The Role of Stanford Achievement Test 10™ Subtests in Sixth Grade as a Predictor of Success on ACT's Eighth Grade Explore Exam™
The purpose of this study was to determine if there was a predictive correlation between a specific sixth grade achievement test known as the Stanford Achievement Test 10 and the eighth grade college readiness assessment instrument known as the Explore Exam for a group of North Texas students. Following an assessment during sixth grade, via the sixth grade Stanford Achievement Test 10, the sample of 123 students was later administered the Explore Exam during their eighth grade year. A subsequent analysis of the data using the Pearson product-moment correlation coefficient revealed a statistically significant predictive relationship between the respective instruments. The Pearson correlation coefficients ranged from .25 to .69. Multiple linear regression analysis was also completed in order to identify the Stanford Achievement Test 10 subtests that were the most important predictors of performance on the Explore Exam. The R-square values ranged from .32 to .51. The results suggest a predictive relationship between the two instruments in the areas of math, science, English, and reading.
