Analysis
Sonoma State's geoscience program sits at a challenging crossroads. Based on comparable bachelor's programs across California, graduates typically start around $40,000—roughly matching the national median but landing well behind California's top programs, where Cal Poly SLO and Pomona graduates earn nearly $50,000. The estimated debt load of $17,900 creates a manageable 0.45 debt-to-earnings ratio, significantly better than the national median debt of $24,757 for this field. That lower borrowing matters for a field where entry-level salaries don't provide much cushion.
The real question is trajectory. Geosciences can lead to solid careers in environmental consulting, resource management, or energy sectors—fields where California's regulatory environment and natural resources create genuine demand. But first-year earnings in the low $40,000s in one of the nation's most expensive states leave little room for error. The gap between Sonoma State and the state's stronger programs suggests differences in either curriculum strength, alumni networks, or regional employer preferences that could affect both immediate job prospects and longer-term earning potential.
With these figures drawn from peer programs rather than Sonoma State's actual outcomes, you're operating with limited visibility. If your child is passionate about earth sciences and committed to the Bay Area, the relatively modest debt provides some safety. But investigate what makes graduates from programs like Cal Poly or UC Davis command 20% higher starting salaries—and whether Sonoma State offers comparable pathways into those same opportunities.

Population: Graduates who received federal financial aid (Title IV grants or loans). At Sonoma State University, approximately 36% 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 median of 10 similar programs in CA. Actual outcomes may vary.
