Relative reading achievement: A longitudinal study of 187 children from first through sixth grades.

This article reports results of a longitudinal study of relative reading achievement of 87 boys and 100 girls from 1st through 6th grades. Gates-MacGinitie Reading Tests (W. H. MacGinitie, J. Kamons, R. L. Kowalski, R. K. MacGinitie, & T. MacKay, 1980) data were drawn from records of 1 rural school district in Eastern Canada. There was a systematic relationship between gender and reading categorization in Grades 1-3, with more boys below average, and no systematic relationship in Grades 4-6. Probabilities of 6th-grade reading-achievement categorization conditioned on 1st-grade achievement were used to challenge the stability of reading categorization reported in previous studies. The courses of relative reading achievement over the 6 grades of key subgroups of children were followed to show how reading-achievement categorization changes. The implications include a case for early reading intervention and for reconsideration of the view that relative reading achievement is largely immutable.
