Abstract
Correlacion coefficients are presented for 96 pre- and early elementary school children between the Stanford-Binet, Illinois Test of Psycholinguisdc Abilities, Wide Range Achievement Test, and California Achievement Tests (Lower Primary). The two achievement tests were highly correlated with each other (Mdn = .80) and the high (.89) correlation between Wide Range Reading scores and California Total Battery indicates the possibility of using the Wide Range reading score as a quick estimate of general achievement. The Binet Mental Age and ITPA Total Language Age were highly correlated with each other and about equally correlated with achievement variables, while only two of the ITPA subtests, Auditory-vocal Automatic and Auditory-vocal Association were moderately correlated with the Binet and achievement variables.
