Abstract

This study examined the test-retest reliability of the Test of Visual Perceptual Skills (nonmotor) (TVPS). The sample consisted of 30 first-and second-grade children (aged 6years through 8 years) with identified learning disabilities. The TVPS was administered on two separate occasions that were 1 to 2 weeks apart. The intraclass correlation coefficient for the total test standard scores was .81. The intraclass correlation coefficients for the subtests ranged from .33 (Sequential Memory) to .78 (Form Constancy). The primary finding from this study is that TVPS scores on the total test show adequate test-retest reliability for use in clinical settings. The scores on the subtests, however, should he used with extreme caution, as the test-retest reliability estimates were low.
