It is widely known that the earnings of workers without college degrees have stagnated in recent years and employment rates, especially among men, have strongly declined (Groshen and Holzer, 2021; Reeves, 2021).1 The recent Covid-19 pandemic and recession exacerbated earnings and employment gaps by race/gender and education, and also generated millions more displaced workers (Hershbein and Holzer, 2021); and automation in the job market will no doubt create many more displaced workers over time. The “Great Resignation” of workers from many low-wage jobs also demonstrates a need for successful post-secondary education or training, so that earnings and upward mobility prospects among those with lower levels of education can rise.

For decades policy analysts have sought to identify cost-effective job training programs with lasting impacts for disadvantaged or displaced workers, with limited success. But a very promising model for such training has recently emerged: sector-based training, where people are trained for existing jobs in high-demand sectors that pay well for workers without four-year college degrees. Several rigorous evaluations studies (reported below) have found large and lasting impacts of several such programs on worker earnings and sometimes on college credential attainment (Holzer, 2021).

Indeed, this record of success motivated the Biden administration and the House of Representatives to include at least $10B of training for jobs of “in-demand sectors” in the Build Back Better bill which the House recently passed.2 The Workforce Innovation and Opportunity Act (WIOA), which will likely be reauthorized in 2022, also encourages state and local workforce boards to fund sector-based programs.

But the What Works Clearinghouse (WWC) of the US Department of Education, which summarizes the results of rigorous evaluation studies for policymakers and practitioners, released reports in November casting doubt on the effectiveness of two of the best-known sector-based programs for disadvantaged workers: Project Quest and Year Up.3

Both programs have been evaluated many times and are widely considered to be very successful. But, in each case, WWC provides evidence of only one or two positive impacts on specific measures of education or earnings, while claiming zero or negative impacts on most others. In many cases, the weak results are generated by WWC protocols for judging evaluation results that, while often sensible, can also be arbitrary in some contexts. And WWC failed to include several more recent reports in its summary that provide more positive evidence of longer-term impacts.

Below I argue that the best available evidence still suggests that Project Quest and Year Up, along with other sector-based programs, remain among our most successful education and training efforts for disadvantaged US workers. While major challenges remain in scaling such programs and limiting their cost, the evidence to date of their effectiveness remains strong, and they should continue to be a major pillar of workforce policy going forward.

Sector-Based Training: Evidence of Success and Why It Works

Sector-based training programs explicitly target key sectors of the economy, where labor demand is strong and where workers without college degrees can earn living wages, and train workers for jobs in those sectors – which include health care, information technology, advanced manufacturing, and transportation and logistics.

In doing so, they employ what is often known as a “dual customer” focus – treating employers as major clients whose interests in filling available jobs must be taken just as seriously as the workers receiving the training. Indeed, employers help produce the curricula in which students or workers are trained, and then workers are referred to them for subsequent employment. Key features of the approach include:

Furthermore, the relatively greater success of this approach (compared to more traditional training that omits an explicit demand-side focus) in improving worker earnings has been demonstrated in rigorous evaluations of several such programs, using randomized controlled trails (RCTs) to generate “gold standard” evaluation results. These studies have identified large and lasting impacts of sector-based training on the education and/or earnings of the disadvantaged, and are cost-effective over time.

These studies are summarized in an important recent paper by Lawrence Katz of Harvard University and his colleagues (Katz et al., 2020). They review several rigorous evaluations of sector-based programs that appear successful, though they focus primarily on the WorkAdvance program.5They also identify what causes sector-based training to be so successful: their ability to train workers for high-paying jobs and sectors, the transferable and certifiable skills that such training generates, and reductions of employment barriers to high-wage sectors, particularly for women and people of color.

Among the programs that Katz et al. identify as successful are Project Quest and Year Up. These two programs differ from each other in their approaches to employment and training and target quite different populations. Project Quest, first implemented in San Antonio TX in 1992, delivers training to community college students and helps them attain college credentials (such as certificates or associate degrees) in certain high-demand fields, like health care. In contrast, Year Up targets out-of-school youth; it provides six months of training to disadvantaged high school graduates (or GED attainers) in information technology or other high-demand fields, followed by six-month paid internships with private employers.

As Katz et al. indicate, Project Quest and Year Up have each been evaluated a number of times, in studies using RCTs, and the results have indicated strong positive impacts of each. Specifically, Roder and Elliott (2018, 2019, 2021) have demonstrated large and lasting impacts of Project Quest on worker earnings, lasting up to nine or eleven years. And Fein and Hamadyk (2018) and Fein et al. (2021) have shown that Year Up raises earnings by large amounts for disadvantaged youth as much as five years afterwards – a more positive finding than has been observed in any other youth training program to date.6

WWC Reports on Project Quest and Year Up

To help policymakers and practitioners identify which programs and approaches work or don’t work, the US Department of Education created the What Works Clearinghouse (WWC). For any given education program or intervention, WWC identifies all studies that have been done (as of a point in time), which use rigorous methods, and what the rigorous studies have found, on average.

To do this, WWC uses very specific protocols to determine which studies are rigorous, and which results in these studies are included in their reports as positive or negative evidence. Then, due to lags in the review and publication process, the reports often include only studies that were available at least a year before any report is published, and sometimes 2-3 years earlier.

WWC Reports on Project Quest and Year Up: What Did They Find?

WWC’s review of Project Quest is based on four studies that it deems rigorous enough to include in their review: 1) Roder and Elliott, 2018 and 2019; 2) Rolston et al., 2017; and 3) Juniper et al., 2020. Notably, only the studies by Roder and Elliott focus explicitly on Project Quest; the other two focus on other programs in Texas – the Valley Initiative for Development and Advancement (VIDA) in the Rio Grande Valley and the version of Capital IDEA that was implemented in Travis County TX – which were explicitly modeled after the original Project Quest, but now likely differ from it on implementation details.7 WWC’s review of Year Up is based on two studies: 1) Roder and Elliott, 2014 and 2) Fein and Hamadyk, 2018.

WWC’s report on Project Quest summarizes its measured impacts as follows:

WWC’s report of Year Up summarizes its measured impacts as follows:

WWC’s reports provide considerable detail and nuance on the data and estimation methods used in the impact studies, as well as how/why WWC summarized them as it did. Unfortunately, it is likely that many readers seeking information on the performance of PQ and YU will see only their shorter snapshots and briefs, rather than the longer reports that provide more nuance.

Were the WWC Reports Accurate?

I strongly believe that WWC’s summaries of Project Quest and Year Up – especially in the snapshots but also in the briefs and reports – paint portraits of both programs that are much less positive than what the extant research really shows.

There are two primary reasons for this: 1) WWC’s summaries of the studies they reviewed, based on some very specific protocols it uses, are somewhat incomplete and not fully accurate; and 2) More importantly, they did not review some more recently published studies, which appeared in 2021 and before the publication of WWC’s reports in November, which show much stronger positive impacts than those in what WWC covered.

Below I briefly summarize my reactions to the WWC reports, while more details are available in an online Appendix.

WWC’s Summaries

A closer look at the studies of Project Quest and Year Up reviewed by WWC shows that some of their concerns are very sensible, while others are based on a set of protocols that lend consistency to their summaries over time but are not always well-suited to certain analyses.

For instance, in these reports WWC corrects some statistical problems with the original studies (such as standard errors on estimates that weren’t adjusted for clustering and multiple observations) that, when adjusted, reduce their statistical significance. They note some cases where outcomes were not fully equivalent between the treatment and control groups at baseline, and also where some questionable statistical techniques were used to impute missing control variables.9 Various findings in the original reports were excluded for these reasons, and these are reasonable positions for WWC to take.

At the same time, the WWC reports:

Do sectoral training programs work? What the evidence on Project Quest and Year Up really shows Do sectoral training programs work? What the evidence on Project Quest and Year Up really shows

Overall, the results suggest that Year Up generates positive impacts on both short-term earnings and employment; WWC notes only the former. For Project Quest, the evidence implies not only positive impacts on academic credits earned and on credential attainment in the short-term (acknowledged by WWC), but also evidence on associate degrees attainment that is more mixed than WWC indicates.12 A closer look at the studies themselves also show positive medium-term impacts of PQ on earnings and employment, measured in Years 5 and 6.

More Recent Reports

Three very important additional reports have been released on these programs, beyond those summarized by WWC (and by Katz et al.). These include Roder and Elliott (2021) on Project Quest, Rolston et al. (2021) on VIDA, and Fein et al. (2021) on Year Up.

On Project Quest, the more recent study by Roder and Elliott reports significant (at the .10 level or higher) 10- and 11-year impacts on earnings and employment that are large and lasting (on top of the significant 9-year impact in their 2019 report). They also show positive impacts not only on certificate attainment but to some extent on associate degree attainment as well, and significantly in the target field of health care.13

On VIDA, Rolston et al. (2021) largely confirm the positive findings on postsecondary attainment that were apparent in their earlier report, with clearer evidence now of positive impacts on associate degrees as well as certificates and credits. While they find no significant impacts on earnings after three years, the positive impacts on both credit and credential attainment almost certainly suggest that positive impacts on earnings will materialize, given the clear labor market returns to postsecondary credits and credentials in the research (Backes et al., 2015; Holzer and Baum, 2017).

Regarding Year Up, Fein et al. find large and persistent earnings impacts at five years after random assignment that show no signs of fading out.

Had WWC included these reports in their summaries of Project Quest and Year Up – all of which were available well before the publication of its report – the positive impacts of these programs would have been more obvious. Indeed, summaries by the Pathways to Work Evidence Clearinghouse and the Arnold Foundation, published before the WWC reports, suggest stronger positive impacts of PQ and YU on education and employment outcomes than what the WWC reports.14


Sector-based training programs remain one of the most promising approaches to raising the earnings and employment of those without 4-year college degrees in America. Several rigorous evaluations in recent years suggest that they can have large and lasting impacts on worker earnings and are often cost-effective over time. For this reason, the Build Back Better legislation and other workforce development efforts focus heavily on scaling these successful interventions.

Unfortunately, the US Department of Education’s What Works Clearinghouse recently generated two reports summarizing evaluation evidence on two of the best-known sector-based programs – Project Quest and Year Up – suggesting that the impacts were much weaker than has widely been noted. But the more negative summaries produced by WWC were, in many cases, generated by protocols determining which studies to review and which findings to believe that may often be sensible but were too rigidly applied in this case.

A careful review of the studies they summarize, and especially three more additional ones that they failed to report (due to publication lags created by their review process), paint much more positive portraits of both programs. In particular, the full batch of studies demonstrate clear positive impacts on virtually all measures of postsecondary education by Project Quest, and on employment outcomes for disadvantaged students and workers by both Year Up and Project Quest. These more positive portraits are also consistent with the recent evidence reviews by Katz et al., the Pathways to Work Evidence Clearinghouse and the Arnold Foundation that we note above. Indeed, the positive impacts appear sufficiently large and long-lasting to render these programs cost-effective.15

We need to learn much more about these programs – for instance, how to maintain their cost-effectiveness when we scale them, and perhaps how to extend them to less work-ready individuals. In the meantime, the underlying success of these programs should not be challenged by research summaries with major shortcomings.

I believe that WWC can continue to play an important role in identifying what works; but, in the future, they should try to avoid the pitfalls that weaken the credibility of their summaries. Regarding the studies they review, I suggest the following:

And, when more recent evaluations have been published before WWC releases its reports on earlier evidence:

It would also be useful for WWC to provide more of this broader evidence in its “snapshots” and “briefs,” as well as its longer reports.
