Abstract:
The purpose of this study was to investigate the validity of a revised version of the Test of Visual Analysis Skills (TVAS). Data are presented from testing 198 subjects in two elementary schools with two versions of the TVAS and a second perceptual skills test (VMI). Within-age-group, between-school statistical comparisons strongly support the validity of the revised TVAS.
