The randomized evidence is unambiguous. A 2023 study published in the Journal of Political Economy found that structured workplace soft skills training produced 13.5% productivity gains and a 256% net return to the firm within eight months of program completion. J-PAL's review of the experimental literature reaches the same conclusion: structured soft skills training can improve employment outcomes. Research on virtual mock interviews finds that students rate the practice as useful for performing better in real interviews, and that the level of preparation before the simulation is the primary factor driving positive outcomes.
The evidence on the strongest sector-focused programs is just as strong. Year Up, evaluated through the federally sponsored PACE randomized controlled trial, produced a 30% increase in average annual earnings, more than $8,000 per year, that persisted through seven years of follow-up, with participants accumulating over $38,000 in additional earnings compared to the control group. Per Scholas, which pairs 15 weeks of IT training with career readiness coaching and placement services, produced cumulative earnings gains of roughly 16%, about $42,000 per participant, over ten years of follow-up.
The common thread across all of it is repetition. Graduates get better at interviewing by interviewing, and better at workplace communication by communicating, with feedback, many times, before the stakes are real. NACE data shows 84.6% of students rate themselves as very or extremely proficient in professionalism, while just 50% of employers agree. Graduates are not lying about their readiness. They have simply never received calibrated feedback against a real employer standard, so they have no way to know where they actually stand. Every participant should complete multiple full interview and workplace communication repetitions, with structured feedback after each one, before their first real interview.
