This study examines the influence of item verifiability (non‐verifiable vs. verifiable), context (applicant vs. incumbent), and keying procedure on biodata mean test scores and validity. Concurrent and predictive validation studies were conducted using a sample of 425 call center incumbents and a sample of 410 call center applicants. Although applicants did not obtain significantly higher mean biodata scores, results provide support for the hypothesis that the non‐verifiable biodata composite would be less valid in the applicant context, while the verifiable biodata composite would be equally valid across both the applicant and incumbent contexts. The same pattern of results was obtained using both item‐ and option‐keying procedures. Implications for research and practice are discussed.
