Formally launched in September 2018, the ACT® Certified Educator™ program is a professional learning and credentialing program designed to help educators improve their teaching and tutoring strategies and skills and be fully equipped to support student learning in the core content areas of the ACT® test. In this study, participants' views of the program were examined following its expansion to math, reading, science, and writing subject-specific courses. Perceptions of the program's value and effectiveness were generally positive across courses. In addition, participants reported that their professional credibility was enhanced after earning certification and that they learned new information from the program that would benefit their students.
