This guide has been created to accompany the Lancaster, Pa., School District's Bilingual/ESL Reading Assessment Materials. The guide includes reading tests and information about how the tests were made, about how to give and score the tests, and about how to use test results. The tests are designed to help the teacher monitor changes in students' language proficiency and to give the student the opportunity to receive fair and accurate information about his language development. The Reading Assessment Materials themselves consist of short reading passages in which students are required to fill in blank spaces with appropriate English words or phrases. (CHK)
