Further Validation of the Nor Cal Questionnaire: Secondary Validation.
Kester, Donald L.
Primary validation of the Nor Cal questionnaire was accomplished in Phase 2 of the Nor Cal Attrition Study. The results of the primary validation were reported in the document entitled, "Phase 2 Final Report," (ED 039 879). The primary validation showed that the consortium-wide empirical validity varied from .65 to .67 depending upon whether or not the ACT aptitude test scores were incorporated into the predictive equation. In terms of the primary validation the research question was, "What proportion of first-time, full-time freshmen were correctly identified by the Nor Cal questionnaire predictive equation as either potential dropouts or potential persisters?" For the secondary evaluation, another research question also dealing with the predictive validity of the instrument emerged: "Are there significant differences between the subsequent performance levels of these groups?" This secondary validation is therefore concerned with comparing attrition rates, units completed, and grade point averages between groups of entering freshmen for whom appropriate scores were known. The results of this validation study show that when performance levels of students who are designated as potential dropouts by the Nor Cal questionnaire are compared with the levels of other students, it is clear that potential dropouts do: (1) have a significantly higher dropout rate, (2) complete fewer units, and (3) have lower grades.
