Analysis of fourth grade testing

Three hundred and ninetynine Grade 4 Brisbane children were given a battery o1 general ability and achievement tests. Means and standard deviations allowed construction of 15point scales for a Queensland Grade 4. A correlation matrix included indices concerning subtests of general ability and achievement tests. Comparisons with original A.C.E.R. coefficients were made. The matrix was factor subtests of general ability and achievement tests. Comparisons with analysed and rotated, three factors emerging verbal, performance and computational. A canonical correlation was performed and three significant elements emerged a verbal, a computational (or integrative or automatic sequential) and a problemsolving element
