It is with deep and profound sadness that we announce that our friend and colleague, Linda Houser-Marko, passed away on Thursday, January 9, 2020.

Your application should tell a story about your strengths, passions, and plans. But, that’s easier said than done when you’re still exploring your...

We are conducting a study of the aptitudes of video game designers.

The video game industry has come a long way from its beginning in the early 1970s.

JOCRF is in a unique position as a research organization because our clients are our research participants.

The majority of academic psychological research is done on the convenience sample of college students who are in Psychology 101 classes. Generally this limitation is acknowledged and yet tolerated. Research studies on adults who are in their early, mid, or late career are highly regarded.

For that reason JOCRF is fortunate to have such a wide and deep “basin” of data from thousands of past client-participants. Our tests are evaluated and age-normed upon those thousands...
