The Secondary Level English Proficiency (SLEP) test is a measure of ability in understanding spoken and written English. It is designed for use with students entering grades 7 through 12 whose native language is other than English. Previously offered on a limited basis at test centers established by the Educational Testing Service, the SLEP is now available to secondary schools and community colleges worldwide. Results can be useful in making placement decisions about the following: (1) assignment to English-as-a-Second-Language (ESL) classes; (2) placement in a mainstream English-medium program; (3) exemption from a bilingual program; and (4) exit from an ESL program. The SLEP is a norm-referenced test with 150 multiple-choice questions. This guide describes the test, its purposes and uses, scoring, and details of administration. Sample questions are provided illustrating listening comprehension and reading comprehension (including grammar and vocabulary) portions of the test. Test ordering information is included, with an order form. (SLD)
