This battery of test instruments is one of a set of three developed for use in the study of bilingual (English-Spanish) instruction programs and other compensatory programs in Texas. The tests are to be individually administered and are designed to measure children's basic language competence via the perceptual and motor sides of linguistic and communicative phenomena. In this manual, guidelines for the selection and training of test administrators suggest desirable professional and personality qualifications. The importance of a trial testing period is stressed. General directions are given for establishing rapport with the child to be tested and for giving appropriate responses to the child during testing. Forms A and B of the tests in both language versions are included. Samples in the appendix include pictures for the oral vocabulary tests, the scoring sheet for subtests, and the rating sheet of the child's interpersonal behavior in an interview with the test administrator.
