ANOMALY ENGINE · NOTABLE SIGNALS
What the data flags at Diablo Valley 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.

CAUSAL DISCIPLINE
“Diablo Valley College graduates earn $X” — not “Diablo Valley College makes you earn $X”
Median earnings describe what cohorts earned. They do not describe what attending Diablo Valley 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.
