Changes to the Scholastic Aptitude Test (SAT) that will be introduced in the 1993-94 academic year are reviewed, with attention to edumetric factors such as relationship of curriculum and instructional practice to test design and the impact of the changes. The new SAT will put increased emphasis on critical reading skills to reflect developments in research and instruction. Vocabulary knowledge will be measured in context. Changes in the verbal test are responsive to widespread interest in considering the consequences for educational practice of what is included in important tests. In the mathematics section, new questions will require students to arrive at an answer instead of choosing one, and calculator use will be allowed. Current achievement tests will be expanded and enhanced by: (1) writing tests as part of the subject tests; (2) listening comprehension for language tests; (3) expansion of the subject tests to include Asian languages and English as a Second Language; and (4) modification of tests in mathematics and science to allow calculator use. A new writing test will replace the existing assessments. General recommendations for educational assessment and performance assessment are presented. There are three references. An appendix contains sample questions from the new test forms. (SLD)
