The ACTFL Assessment of Performance Toward Proficiency in Languages (AAPPL, https://www.actfl.n.d.org/assessments/k-12-assessments/aappl) assesses proficiency in 11 languages for students in grades 3 to 12 and is often used to award the Seal of Biliteracy. While arguments for the valid interpretation and uses of the AAPPL have previously been made, recent developments in test use, test administration, and the availability of additional research on the test motivate an updated, comprehensive evaluation of the AAPPL. This test review provides information on test purpose, tasks, administration, scores, developer and publisher contact information, and pricing details as well as a critical review of validity evidence pertaining to evaluation, generalization, explanation, extrapolation, utilization, and consequence implication.
