A need existed to develop a graphic procedure to predict student success in 2-year engineering technology programs, based on ACT scores and high school grades. The study stemmed from the need to help students identify their chances of success, to help students clarify their goals, and to indicate needed institutional responses. Regression analysis determined how well college achievement correlated with a composite of high school grades and ACT scores. Records of 48 students from September 1970 through June 1973 provided the data. The analysis resulted in a coefficient of correlation of r = .85 to provide a fairly high predictive measure. The paper illustrates a reliable means of objectively predicting student success based on ACT scores and high school grades. (Author)
