A handful of US workforce programs have randomized proof that they raise earnings 20–30%. Florida is scaling apprenticeships and certifications fast, but it tracks growth and wages, not what its programs actually cause.

The 30-second version
Training for specific in-demand jobs, with employers at the table, has the strongest proof: Year Up +30%, Project QUEST +20%.
In high school, Career Academies raised earnings 11% a year for eight years, and 17% for young men.
Florida apprentices out-earn new bachelor's grads in year one, but we found no randomized test of Florida's own programs.

The model behind the proof
The programs with proof don't just train. They connect training to a specific employer need.

Employers insideYear Up pairs six months of training with a six-month internship at a major firm.

How strong is the proof, by program?
The strongest proof sits outside Florida. Florida's biggest efforts sit in the "counts" column.

Reality check
What you've heard vs. what the research says
You've heardJob training programs don't work.
Research says
Randomized trials found Year Up raised earnings 30% and Project QUEST 20%, years after training ended.
You've heardThe big-name programs are the proven ones.
Research says
Job Corps showed no significant long-run earnings effect for its full sample. Per Scholas wasn't significant at year 10.
You've heardAny credential is a good credential.
Research says
Florida's top high school certification was Adobe Photoshop. Certifications there were linked to more associate degrees but fewer bachelor's.
You've heardRecord enrollment proves the program works.
Research says
Growth counts show reach, not results. Only 62% of Florida apprentices who completed finished on time.
Guess first
In Florida, who earns more in their first year: new bachelor's grads or apprenticeship completers?
Apprenticeship completers: $48,405 median first-year earnings vs. $45,364 for bachelor's grads. By year five, state college career certificate holders reach $61,836. These are descriptive numbers, not proof the programs caused them. Florida Economic Security Report 2025
The uncomfortable question
Are we funding programs by headcount or by results?
Florida's $105 million Pathways grant served more than 20,000 people, and its reports celebrate growth. But growth is what gets counted. The programs with the best proof earned it by testing against a control group, and that's the evidence employers and taxpayers can rely on.
So what?
What to do with this
Educators
Push students toward certifications employers value, not the easiest ones to pass.
Build career-themed pathways with employer partners, the Career Academy model.
Publish what your completers earn and where they work.
Policymakers
Tie part of workforce funding to earnings gains, not enrollment counts.
Commission a rigorous evaluation of one flagship Florida program, such as preapprenticeship.
Report outcomes by credential so families can compare.
Employers & talent teams
Partner with programs that have randomized proof, like Year Up's internship pipeline.
Help design the curriculum. The winning programs train to a specific employer need.
Track retention and performance of hires by source, so you know which pipelines deliver.

Finding
Where sources agree
Sector-focused training tied to employers produces large, lasting earnings gains in randomized trials.
Gains often start after training ends; earnings can dip while people train.
Results vary a lot by provider, even under the same model.
Where they conflict, and why
Florida's data look strong, but they describe completers, not causal impact.
High school certifications raised associate degree completion but lowered bachelor's completion. Whether that's good depends on the goal.
Job Corps' long-run results are disputed: one analysis found gains for older participants; critics call that a likely false positive.
The strongest counter-case
Trial participants applied and were accepted, so results may not carry over to everyone.
WorkAdvance showed that even proven models can fade: only one of four providers had a significant year-10 gain.
The trials were small, some a few hundred people. Florida's scale is untested.
Still unknown
Causal impact of Florida's apprenticeship and CAPE programs.
How many Florida apprentices are high school students or career changers.
Whether employers retain and promote program hires at higher rates.
Long-term earnings for P-TECH graduates.
What would change the verdict
A randomized or strong quasi-experimental study of a Florida apprenticeship or preapprenticeship program, tracking earnings for five or more years against a comparison group.
