Many jobseekers—especially those without formal qualifications—struggle to prove their skills to employers, leading to mismatches, underemployment, and low wages
Employers often rely on proxies like education or experience, which may not reflect actual ability, particularly in settings where credentials are inconsistent or hard to verify
This insight draws on 21 randomized evaluations to assess whether third-party, credible signals of skills (like certification tests or digital badges) improve employment outcomes
Outcomes
Providing certified skills signals increased job offers and earnings in multiple studies—for example, in India, jobseekers who received a verified skills certificate were 33% more likely to receive a job offer
In the U.S., a soft skills certification increased interview callbacks by 20%, especially for candidates with weaker résumés
Signals were most effective when they were low-cost, widely recognized, and relevant to specific skills employers value—like digital literacy, teamwork, or technical ability
Implications
Invest in scalable certification tools—governments and workforce agencies should roll out low-cost, credible skills tests to help jobseekers signal ability without needing formal degrees
Integrate skill signals into public job platforms—link digital badges or test results directly to jobseeker profiles to help employers identify qualified candidates quickly
Prioritize relevance and recognition—focus on certifications that reflect what employers actually use in hiring decisions, and build employer awareness around these tools to increase uptake
