Methodology & source manifest
Everything on the Department of Education monitor derives from public records — the ED FY2027 Budget Summary, OMB's Historical Tables, the USAspending API, and the ED Office of Inspector General / KPMG audit reports and GAO oversight documents. This page is the audit trail: method, sources, validation, and every flag.
Method
Discretionary vs. mandatory loan accounts
The cardinal rule for Education. The DISCRETIONARY appropriation (Title I, IDEA, the discretionary Pell appropriation, and the rest) is what Congress sets each year and what this monitor reconciles to the dollar. The MANDATORY side is the William D. Ford Direct Loan and related credit accounts (FFEL, mandatory Pell, TEACH, and the negative General Fund Receipts re-estimate line), whose budget authority swings by hundreds of billions year to year because of Federal Credit Reform Act subsidy re-estimates— accounting adjustments to the cost of past lending, not program funding. The two frames are reported separately and never summed into a single “Education budget” figure. Note that Pell moves in two directions at once: the discretionary Pell appropriation rises while mandatory Pell falls — read together, not netted blindly.
The discretionary reconciliation
The discretionary spine is the FY2027 Budget Summary's Detailed Budget Table by Program (Appendix, pp. 59–69). Every program area's appropriation sums, to the dollar per fiscal year, to the published Total Discretionary Appropriation ($78,761,810K FY25 final / $75,742,582K FY27 request) — asserted at build time. Separately, the components of the −$151.4B General Fund Receipts re-estimate line are validated to the published line to the dollar. The source carries no per-program FY2026 column, so FY2026 is OMITTED at the program level; the department-level FY2026 discretionary figure (~$78.9B) is back-computed from the document's narrative and carried as flagged context only, never inserted into a row.
Source documents & validation ledger
The history layer is shown in nominal dollars only — OMB Historical Table 5.2 publishes no constant-dollar basis, and no deflator is synthesized; the negative FY2023 value is a real downward loan re-estimate, retained not suppressed. ED was created from HEW in 1980, so the budget-authority series begins there; pre-1980 HEW years are not comparable and are excluded, not fabricated. The audit layer carries the three consecutive disclaimers (FY2022–FY2024) and their single loan-portfolio root cause explicitly — the inverse of the clean-streak agencies, and the audit-side evidence for keeping the loan accounts strictly separate.
