Supervisor Performance Ratings

Job applicants who earn high scores on our pre-employment tests earn significantly higher supervisor performance ratings than those who score lower. Optimize Hire proves this by conducting validation studies with researchers at the Wharton School. Validation studies are scientific experiments that show how accurately pre-employment test scores predict job performance outcomes like supervisor ratings. Experts at the Wharton School who complete our validation studies hold them to the accepted scientific standard of 95% confidence, also known as statistical significance.

The Optimize Hire team, along with researchers from the Wharton School, can conduct a validation study to prove how well our pre-employment tests predict supervisor ratings at your company. Click here to learn how.
