Tip
Use CTREE Slides for a presentation-ready walkthrough of the dashboard results. The deck opens in the browser, advances with the arrow keys or space bar, and links each major figure back to the standalone chart.
Note
Preliminary working dashboard built from the CTREE working data snapshot refreshed on May 28, 2026. The snapshot is still stored in outputs/ctree_2026/data_freeze_2026-05-16 for path stability. Simon’s wide-net rule applies: approved/future and legacy/deceased programs remain included when evidence supports the program, but are flagged rather than treated as ordinary active programs. Purely co-curricular centers, fellowships, initiatives, and related ecosystem records are tracked on the ecosystem dashboard rather than counted as undergraduate programs here.

Requirements Coverage
How much of the curriculum is currently coded across the included sample?
Economics Requirements
Economics requirement rates are computed only over course-coded programs. Programs with partial or existence-only collection are treated as missing here, not as requiring zero economics.
Disciplinary Balance
Each program’s required courses are assigned to one of three disciplinary vertices — Economics (E), Politics / Law (P), and Philosophy (Φ) — under a strict mapping that excludes integrative courses (civics, multi- disciplinary, PPE gateway courses) from the denominator. Programs with at least three clearly-classified required courses are classifiable and plotted here; the remainder are noted below. See analysis/simplex/SIMPLEX_PLAN.md for the full methodology.
Note
Provisional analysis. The discipline mapping is pending co-author review. The integrative-course fractional allocation (Tier 2) requires sign-off before use. Only the strict Tier 1 coordinates are shown here.
| Category | Classifiable | Low coverage | Unclassifiable |
|---|---|---|---|
| Civic thought / leadership | 38 | 39 | 89 |
| PPE | 81 | 2 | 1 |
| Political economy | 74 | 8 | 2 |

The dashboard is intentionally conservative about curricular conclusions: missing course requirements remain missing. The next analysis pass should decide whether to restrict economics-requirement rates to course-coded programs only, report both denominators, or model missingness directly.
