This directory is intended to provide technical assistance for Nevada school districts and other evaluators of preschool children in selecting appropriate instruments to use in the multidisciplinary process for special education eligibility. It is not a list of approved tests, and tests not listed in this directory may be appropriate for assessment. It is the responsibility of parents and professionals working together to develop a picture of the child's abilities, and these instruments may be helpful. In all, 56 tests are listed. Each test description describes the author, publisher, publication information, the range of children tested, and details about test administration and use. A "Discussion/Concerns" section mentions additional detail about the test and its use. Charts also divided the tests into groups as: (1) norm-referenced; (2) criterion-referenced; and (3) measures that can be adapted for use with parents. (SLD)
