美国教育考试服务中心（英语：Educational Testing Service，缩写：ETS），是世界上最大的非营利教育测试和评估组织，成立于1947年。其总部位于美国新泽西州劳伦斯镇。但因其所在地的邮编08540的美国邮政标准地址为普林斯顿，因此常被不熟悉美国邮政标准地址经常和物理地址不一致这一现象的人误以为位于普林斯顿。美国教育考试服务中心也同时使用唯一的美国邮编08541用以应对大量的邮递往来。

美国教育考试服务中心开发出了若干种面向K-12以及高等教育的标准化考试，同时还在超过180个国家、9,000个地区管理着包括托福、多益、GRE以及Praxis等在内的国际考试。其开发的许多评测都与美国的本科以及研究生教育有关，但它也为包括加利福尼亚州、德克萨斯州、田纳西州和维吉尼亚州的许多州的小学、中学开发评估体系。总的来说，ETS每年在美国及其他180多个国家运营着2千万次考试。

Educational Testing Service (ETS), founded in 1947, is the world's largest private nonprofit educational testing and assessment organization. It is headquartered in Lawrence Township, New Jersey, but with a Princeton address.

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 (Test of English as a Foreign Language), TOEIC (Test of English for International Communication), Graduate Record Examination (GRE) 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 (undergraduate) and quaternary education (graduate) 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.
