What the data flags at Joliet Junior College
Short-arc shifts (recent 3-year window), peer outliers, earnings trend breaks, completion drops, enrollment cliffs, and debt-to-earnings warnings — surfaced deterministically from the federal record. Multi-decade shifts are reported separately in the Long Arc section, since 25-year tuition drift isn't really an anomaly.

How earnings spread, 4 to 10 years after entry
Treasury tax-record earnings for federally aided students who first enrolled at this institution. Each point is a horizon from the most-recent vintage. Single median per horizon (no p25/p75 publishing).
Earnings widen with time post-entry. Selection: federal-aid recipients only — not all graduates.Methodology →
SECTION 03 · DEBT-TO-EARNINGS
What loans cost relative to earnings
Annual debt service as a share of median earnings 10 years after entry, computed under federal Direct loan terms (10-year fixed at 6%). The 8% line is the gainful-employment threshold from federal regulation; above 12% has historically been considered “failing” under prior rule cycles.

CAUSAL DISCIPLINE
“Joliet Junior College graduates earn $X” — not “Joliet Junior College makes you earn $X”
Median earnings describe what cohorts earned. They do not describe what attending Joliet Junior College caused. Selection effects (who admits, who enrolls, who completes) are real. We publish federal data with strict descriptive phrasing — and link the methodology where you can read about the limitations directly.
