Graduating on time

By student background (4 years)

On-campus criminal offenses reported under the Clery Act, 2022–2024, across 4 campuses (7,603 students). Counts reflect reports, not convictions — schools with strong reporting cultures often show more, so a higher count doesn't simply mean a more dangerous campus.

Reported offenses in an average year

The same 2022–2024 Clery Act reports, divided down to one year.

Averages, not a forecast — a single year can run well above or below this. Bars are scaled against this campus's most-reported offense, so they compare types here rather than against other schools.

What you'll actually pay, by family income

Average net price (total cost minus grants and scholarships) paid by aided students in each family-income band.

College Scorecard / IPEDS, most recent year. Family income is total household income; net price covers tuition, fees, room, board and supplies after grant aid, for students receiving federal aid.

Four-year (or more) true cost

Net price for your family's income, projected across the time it actually takes students here to graduate.

$28,681/year × about 4.2 years — most students here don't finish in exactly four, and each extra term adds cost. A planning estimate from net-price and graduation-timing data, not a bill.
