Stopouts and Readmits: Using Student Record and NSC Data to Predict Re- Enrollment Jerret K. LeMay, Research Analyst, Institutional Research & Planning Binghamton University Funded through the State of New York / UUP Professional Development Committee

Why? Stopout Report Gap in Enrollment Projection Model (EPM) – Enrollment Estimates by: UG/GD, school, New / Continuing / Returning – Feeds Housing Estimates, Tuition & Fees Projections

Literature Horn (1998) - majority of stopouts (64%) return to higher education, and 42% of those re-enroll at the same institution they left. 27% of stopouts return to their original institution Adelman (1999) - alternating and simultaneous enrollment patterns, “portfolio building,” where the majority (61%) of those who attended two schools returned to the first.

Goal Predict, at the aggregate level, the number of readmitted students for a given semester using student record data and data from the National Student Clearinghouse (NSC)

Data Submitted to NSC 12,654 records of degree-seeking and non- degree undergraduate stopouts – “stopout” = did not receive degree & did not register for next major semester – Fall 1992 until Fall 2003 – instances, not necessarily people

What came back 17,254 records Business decisions – Dates vs.Years/semesters – Trumps (co-enrolled, FT/PT/Unknown etc.) – Date of initial enrollment – Merge back into student record dataset

Data Structure Person-period dataset - each student had a number of separate records equal to the number of semesters under consideration. Student record information existed for semesters in which the students were enrolled, and blank records were inserted for subsequent semesters. Person-period dataset Merged in NSC data “ugread” – dependent variable - readmitted as an undergraduate student in the next (major) semester Springs only (predicting fall readmits)

Before the Regression… Descriptives – Example: BU was institution of first choice for 49% of returning students, compared to 27% of non-returning students Bivariate – like frequencies, # of semesters missed, financial aid info, type of transfer institution (if they did transfer), and whether BU was the institution of first choice

Multivariate Model Logistic Regression 3 Criteria: – Variable significant – Variable improved the fit (-2 log likelihood) and quality (c) of the model – Improved Predictive accuracy (aggregate)

Significance Analysis of Maximum Likelihood Estimates Standard Wald Pr > Parameter DF Estimate Error Chi-Square ChiSq Intercept <.0001 Missed 1 semester <.0001 Medium need Trans NY 2yr <.0001 Missed < yrs at BU <.0001 Missed < nd sem senior <.0001 PLUS Loan amount BU first choice

Fit and Quality Model Fit Statistics Intercept Intercept and Criterion Only Covariates AIC SC Log L Association of Predicted Probabilities and Observed Responses Percent Concordant 84.6 Somers' D Percent Discordant 11.5 Gamma Percent Tied 4.0 Tau-a Pairs c 0.865

Predictive Accuracy Spring ugread predicted diff abs_diff ======== Intercept-only model = 77

How Did It Do? Fall 2004PredictionActualDifference New method Old methods: Previous year year average year average

Other Significant Variables? Many significant variables which also made for better model, but didn’t improve aggregate predictive accuracy Variation from year to year (significance, parameter estimates, standard error)

So? NSC Enrollment Search – Despite limitations Person-Period Dataset – Incorporation of NSC data – “Carry forward” – Flexibility Regression – three criteria
