Abstract
Thirty pairs of first- and second-grade children were matched on; (a) race, (b) sex, (e) socio-economic level, (d) type of classroom assignment, (e) age, (f) mental ability, and (g) reading achievement. Each pair consisted of a once-retained first grader and a never-retained second grader. The children were white, low socio-economic slow learners from urban areas. Metropolitan Achievement Test scores for 1062, 1062, and 1064 were used as a measure of the reading and arithmetic achievement gain of the two groups over the two-year period of the study.
The test for matched pairs, using the data on the 20 matched pairs, showed both the reading and arithmetic achievement gain of the promoted group to be significantly greater than that of the non promoted group during the first year of the study. An analysis of variance, using the data on the 24 matched pairs whose achievement scores were available the second year of the study, showed both the reading and arithmetic achievement gain of the promoted group to be significantly greater than that of the non promoted group over the two-year period of the study. It was concluded that nonpromotion was not an aid to achievement.
