Our personality assessment is based on the Big 5 Model of personality which is considered the most empirically supported model of normal personality traits. It’s thought that these traits represent broad domains of human behavior and are at the highest level of the personality hierarchy. This particular assessment was researched and developed by Dr Leonard Goodstein, a previous CEO of the American Psychological Association, and Dr Richard Lanyon, a previous Associate Professor at Harvard Medical School.
Each of the scales has been analyzed for internal consistency and factor purity. Each meets commonly accepted psychometric standards; reliabilities as measured by Cronbach’s alpha range from .61 to .83 with a median of .76, based on 151,429 cases.
Norms for each of the scales were originally based on over 150,000 cases and are regularly updated as more data has become available. So far, over 20 million people world-wide have taken the assessment
My complements to a well developed and comprehensive course. I also greatly appreciate the reasonable price which is an excellent value.
Best $24 spent. Simple and direct to the point material, especially with minimal study time.
Got the job offer – thanks again!
A great way to study and get into the mindset though the practice tests have a tendency to repeat questions on the numerical part
Thanks for the feedback, James. Regarding the repetition of questions in the numerical part, we’re not aware of any duplicate questions, but there may very well be a few questions that repeat the same mechanism/logic pattern. We will contact you privately to look into the matter in greater detail.
12MinPrep is a GREAT value. I felt confident going into the test and found the actual test was not as difficult as the practice — which is a good thing. The combination of video tutorial, explanations of answers and the additional element of timed practice was well done. Thank you, Gideon.
