Fifty-seven seventh and 60 eighth graders were divided into three reading ability groups. All were given the Wechsler Intelligence Scale for Children (WISC) prior to the study and the Gates-MacGinitie Reading Test Survey E for grades 7 to 9 immediately after the study. A practice sample was given before the tests on prepared vowel deletion and cloze passages. Performance on both tests was correlated with each other, with scores of the reading test, and with the WISC scores. Correlation between vowel deletion and cloze scores was found to be .43 for the total group. Vowel deletion correlated significantly with the reading test (speed, .51; accuracy, .63; vocabulary, .57; and comprehension, .51), and with the IQ test (performance, .39; full scale, .45; and verbal, .37). The correlation was higher for eighth graders on speed, accuracy, and vocabulary, but higher for the seventh graders on comprehension. The cloze test correlated with the reading test as follows: speed, .29; accuracy, .41; vocabulary, .55; and comprehension, .60. It correlated with the IQ test as follows: performance, .28; full scale, .46; verbal, .50. Generally, for all measures except verbal IQ and reading comprehension, the vowel deletion correlations were higher than or almost identical to the cloze correlations for the total population.
