This publication represents the first attempt to address the problem of adequate evaluation processes for testing language dominance and proficiency in bilingual education. It is produced by individuals intimately acquainted with the fields of language testing and bilingual education. Issues in language testing as well as its history are discussed. Evaluation criteria are established for tests: measurement validity, examinee appropriateness, technical excellence, and administrative usability. The following tests are described: 16 commercially available tests; 6 tests undergoing development or testing; and 2 tests used for experimental purposes. A final section provides a concise evaluation of these 24 tests according to the above-mentioned criteria. An appendix lists test development efforts in Chamorro, Cherokee, Crow, French, Marshallese, Miccosukee, Navaho, Papago, Samoan, and Yup'ik. (Author/AM)
