 Lindquist also used the ITED tests to help develop the Armed Forces Tests of General Educational Development, better known as the GED.In 1958 at a conference sponsored by the Educational Testing Service (ETS), Lindquist presented "The Nature of the Problem of Improving Scholarship and College Entrance Examinations".Lindquist argued entrance examinations should evaluate students’ readiness to perform college-level work, and should, therefore, be tests of achievement and not of innate intelligence or aptitude, a clear challenge to the test then known as the Scholastic Aptitude Test (now called the SAT).
