This study examined the relationship between the six scales of Locus of Control for Three Achievement Domains (LOCITAD) and scores on the Nowicki-Strickland Locus of Control Scale and the Rotter Internal-External Scale. Subjects were 140 students (78 boys and 62 girls) who ranged in age from 11-14 years. Results revealed significant correlations between scores on the Nowicki-Strickland Locus of Control Scale and the Success Intellectual Domain (r = -.⁵⁷, p < .01), Failure Intellectual Domain (r = -.21, p < .05), Success Social Domain (r = -.46, p < .01), Success Physical Domain (r = -.48, p < .01) measures of the LOCITAD. Scores from the Rotter I-E Scale were significantly correlated with the Success Intellectual Domain (r= -.37) and Success Physical Domain (r = -.34) scores of the LOCITAD with both coefficients significant beyond the .01 level. It was concluded that some support for the validity of the LOCITAD was evident. It was recommended that cross-validation investigations be conducted.
