The Raven's Standard Progressive Matrices Test (1958) Was therefore, administered to 599, Seventh; ninth-, and eleventh-grade Ethiopian students who had a considerably heterogeneous. cultural and environmental experiences. It was hypothesized that, the mean scores obtained on the Raven's Standard Progressive Matrices Test would not be different when the subjects are grouped under type of schooling, socioeconomic status, grade level and sex. Different levels of factorial designs were employed to examine group mean differences, and simple and partial correlations were computed in examining relatio~ships between the Raven's Test and the treatment variables. The results of the study indicated that, mean scores on the Raven's Test vary significantly with type of schooling, SES, and grade level. No significant mean difference was obtained for sex. In addition, very low but significant correlations were obtained between the Raven's Test and the treatment variablea except wi th sex. The results generally support the previous. findings obtained in other contexts, and suggest that the Baven's Test is not a 'culture-fair' test of general mental ability. Future. research may be undertaken to find out the effect of factors considered in this study and other factors with regard to the usefulness of the Raven's Test, more specifically the influence of environmental experiences and academic achievement on the Bevan Test.enType of Schooling, Socioeconomic Status Grade LevelThesis
