The Toolbox Revisited is a data essay that follows a nationally representative cohort of students from high school into postsecondary education, and asks what aspects of their formal schooling contribute to completing a bachelor's degree by their mid-20s. The universe of students is confined to those who attended a four-year college at any time, thus including students who started out in other types of institutions, particularly community colleges. The core question is not about basic "access" to higher education. It is not about persistence to the second term or the second year following postsecondary entry. It is about completion of academic credentials--the culmination of opportunity, guidance, choice, effort, and commitment. Appended are: (1) Changes in Demography, Geo-Demography, and Postsecondary Entry from the High School & Beyond/Sophomores to the NELS:88/2000; (2) Principal Features of the NCES Grade-cohort Longitudinal Studies; (3) Differences Between the High School & Beyond/Sophomore Cohort and NELS:88/2000 High School Record Variables, and Limited Imputation Procedures for the NELS:88/2000; (4) Technical Issues; (5) Populations Included and Excluded from the Study Universe; (6) Gradations of the Academic Intensity of High School Curriculum; (7) Logistic Models for Two Alternative Presentations of High School Background; (8) The Timing of Departure; (9) Course Categories Included in Aggregates for Participation Rates in the First Two Calendar Academic Years of Attendance; (9) Collinearity Statistic (Tolerance) for the Seven Steps of the Logistic Narrative; (10) So They Earned a Degree? Now, How Long Did It Take Them?; and (11) Tables on Miscellaneous Topics Raised in the Text. A glossary is also included. (Contains 61 tables.)
