Biology at Illinois State University
Bachelor's Degree
Analysis
Illinois State's biology program outperforms three-quarters of similar programs nationally, with graduates earning $36,337 in their first year—well above both the national median ($32,316) and Illinois median ($32,844). While it doesn't match the top biology programs in Illinois like Governors State, it ranks solidly in the 60th percentile statewide and shows exactly the earning trajectory parents hope to see: 35% income growth by year four, reaching nearly $49,000. The debt load of $24,672 stays below both state and national medians, creating a manageable 0.68 debt-to-earnings ratio that most graduates can handle.
The real story here is trajectory. Many biology graduates struggle with stagnant wages in lab tech or research assistant roles, but Illinois State grads demonstrate clear progression into better-paying positions. This matters enormously for a degree that often serves as a stepping stone to graduate school or professional programs—students who need to work a few years before applying to medical or graduate school aren't stuck in low-wage holding patterns.
For families concerned about biology being a risky major, this program delivers substantially better outcomes than typical. With an 89% admission rate and reasonable debt burden, it provides accessible entry to a biology degree that actually translates to above-average earnings, both immediately and over time. Parents should feel confident their investment will support either workforce entry or graduate school funding.
