Validity of the CELF-R, TONI, and sit for children referred for auditory processing problems

Recent changes in legislation for persons with disabilities have led to an increased focus on Central Auditory Processing problems. Test scores from the Clinical Evaluation of Language Functioning-Revised (CELF-R), Test of Nonverbal Intelligence (TONI), and the Slosson Intelligence Test (SIT) obtained from folders of 40 clients referred for auditory processing problems were analyzed to ascertain the validity of using these tests with a population on which these tests were not normed. All tests and subscales were correlated significantly. Even so, mean differences were present, with one exception, on comparisons of test scores. Moreover, females obtained significantly higher scores on the TONI than did males. Our findings generally support the validity of using these tests with a Central Auditory Processing sample.
