What Can Public Data Say About College Closure Risk?

This study began with a synthetic screening cohort, then tested the same ideas against public College Scorecard and IPEDS records. The two cohorts tell very different stories.

The real-data output includes 1,516 institutions but only 6 observed closures. That is enough to expose weaknesses in the original models, but not enough to rank institutions confidently or support a deployment decision.

Same question. Two cohorts. Very different confidence.

The ADM Thesis

Three Models, One Lesson

Each tier adds complexity. The question is whether that complexity adds value — or just noise.

Tier 1: Screening Rule

Three financial ratios: enrollment trend, tuition dependency, cash reserves. In the real-data output, the reported threshold detected 0 of 6 observed closures. It remains interpretable, but this result does not validate it.

Q1: Risk Score

Tier 2: Multi-Variable Model

The logistic model reached 40% recall and 1.6% precision in cross-validation. With only six positive cases, those estimates are unstable.

Q2: Geography

Tier 3: Gradient Boosting

Gradient boosting reported an AUC of 0.901, but 0% recall at the selected threshold. The ranking signal is exploratory; it is not a calibrated closure probability.

Q5: ML vs. Rules

No model in the current public output is ready for operational use. The useful ADM lesson is the correction itself: promising synthetic results did not survive contact with a sparse real-data cohort. The next fidelity step is better outcome coverage and external validation, not a more elaborate model.

Limitations

What We Don't Know

Small closure sample. The current real-data output contains 6 observed closures. Model comparisons are therefore exploratory, and institution-level scores should not be read as validated forecasts.

Financial data limitations. Two key stress score inputs — tuition dependency and days of cash on hand — are estimated from IPEDS Finance surveys where institution-level data wasn't available. Where data was missing, we used sector-level averages. This is declared as a fidelity choice throughout the analysis.

Enrollment trends limited to recent years. Historical enrollment data covers a 5-year window. Institutions with longer decline trajectories may look stable in this window.
