Educational Testing Service (ETS): Overview, History and Role in Assessment

What ETS does

ETS designs assessments that measure academic knowledge, subject-matter mastery and language proficiency. These assessments serve multiple purposes: admissions testing, placement and placement diagnostics, professional licensure and certification, program evaluation and large-scale accountability testing in public education systems. ETS combines test development, psychometric research, scoring, test delivery and reporting under one organizational roof.

Major tests and services

ETS is best known for several widely used examinations. Examples include:

• TOEFL (Test of English as a Foreign Language), an English-language proficiency measure used for academic admissions and visas.
• TOEIC (Test of English for International Communication), focused on workplace English.
• Graduate Record Examination (GRE) General and Subject Tests, widely used in admissions to graduate programs and for research benchmarking.
• The Praxis series and other assessments used for teacher certification and licensure.

ETS develops standard testing content and delivers exams across many formats, including computer-delivered and paper-based administrations. In the United States and abroad, its assessments are used by institutions, agencies and employers to make high-stakes decisions.

Geographic reach and sectors served

Although headquartered in the U.S., ETS administers exams globally, operating test centers and secure delivery systems in many countries. Its assessments are used by K–12 systems, colleges and universities, licensing boards and corporations. Within the United States, ETS produces materials for both K–12 accountability programs and for admissions to undergraduate education and graduate schools, as well as for international candidates seeking entry to institutions in English-speaking regions. The organization reports that it handles millions of test administrations annually across hundreds of countries and thousands of sites.

History, research and standards

Since its founding in 1947, ETS has combined operational testing with an emphasis on measurement science and research into assessment validity, fairness and reliability. The organization conducts psychometric research, publishes technical reports and contributes to professional standards in educational measurement. Over time ETS has adapted to technological change, expanding computer-based testing and remote-proctoring options while maintaining procedures for security and score integrity.

Importance and distinctions

ETS is one of several major testing organizations; it is distinguished by its nonprofit status and a broad portfolio that spans language testing, graduate admissions and teacher assessments. Its work influences admissions policies, credentialing standards and educational accountability practices. At the same time, ETS and similar organizations are part of ongoing debates about the role of standardized testing, equity in assessment, and how best to measure learning and potential.
