Educational Testing Service

Educational Testing Service (ETS) is the world's largest private, nonprofit educational testing and assessment organization. Founded in 1947 by the American Council on Education, the Carnegie Foundation for the Advancement of Teaching, and the College Entrance Examination Board, ETS develops and administers standardized tests primarily for K-12 and higher education in the United States and globally. ETS is renowned for its industry-standard assessments, including the Graduate Record Examination (GRE), the Test of English as a Foreign Language (TOEFL), the Test of English for International Communication (TOEIC), and the Praxis Series for teacher certification. Beyond testing, the organization conducts extensive research in psychometrics, learning science, and educational policy, operating one of the largest research institutes dedicated to measurement in the world. In recent years, ETS has pivoted toward digital transformation and AI-powered assessment. This shift includes the major acquisition of PSI Services LLC in 2024, significantly expanding its footprint in the global certification and licensure markets, and the creation of ETS Strategic Capital to invest in emerging edtech startups.
