Does a College Degree Predict Job Performance?
In a study of 10,765 hires, a college degree was a weak predictor of job performance. Among agents with education data, production rates rose only slightly with education: high school 18.1%, associates 19.3%, bachelors 21.5%, masters 23.9%. The differences fell within overlapping confidence intervals, so the gaps were small and uncertain. The direction favored more education, but the effect was far weaker than behavioral assessment. A degree is a credential, and in this data it was not a reliable forecast of who would produce.

What the data showed
Across agents with evaluable tenure and available education data, production rates climbed gently with education level, from 18.1% at high school to 23.9% at masters. The differences were small and their confidence intervals overlapped, which means the data cannot confidently rank one level above the next. Education looked like a weak signal, similar to prior industry experience and far behind behavioral assessment. See what predicted best.
A degree is a credential, not a forecast
The reason mirrors why resume keywords fail. A degree describes something a candidate did in the past. It does not measure how they will perform in a specific role with specific demands. It can carry a weak signal about persistence or aptitude, but it is a noisy proxy, and screening hard on it removes capable people for a small and uncertain gain. See why keywords fail.
The wider evidence on degree inflation
This is consistent with research outside the study. The Harvard Business School and Accenture report Dismissed by Degrees, drawn from 26 million job postings and 600 employers, found that employers generally rate degreed and non-degreed workers in the same role as nearly equally productive, while a bachelor's degree increasingly gets used as a rough proxy for skills it does not actually measure. Requiring a degree where the role does not need one screens out capable candidates and shrinks the talent pool.
What this does not say
This is one carrier and one role, insurance sales. The effect was small, not zero, and the direction did favor more education. The takeaway is narrow: a degree is a weak screening signal for production, and a team that screens hard on it should check that choice against its own outcomes rather than assume it.
Frequently asked questions
Does a college degree predict job performance? In this study of 10,765 hires, only weakly. Production rates rose slightly with education, but the differences fell within overlapping confidence intervals, and education was a far weaker signal than behavioral assessment.
Should employers require a degree? It depends on whether the role genuinely needs one. Research on degree inflation finds that requiring a degree for jobs that did not previously need one excludes capable candidates for little measured gain.
What predicts performance better than a degree? In this dataset, personality and behavioral assessment were far stronger signals than education or resume keywords.
Is this specific to insurance? The data is from insurance agent hiring. The pattern, that credentials are weak proxies for production, is consistent with broader research, though the specific numbers are carrier-specific.
