The purpose of the Special Interest Group (SIG), Test Validity Research and Evaluation SIG, is to provide a forum for bringing together educators and researchers interested in contributing to theory and practice of validity in education, assessment, and testing. The SIG encourages presentation, discussion, and interaction related to the development of theoretic and practical methods for measuring validity. Pursuant to these purposes the Test Validity Research and Evaluation SIG might elect to publish its own newsletter, or invite prominent speakers to present at annual business meetings, or hold occasional conferences supplementing AERA meetings.
