Abstract

The purpose of the study was to evaluate the appropriateness of the Hiskey Nebraska Test of Learning Aptitude as a measure of ability for Navajo students with suspected learning difficulties. Item analytic procedures were employed for the 61 students in the younger group (ages 5-10) and for the 57 students in the older group (ages 11-17).

Using Hoyt's analysis of variance routine, reliability estimates of .87 (younger group) and .81 (older group) were obtained. The majority of the items discriminated in the appropriate direction for both subtest and total test scores.

It was concluded that the Hiskey Nebraska Test of Learning Aptitude would give acceptably reliable and consistent results for Navajo children with suspected learning difficulties. Further research to demonstrate validity of the instrument for this population was discussed.
