Geological and Earth Sciences/Geosciences at Illinois State University
Bachelor's Degree
illinoisstate.eduAnalysis
A debt load near $25,000 against first-year earnings around $40,000 creates a manageable 0.62 ratio that falls within acceptable parameters for a STEM-adjacent field. Based on comparable geosciences programs nationally, graduates can expect to carry debt equal to about seven months of income—not insignificant, but workable. The challenge is that these estimates suggest Illinois State's outcomes likely mirror the national median rather than exceed it, meaning your student won't be at a particular advantage or disadvantage compared to most geology programs across the country.
The concerning part is the broader context in Illinois. Looking at reported data from similar programs statewide, top-tier options like UIUC and UIC show first-year earnings in the $37,000-$39,000 range—essentially the same as what peer programs suggest for Illinois State. In geology, where fieldwork opportunities, faculty research connections, and industry partnerships can significantly impact job placement, attending a program with limited outcome visibility means you're betting on comparable quality without clear evidence. The wide accessibility (89% admission rate) suggests Illinois State casts a broad net, which may mean less selective cohort quality and potentially fewer high-achieving peers pushing each other toward competitive positions.
If your child is passionate about geology and ISU offers specific research opportunities or faculty expertise they value, the estimated financial picture isn't prohibitive. But without actual outcome data distinguishing this program from the pack, you're essentially paying for an average result in a field where connections and program reputation matter considerably.

About This Data
Source: U.S. Department of Education College Scorecard (October 2025 release)
Population: Graduates who received federal financial aid (Title IV grants or loans). At Illinois State University, approximately 30% of students receive Pell grants. Students who did not receive federal aid are not included in these figures.
Earnings: Median earnings from IRS W-2 data for graduates who are employed and not enrolled in further education, measured 1 year after completion. Earnings are pre-tax and include wages, salaries, and self-employment income.
Debt: Median cumulative federal loan debt at graduation. Does not include private loans or Parent PLUS loans borrowed on behalf of students.
Estimated Earnings: Actual earnings data is not available for this program (typically due to privacy thresholds when fewer than 30 graduates reported earnings). The estimate shown is based on the national median of 103 similar programs. Actual outcomes may vary.
