Research and Design

ETS has rigorously pursued ongoing research to ensure test quality for more than 50 years. Using a high-quality test means more accurate decisions about international applicants for your institution.

Our in-depth Classroom Needs Assessment identifies the skills students need to succeed in an academic environment. Only those tasks that demonstrate test takers’ academic English-language proficiency are included in the test.

We have issued more than 150 research reports to provide a strong research base to support our test design — so you can be sure you’re making an accurate decision about academic English-language proficiency.

  • Creating test questions based on test specifications
