JA_Limiting Competition flexMIRT Software_Redacted.pdf

This document is a Special Notice regarding the Department of the Army's intent to sole source the procurement of the flexMIRT software from Vector Psychometric Group, LLC. The Defense Language Institute Foreign Language Center's Language Proficiency Assessment Directorate requires the flexMIRT software to analyze large datasets of Defense Language Proficiency Test item response data in order to maintain the accuracy, reliability and validity of the testing instruments. The flexMIRT software is considered the most advanced item response theory software and is the only software capable of the multivariate, multidimensional item response theory analysis required to process the large data volumes. No other statistical software possesses the capabilities and data management capacity of the flexMIRT software. Procurement of the flexMIRT software is deemed essential, as failure to do so would adversely impact the analysis and reporting of DLPT examinee proficiency scores relied upon by military units and DoD agencies.
