title: Test-retest stability of the Hiskey-Nebraska Test of Learning Aptitude in a sample of hearing-impaired children and adolescents.
abstract: The test-retest stability of the Hiskey-Nebraska Test of Learning Aptitude (H-NTLA) was examined in a group of hearing-impaired children and adolescents. Test-retest correlations for subjects retested after approximately 1 year, 3 years, and 5 years were .79, .85, and .62 respectively. These findings are similar to those reported for normal subjects in studies using verbal intelligence measures. In spite of reasonably high test-retest correlations, more than one half of the sample showed a 10-point or greater difference in Learning Quotient between the two evaluations, and more than one third of the sample showed a 15-point or greater difference. These findings demonstrate the necessity of basing important decisions on more than one measure of intelligence.
