Originally developed in 2004 at McMaster University for medical school admissions, Casper’s open-response format allows for freer expression from applicants. This can help reduce score differences between majority and minority groups.

This has made Casper the most trusted and widely used situational judgment test (SJT) in higher education admissions. To date, more than 600 programs around the world have used Casper, including in the United States, Canada, Australia, and the United Kingdom. Since 2016, over 700,000 applicants have taken Casper, including 96% of US medical school applicants. 

We test ourselves, too.
