Educational Testing Service, founded in 1947, is the world's largest private nonprofit educational testing and assessment organization. It is headquartered near Princeton, New Jersey. ETS develops various standardized tests primarily in the United States for K–12 and higher education, and it also administers international tests including the TOEFL, TOEIC, Graduate Record Examination General and Subject Tests, and The Praxis test Series — in more than 180 countries, and at over 9,000 locations worldwide. Many of the assessments it develops are associated with entry to US tertiary and quaternary education institutions, but it also develops K–12 statewide assessments used for accountability testing in many states, including California, Texas, Tennessee and Virginia. In total, ETS annually administers 20 million exams in the U.S. and in 180 other countries. Wikipedia [ - ]
