Microbiological Sciences and Immunology at California Polytechnic State University-San Luis Obispo
Bachelor's Degree
calpoly.eduAnalysis
Cal Poly SLO's microbiology program produces earnings that crush the national average—$55,807 versus $38,040 nationally—placing graduates in the 95th percentile nationwide. But here's the interesting wrinkle: within California's more competitive landscape, this performance lands at the 60th percentile, essentially matching San Francisco State and trailing only UC Berkeley by a few thousand dollars. For a program at a selective public university (30% admission rate), that's solid positioning against some of the state's flagship institutions.
The debt picture looks reasonable at first glance—$22,138 is close to the national median—but California programs typically carry less debt (state median: $14,904), meaning Cal Poly graduates emerge with about $7,000 more than their in-state peers. Still, the 0.40 debt-to-earnings ratio means graduates can expect to earn more than double their debt in their first year, giving them financial breathing room early in their careers.
One major caveat: this data comes from fewer than 30 graduates, so these numbers could shift significantly year to year. That said, the strong first-year earnings suggest the program's rigorous, hands-on approach is translating to real market value. For families comparing California options, this program delivers competitive outcomes at what's likely a more affordable price point than UC Berkeley, though you'll want to confirm that final costs after aid align with your budget.
