The document discusses nonverbal intelligence tests and their use in evaluating students from diverse linguistic and cultural backgrounds. It provides guidelines for determining which intelligence tests are appropriate for a given student based on their individual characteristics and backgrounds. Nonverbal tests may be preferable to verbal tests for students with language deficiencies or those from minority ethnic groups to minimize cultural and linguistic bias. The results of verbal and nonverbal tests should both be considered to get a full picture of a student's abilities.
