What is the primary function of ETS in the educational sector?

The primary function of ETS, or Educational Testing Service, in the educational sector is to offer assessments that guide and evaluate educational standards and programs. This encompasses a wide range of services, primarily focused on developing tests that measure knowledge, skills, and competencies in various educational contexts. For instance, ETS is known for designing standardized assessments such as the GRE, TOEFL, and Praxis series, which are essential tools used by educational institutions for admissions and program evaluations. These assessments help ensure that educational standards are maintained and that programs can effectively measure student learning outcomes and readiness.

In essence, ETS plays a crucial role in shaping educational practices through its assessment services, providing important data that can influence instructional strategies and policy decisions within education systems. The other roles outlined in the options do not encapsulate the core mission of ETS as effectively, as its primary focus centers on assessment rather than governance or providing materials.
