Psychometric Analysis
Rigorous analysis and research are our areas of expertise. Our psychometric analysis team blends a detailed study of item response and results with expert judgment.
Overview
We review each item to determine its usefulness and ultimately the tests quality. Our process involves:
- Post beta test, results are collected and analyzed using classical item statistics reports.
- Usable items are sorted into equivalent forms that match blueprint specifications.
- A cut score is determined by Prometric psychometricians by using proven methods such as modified Angoff method and the Borderline Group method.
The end result is that the test is valid, reliable and legally defensible.
