HumRRO has conducted validity and reliability studies for the testing programs we serve.
Studies in this area include alignment studies, DIF, standard setting, and estimating different types of reliability. In addition, to test reliability issues, HumRRO has also conducted validity studies that examine relationships between test scores. In addition, we have conducted convergent validity studies with Pennsylvania’s assessment and college placement exams. Currently, we are conducting research on College Career Preparedness for the National Assessment Governing Board, on the effect of omitting NAEP items for the National Center on Education Statistics.
