Reviews of approximately 60 assessment instruments useful with young exceptional children are provided. Tests were selected on the basis of their popularity in eary childhood education literature and their frequency of use by educators in Wisconsin and Minnesota. Reviews are intended to provide descriptive information regarding the content, format, process of test construction, strengths, and limitations of a given test. Some reviews include comments from authorities who have evaluated the usefulness of the instrument. Each review usually provides the following information: test name, author/s, publisher, address, copyright date, price, purpose, description, range of children for which the test is appropriate, testing time, scoring, number of levels, number of forms, administration (whether individual or group), examiner (whether professional training is required), standardization, reliability, validity, discussion/concerns, and references. A matrix preceding the reviews serves as both a guide to the tests and a Table of Contents. The matrix provides information for the tests reviewed plus about 25 others according to age level; type (whether norm referenced, criterion referenced, or screening test); time; training required to administer; developmental areas assessed; type of scoring (whether profile, standard scores, percentile, or developmental age); and special normative populations for which the test is appropriate. A final section considers factors to consider when selecting a formal assessment instrument and tips for assessing young children with disabilities. (DB)
