The process used by the Texas Education Agency to update public school teacher certification tests in a statewide program in Texas is described. The testing program implemented is called the Examination for the Certification of Educators in Texas. After a policy review, advisory committees for 63 test areas prepared content frameworks, created objectives, and reviewed job analysis surveys prepared by classroom teachers and educators. A bank of test items was written for each test area and field tested at colleges and universities throughout the state. Minority educators reviewed the tests for bias. Recommended passing scores were obtained from teachers. The procedures described offer a useful model for keeping teacher certification tests up to date. (SLD)
