Our team of psychometricians and data scientists have partnered with clients to provide insights into security breaches, test-level timing, and fairness and bias.
Security
To prevent security breaches, we perform an item exposure analysis that identifies potential candidate misconduct using customized flagging reports.
Test Data
Test-level timing analyzes and evaluates testing data to ensure that candidates have enough time to complete a test.
Fairness and Bias
Our fairness and bias analyses examine pass rates by subgroup at the test level and examine item performance by subgroup with innovative Item-Response Theory (IRT)-based Differential Item Functioning (DIF) methodologies. These techniques help ensure that our tests are fair and unbiased and can help guide item development and provide feedback to educator preparation programs.
