This challenges universal grade-inflation claims without proving learning is unharmed.","sledRelevance":"Direct U.S. public-university relevance for assessment governance; institutional results do not establish effects at every college.","evidence":"The 2015–2025 source sample contains 156,135 students and 87,936 offerings; the balanced analytic sample is smaller. A human-validated LLM syllabus pipeline feeds difference-in-differences comparisons. Table 1's preferred GPA regression uses 1,195,110 student-offering observations.","architectureImplications":"Interpretation: An institutional research pipeline can join approved syllabus classifications with deidentified outcomes, but needs stable identifiers, annotation quality checks and reproducible model versions. This is an analytics workflow, not evidence for autonomous advising agents.","governanceImplications":"Interpretation: Keep course outcomes, actual tool use and independent learning conceptually separate. Require sensitivity analysis and an explicit causal review before policy claims.","securityPrivacyImplications":"Interpretation: Keep student-level joins in a restricted institutional environment, minimize exports, and audit access. A cloud annotation endpoint should receive only approved content; hybrid or local processing depends on institutional constraints.","caveats":"Preprint; grades are not direct learning measures. Grade parallel trends fail even before COVID, precluding strict causal interpretation. Exposure is inferred from syllabi; model error, grading changes and survey selection remain. Event period spans years.","streamIds":["student-success"],"roles":{"sales":"Interpretation — Provosts, institutional research teams and faculty governance may face conflicting claims that AI necessarily inflates grades or leaves learning unaffected. Ask what evidence supports current assessment policy, which outcomes matter and whether historical course data are comparable. A credible value hypothesis is better local measurement and less overconfident policy. Offer a bounded assessment-data diagnostic, including annotation validation and a review of alternative explanations. This preprint supports questioning universal claims; it does not prove that an institution's assessments remain valid. Do not promise learning improvements, reliable cheating detection, retention gains or savings from a catalog-level null result.","engineering":"Interpretation — Fit this approach to retrospective institutional analytics with authorized data access. Build stable course and term joins, separate identifying data from analysis, and version syllabus classifiers and human labels. Prerequisites include comparable historical records, an assessment taxonomy and statistical expertise. Deployment constraints include incomplete syllabi and changing course structures. Use access controls, restricted exports and retention rules; evaluate local processing if cloud disclosure is unacceptable. Proposed validation: double-code a held-out syllabus sample, measure classification errors, reconcile record counts and test sensitivity to baseline choices. Demonstrate parallel-trend diagnostics explicitly. A functioning pipeline cannot repair an unsuitable causal design or measure unobserved learning.","delivery":"Interpretation — Institutional research should own the analysis plan, with registrar data stewards approving joins and faculty reviewing assessment classifications. Developers implement repeatable transformations; statisticians document assumptions and sensitivity analyses. Launch only after data-access and privacy review, then give faculty a clear route to correct course metadata. Proposed acceptance criteria include reconciled source-to-analysis counts, a documented human-label audit, reproducible results and explicit limits accompanying every policy-facing chart. These are proposed criteria. Adoption means decision-makers understand uncertainty, not just receive a dashboard. Risks include inappropriate student profiling, misclassified assessments, changing grading practices and treating a statistically insignificant result as proof of equivalence."},"retrievedAt":"2026-09-07T03:00:58Z","enrichedAt":"2026-09-07T03:05:38Z","enrichmentBasis":"retrieved source","accessibilityWorkforceImplications":"Interpretation: Include institutional researchers and faculty assessment experts; do not use aggregate findings to dismiss student accessibility needs or inequitable access.","procurementImplications":"Interpretation: Demand reproducibility, data lineage and annotation validation from analytics suppliers; prohibit unsupported causal performance guarantees.","operatingModelImplications":"Interpretation: Institutional research owns inference; faculty governance owns assessment changes.
