This study was designed to rank the first 100 words of the "Great Atlantic and Pacific Sight Word List" according to learnability. The differences in the learnability rankings of the words due to the sex of the subject and the relationship between the learnability and frequency rankings of the words were also examined. Subjects in the study were 200 kindergarten pupils enrolled in eight northeastern and central Wisconsin elementary schools. No significant differences were found between the overall learning ability of males and females or between the learnability and frequency rankings of the words. It was concluded that a rank-order of the first 100 words of the "Great Atlantic and Pacific Sight Word List" had been determined; the sex of the subject seemed to be related to the learnability of some words, but the real significance of this relationship was open to question; and the frequency and learnability rankings of the words were not related.
