The concurrent validity of the recently published Perkins-Binet Tests of Intelligence for the Blind was examined. Twenty-eight students from a residential school for blind children served as subjects. Although high correlations were obtained between both forms of the Perkins-Binet and the Wechsler scales of intelligence, there were substantial differences in the standard deviations for the different tests. The authors recommend further evaluation of the Perkins-Binet tests.
