Evaluated interscorer reliability of the Spatial Memory subtest, which appears on the Simultaneous Processing scale of the Kaufman Assessment Battery for Children. Responses from 19 gifted children were scored by two independent examiners. Results showed this subtest may be prone to scoring errors because no permanent record of responses exists.…

Seventy-seven hearing students were tested to compare the original and revised forms of the Tennessee Self Concept Scale (TSCS), and 75 deaf and 27 hard-of-hearing students supplied test-retest data on the revised form. Good reliability was established as compared to the original, and reliability of the revised TSCS was demonstrated over time.…
