scholastic aptitude  \nMore specifically,the objective of the study was to relate the performance of students on two tests from the battery of Differential AptitudeTests(DAT)-Verbal Reasoning(VR)and Numerical Abuhty(NA)-to ther performance on other second level assessment instruments TheDAT battery,which was developed in the United States(3),was adaptedand standardized for use in Ireland(8)and has been used extensively inpost primary schools While scores on the separate VR and NA tests ofthe DAT were considered,the study focused prmarly on the combinedscore for the two tests,a VR-NA composite score The practice of usingthe combined score on the VR and NA tests as a measure of scholasticaptitude was encouraged by the authors of the American DAT test manualwho viewed the combined VR NA test score as tapping 'the same generalarea as most tests of scholastic aptitude'(3,p 6),norms were presented  \n(3,Ch 3)to facilitate use of the VR NA composite score as a measureof scholastic aptitude The extensive validity data(based on over 200groups of second level pupils)reported in the American test manual  \n(3,Ch 5)suggest that the VR NA composite score was a better predictorof course performance than scores on any of the eight individual DATtests,although the NA test score was the best individual predictor in mostcases reported,even for English and Literature  \nData are
