Statisticians and Psychometricians


ETS statisticians and psychometricians work to ensure that all ETS exams meet the standards of reliablility, validity and fairness. A test is:

  • Reliable if it produces consistent scores among different testing conditions or versions used
  • Valid if it can be demonstrated to measure the traits, knowledge or skills it is intended to measure
  • Fair if no group of students is either advantaged or disadvantaged due to factors such as the language or content of the questions

Our standards for test performance are the most rigorous in the field. Because our tests are reliable, valid and fair, those who take, use and rely on our assessments can do so with confidence.

Student-performance Assessments

Depending on the subject, AP Exams may require students to produce recorded spoken responses in another language or submit portfolios of original art.

A modified version of the Praxis III test can also be used as a training program for both student teachers and beginning teachers.
