Research
on the effectiveness of existing retention strategies is limited and needs to
be expanded. This is particularly important due to a strong relationship
between employment tenure and earnings, regardless of the type of employment
(Glover, 2003).
The logical next question is why continue to fund a program that fails to
achieve federal mandated goals that were developed in the absence of empirical
statistical knowledge? The simplest answer is that the outcome measures are not
capable of reflecting the advantages gained by program participants. Therefore,
the research should focus on identifying how WIA participation really affects
program participants and how those effects can be quantified rather than how
we think WIA should affect participants. When that is determined, the empirical
data can drive ways to enhance the program to maximize the advantages.
A starting place for examining program effects is industry of employment.
Industry is strongly related to income. Those who work in Mining or Transportation,
Communications, & Public Utilities (TCPU) typically earn significantly more
than those who work in Retail Trade. In addition, retention is usually higher
in those industries than in the lower-paying industries (Glover, 2003;
Mishel, Bernstein, & Schmitt, 1999). Bartik
(1997) showed welfare recipients were more successful
for longer periods of time when they were placed in health care; educational
services; Finance, Insurance & Real Estate (FIRE); and durable goods
manufacturing. Unfortunately, the highest demand for WIA trained workers in
Wyoming and the U.S. is in Retail Trade.
Another area to investigate is turnover. Many individuals who register for
WIA services have difficulty maintaining employment, especially employment
with a single employer. Turnover is associated with lower wages (
Jones, 2001). If WIA program completers learn job skills that enhance their
ability to maintain employment with one employer, their wages will likely
increase as their tenure increases. While lowered turnover rates may not
result in immediate wage increases, they generally reflect improved employability
of the individual.
Another possibility for outcome measurement is the number of Unemployment
Insurance (UI) claims filed. Currently, the outcome measures note whether
or not a participant was employed in a quarter but there is no indication
of how long they remained employed or how attached they were to their employer.
This study sought to evaluate the federally required outcomes of WIA
participants in Wyoming (earnings after training) for eight quarters
after program completion. A quasi-experimental design was employed using
administrative records in the absence of random selection. It was expected
that WIA would have a positive effect on wages in that wages for the WIA
group would increase after training. Theoretically relevant variables were
statistically controlled so that a more accurate test could be conducted
between the WIA participant group and the Comparison group. Statistical
controls provide for the mathematical removal or control of competing
additional theoretical explanations of outcomes. Such controls are introduced
after the fact as opposed to experimental designs that insure comparison and
experimental group equivalence through pre-treatment random assignment.
In addition, we suggested the addition of new outcome measures: turnover rate,
industry of employment, employment rate, and UI claims filed. We also created a
combined success variable based on the other suggested outcome measures.
Methods
A broader evaluation of current performance measures was conducted by putting
Wyoming WIA training participants in the context of the Wyoming labor market.
New outcome measures are investigated as potential enhancements to the strategy
already in place.
The study group included Wyoming WIA participants for the Program Year 2001 and
224,217 individuals selected from the Wyoming UI Wage Records file. There were
568 individuals who participated and exited WIA training during the program year,
including 217 Adults, 110 Dislocated Workers, and 241 in Youth programs. The Youth
groups were removed from the analyses because their outcome measures differ
significantly from Adults and Dislocated Workers. The WIA participant file was
combined with Wage Records in order to obtain wage and employment information.
Turnover, employment industry, UI claims rate, and success were investigated.
The average participant age was 36.1 for Adults and 39.4 for Dislocated Workers (see
Table 1). The mean age of individuals in the Comparison
group was slightly higher at 40.2. Gender was unknown for 5 (1.5%) of the
participants, 185 (56.6%) were men, and 137 (41.9%) were women.
The Comparison group was defined as individuals who had wages in Wyoming during
Program Year 2001, were residents of the state (Jones, 2002),
and were not participants of WIA in Program Year 2001. The restrictions narrowed
the group to approximately 70 percent of all who worked in Wyoming during that
time period. All eligible individuals in Wage Records were randomly assigned a
termination quarter from the third quarter of 2000 (2000Q3) to 2001Q2. Total
wages were then computed for the six quarters prior and eight quarters after
the termination quarter. Table 2 shows the means and
standard deviations of wages by participation status both four and six quarters
prior to the termination quarter.
Demographics for the Comparison group were taken from the Wyoming Department
of Transportation (DOT) Driver’s License file. Wage Records were merged with
the DOT file using social security number (SSN) as the matching variable.
There were 106,779 (47.6%) women and 117,438 (52.4%) men.
Turnover was defined as the number of exits in employment divided by the number
of jobs worked during the defined time period (Glover,
2002). If an individual exited all jobs worked, the turnover rate would be 1.0.
Table 3 shows the means and standard deviations of the
turnover rates by participation status before and after program exit.
We defined employment industry using the North American Industry Classification
System (NAICS, 2004) code of the primary employer in each
quarter. Most previous studies used the Standard Industrial Classification (SIC)
system to identify industries, however, since then all states have adopted NAICS.
Primary employer is defined as the employer that paid the individual the largest
proportion of wages in a quarter, regardless of the number of employers. For
purposes of our study, living-wage industries are defined as those which pay,
on average, wages higher than 130 percent of the federal poverty guideline for
a family of four (Harris, 2003). The UI claims rate
reflects the number of participants who filed a UI claim at any time during
a quarter, not those who actually received UI benefits.
The success measure was a two-category measure that was assigned a value of
one to reflect a success. Individuals received a success rating if they met
any of the following criteria:
They gained post-program employment in an industry that typically pays a living-wage to employees (Harris, 2003; see Figures 3 and 4).
Results
Earnings
Research on WIA participant outcomes, with the exception of Harris
(2002), demonstrated positive earnings change after
training. For this reason it was expected that earnings of WIA participants
would increase after the termination quarter. The data partially supported
the hypothesis. As seen in Figure 1 and Table 4,
earnings of WIA adults and the Comparison group increased during the study
period. Dislocated Workers had no significant change.
When regression analysis was applied to test for group differences in
performance, statistically there was no significant difference in wages
based on WIA participation. Thus, WIA participants do not experience
additional wage progression beyond what the Comparison group also
experienced. A possible explanation is that Wyoming’s relatively strong
economy during this time period could have been driving the increase in
wages. The controlled variables all significantly influenced post-training
wages eight quarters after program termination (see
Table 5). The corrected model accounted for approximately one-third
of the variance associated with wages after training (R2 = .31).
Turnover
It was hypothesized that the turnover rate would decline for all groups
except the Comparison group after program termination. The data
supported the hypothesis (see Table 6). The
rates for both WIA Adults and Dislocated Workers significantly differed
between the two time periods, while the rate for the Comparison group
did not (see Figure 2).
When the regression model was applied (see Table 7),
neither Adults nor Dislocated Workers had a significantly different
turnover rate than the Comparison group when all other variables were
controlled for. The other variables all significantly predicted turnover
eight quarters after program termination.
Industry
Figure 3 shows the percentage of Adults
employed in living-wage industries before and after program exit.
Six quarters before program termination, 43.8 percent were not
employed in a Wyoming UI covered job, 39.6 percent were employed in
low-paying industries, and 16.6 percent were employed in living-wage
industries. Eight quarters after exit, 37.3 percent were not employed
by a UI covered job, 29.5 percent were in low-paying industries, and
the remaining 33.2 percent were in living-wage industries.
Table 8 shows the detailed change by industry.
Figure 4 shows the same breakdown for Dislocated
Workers. Before exit, 21.8 percent were not found in UI covered jobs,
41.8 percent were in low-paying industries, and 36.4 percent were in
living-wage industries. After program termination the percentages were
similar (37.3% were in low-paying industries, 34.5% were in living-wage
industries, and 28.2% were not found).
UI Claims Rate
As seen in Figure 5 and
Table 9, 3.2 percent of Adult WIA participants and 3.6 percent
of Dislocated Workers filed a UI claim six quarters before program
exit. This compares to only 0.5 percent of the Comparison group.
One quarter before exit, 8.8 percent of Adult participants and
15.5 percent of Dislocated Workers filed claims. At four and eight
quarters after exit, the Adult percentage had fallen to 3.7 percent
and 3.2 percent respectively. The Dislocated Workers percentage was
steady at 2.7 percent for both four and eight quarters after exit.
Employment Rate
Figure 6 and Table 10
show the number and percentage of individuals who were employed in
Wyoming before and after WIA participation. Six quarters before exit,
20 percent fewer Adult participants were employed than Comparison
group members. By eight quarters after exit, only 8 percent fewer
Adult participants were employed.
In contrast, the percentage of employed Dislocated Workers six
quarters before program exit was higher than the percentage of
employed Comparison group members. At eight quarters after exit,
Dislocated Workers were still employed more often than Comparison
group members, but the difference was only 1.2 percent.
Success
Table 11 shows the number and percentage of
WIA participants who experienced a positive outcome after program
completion. Over 60 percent either enrolled in a community college,
increased their earnings more than the average for Wyoming workers,
decreased their turnover rate, or obtained employment in an industry
that pays a living-wage. Many of the participants had more than one
positive outcome.
Discussion / Suggested Measures for ETA Outcomes
Study findings were mixed. Other studies which showed short-term
earnings gains were replicated because wages of both WIA program
segments increased after termination from the program. However,
their wages did not increase more than the statistical control
group.
While WIA participants initially showed a rather large increase in
earnings after program termination (see Figure 1);
those high earnings started to decline after the second quarter.
This could occur if participants stayed with their On-the-Job
Training employer for two quarters after program termination and
then needed to look for new employment, or if participants faced
retention barriers, such as childcare issues. Contrary to expectations,
changes in turnover rates cannot be predicted by WIA participation either,
even though turnover does significantly decrease after program exit for
both participant groups used in the study (see Figure 2).
The industry measure revealed interesting results. The industrial
distribution of Adult participants changed considerably after training
(see Figure 3). The percentage of individuals
employed in low-paying industries decreased. Alternatively, employment
in living-wage industries increased. The implications of this are very
positive. WIA participation for Adults appears to result in a shift
from no or low-paying employment to employment in higher-paying industries.
Dislocated Workers did not fare as well as Adult participants in the
industry measure. More Dislocated Workers were employed six quarters
before program termination than eight quarters post-program (see
Figure 4). Employment in living-wage industries
declined. However, employment in low-paying industries also declined.
It is possible that Dislocated Workers are leaving the state for
employment elsewhere, becoming employed in non-UI covered jobs, or
becoming self-employed. Enrollment in a community college or university
without concurrently working a UI covered job would also remove them
from Wage Records. Outside influences likely affect Dislocated Workers’
outcomes. For instance, Dislocated Workers tend to be firmly established
in a job before they become eligible for the WIA program. After program
completion they are encouraged to find employment in an area in which
they have no experience. They face competition from applicants with
more relevant experience for jobs that often pay less than what they
originally earned. Frustration with these situations could lead to
discouragement and an eventual withdrawal from the labor market. This
hypothesis could be tested using longitudinal and inter-state data.
The proportion of Adults who filed for UI benefits remained fairly
constant before and after program exit (see Figure 5).
However, the rate for Dislocated Workers dropped rather sharply meaning
they filed for UI benefits less often post-program than before training.
This adds further support to the idea that those workers are either
leaving the state for employment opportunities elsewhere, or are becoming
discouraged and withdrawing from the labor market.
Before program termination, the WIA participation groups were less likely
to be employed than the Comparison group (see Figure 6).
After program termination, there is no noticeable difference between the
groups. The WIA program appears to be allowing participants to become
indistinguishable from the average Wyoming worker, and that is an
important accomplishment. As previously discussed, after program
completion the employment rate for Adults increased. This was not the
case for either Dislocated Workers or the Comparison group, both of
which showed decreases in the percentage of individuals employed in Wyoming.
Findings in the success measure are most interesting. WIA participation
appears to be very effective in improving the economic lives of
participants. For example, 65 percent of Dislocated Workers experienced
at least one positive outcome from participation; many of those
experienced more than one positive outcome. The same is true for Adults.
Except for Adults who enrolled in a Wyoming community college, who
tended to withdraw from the labor market during their education, very
few participants had only one positive outcome. The majority of Adults
with a successful outcome increased their wages, decreased their
turnover rate, and gained employment in a living-wage industry. In
essence, they epitomize the unwritten goals of the WIA program.
Limitations
Wyoming has the smallest population in the nation. Because of the small
size, findings are not generalizable to other states. In addition, it is
impossible to perform detailed analyses, such as the effects of different
kinds of training, because the sample size is too small. A remedy is to
combine data for several states, primarily bordering states, so that a
regional picture of WIA training could be built. That kind of analysis
would be fairly easy to complete for Alaska, Nebraska, New Mexico,
South Dakota, and Wyoming because the available wage records and
demographic data are comparable for those states.
Another limitation is the lack of qualitative program knowledge of WIA.
Because the analysts are not case managers, there is no firm understanding
of common participant issues that affect the outcomes. For instance, if
transportation availability is a common obstacle, the number of training
opportunities is limited and outcomes could be affected. In order to give
broader coverage to those types of issues, a stronger relationship needs
to be developed between research and program staff.
Finally, there are limitations inherent in a quasi-experimental design. It
is impossible to completely match the control group to the WIA participant
group on only the simple demographic and economic variables available in
administrative databases. There are likely many other important variables
that were not controlled for because of limitations in the administrative
databases. Also, there are some issues that can only be addressed in
longitudinal analysis.
Summary
While the capacity to conduct true experimental design and replication
is limited, this study offers a powerful alternative analysis. By comparing
labor market experience between WIA participants and a comparable segment
of Wyoming’s workforce, it was determined that WIA participants basically
became indistinguishable from the rest of Wyoming’s workforce, an arguably
favorable outcome. However, the Wyoming study shows that no program effect
exists for wages or turnover, at least in the 24 months following program
completion. In the absence of a strong economy, participants may have failed
to become indistinguishable. Training programs likely have difficulty showing
success in economically challenged environments. Additionally, the federally
mandated outcome measures fail to reflect all of the successes of program
completers. ETA should consider changing the focus of WIA program evaluation
to measures that capture relevant information pertinent to employers, workers,
and program managers.
