No results of standardized or local tests of ability, aptitude, attitude, affect, achievement, or aspiration may be used exclusively in the selection of children for referral, diagnosis, or evaluation. Such tests must be approved by the department in accordance with regulations issued by the board to insure that they are as free as possible from cultural and linguistic bias or, wherever necessary, separately evaluated with reference to the linguistic and cultural groups to which the child belongs.
