A benchmark GPA of 2.50 was established for creating the student groups. The 2.50 mark is typically considered the minimum acceptable GPA for maintaining good standing at most college and universities. Using z-score

computation, the three groups were low (GPA < 2.50), moderate (GPA from 2.50 to 2.97, with 2.97 representing a z-score of +1), and high (GPA > 2.97). Findings Results shown in Table 1 indicated that there was no overall correlation between the NSSE factors and the continuous variables under study, which were time to graduation (in days) and GPA at graduation. This indicates that there is no statistical evidence that the NSSE instrument is of value when considering its predictive validity related to the two outcomes of interest in this study. And, why should it? NSSE was never designed to measure these types of student outcomes, although it certainly would be encouraging if measures of engagement had some relationship to the sorts of outcomes that are of concern to senior administrators and governance officials. However, further investigation using multivariate analysis (MANOVA) did yield some interesting findings related to a statistical associations between groups of students and their NSSE scores, time to graduation, and GPA.
