Investigated with 129 kindergarten children were test-retest reliability and validity of the Developmental Test of Visual Perception (DTVP), and changes in factorial relationships among the five DTVP subtest after a 10-week use of the program of M. Frostig. (MC)

Rotters' internal external scale failed to demonstrate adequate degrees of interval consistency for Blacks. The unreliability of the dimension among Blacks was pervasive. Such unrealiability was specific to Blacks: there was satisfactory internal consistency for Anglos and Chicanos. The theoretical and methodological implications of these findings…

This review looks at these changes and their impact on the quality of the instrument: alteration of age-range from 5-15 to 6-16; development of new norms; improvement of manual in format and function; and a number of old items deleted and new ones added for the subtests. (RC)
