Software Database

This database was constructed by Dr. Gary Skaggs as a repository of information on software created to perform or assist with psychometric analyses.

It was created with support from the NCME Bradley Hanson Award. The database was last updated in July 2019.

Use the search and filter functions to find a certain software or narrow options by analysis, license, and measurement model.
