In Simple Words
Giving lower-scoring job candidates short-term work exposure works like a physical foot in a closing door. Instead of getting permanently shut out by low written screening test scores, the temporary work placement allows candidates to demonstrate real-world work habits directly to employers, overriding initial negative paper credentials.
Estimated experience gains at test-score percentiles
- 25th test-score percentile
- USD 11.01 more per day estimated
- 75th test-score percentile
- USD 2.20 more per day estimated
Eight-month model estimates. Ability interaction is not significant after standard Bonferroni correction; percentiles are model evaluation points.
See source →Research question
Job seekers with lower baseline cognitive or test-based scores face severe structural screening barriers and are disproportionately excluded from formal employment opportunities. Standard screening tests often filter out these candidates before they can demonstrate actual workplace productivity.
Participants
N = 227 urban Malawian male job seekers re-interviewed at the 8-month follow-up.
Study Design
Heterogeneity analysis within an RCT/IV framework interacting baseline composite ability scores (timed numeracy and literacy test results) with experimental job acquisition.
Results
Candidates at the 25th percentile of baseline ability gained a 25 percentage point increase in post-intervention employment probability and earned $11.01 more per day. In contrast, candidates at the 75th percentile experienced a 1.5 percentage point decrease in employment probability and earned only $2.20 more per day.
Takeaway
Prioritize low-scoring or lower-ability job applicants for short-term workplace exposure opportunities to maximize economic returns and overcome hiring screening barriers.

- Follow-up
Collecting more information about participants later in a study to see what has happened to them. The term can also mean the length of time researchers keep track of them.
ExampleResearchers interview the same workers three months after a programme ends. That later interview is a follow-up.
GET-IT glossary · Follow-up ↗Read more about follow-up →- Baseline
The starting measurements in a study. Researchers use these to compare what participants were like at the start with what happens later.
ExampleBefore a training programme starts, researchers measure workers’ earnings. That first measurement is the baseline.

The difference between two percentages.
ExampleA rise from 40% to 50% is 10 percentage points. Relative to the starting value, that is a 25% increase.

A study that uses chance, like drawing lots, to decide who receives each option being compared. Researchers compare the groups’ outcomes to estimate the effect of those options.
ExampleA lottery assigns volunteers to a training programme or a comparison group. Researchers then compare their outcomes.
