The GED[R] English as a Second Language (GED ESL) Test was designed to serve as an adjunct to the GED test battery when an examinee takes either the Spanish- or French-language version of the tests. The GED ESL Test is a criterion-referenced, multiple-choice instrument that assesses the functional, English reading skills of adults whose first language is not English. The purpose of this report is to provide some background and psychometric information regarding the ESL Test. Sections of the report provide an overview of the test specifications, estimates of reliability (including internal consistency and classification accuracy), and evidence supporting the validity of test score interpretations.
