The Educational Testing Service (ETS) is a nonprofit organization that develops and administers standardized tests to assess students' knowledge and skills. Founded in 1947, ETS is best known for creating the SAT and the GRE, which are widely used for college admissions and graduate school applications, respectively. Their goal is to provide fair and reliable assessments that help students succeed in their educational journeys. In addition to test development, ETS also conducts research and provides resources for educators and policymakers. They focus on improving education through data analysis and innovative assessment methods, ensuring that tests are valid and equitable for all test-takers.
