Abstract 1. There is significant correlation between the ACE total, quantitative, and linguistic scores and the AIA-I scores. The most consistent covariation obtained in the case of the total score rather than the quantitative or linguistic scores. 2. Students who scored below the median on the ACE total test averaged a higher percentile rank on the AIA-I test than would have been predicted from the ACE score, indicating possible over-achievement. 3. Students scoring above the median on the ACE total test averaged on the AIA-I percentile ranking approximately on par with their average ACE percentile ranking, indicating that achievement was on the level predicted by the ACE test. In conclusion, the ACE is a relatively accurate predictor of achievement in accounting as measured by the AIA-I.
