Abstract
A representative sample of educable mentally retarded males and females in public secondary day schools and state residential institutions participated in standardizing the Reading-Free Vocational Interest Inventory, a recently devised nonreading method to measure vocational likes and dislikes. Separate norms tables were prepared for males and females to convert raw scores on each interest scale to standard scores and equivalent percentile ranks. Test-retest reliability on subsamples were highly satisfactory. Validity coefficients obtained with concurrent testing were encouraging with many values significant at high levels of confidence. Predictive validity is yet to be established as well as needed research with populations other than the mentally retarded.
