Analysis
At first glance, SIU-Carbondale's Zoology program appears troubled—starting salaries of $23,366 rank in just the 5th percentile nationally. But context reveals a more nuanced story. With only two schools offering this program in Illinois, the state comparison is limited, though SIU sits at the 60th percentile statewide. More importantly, earnings jump 51% to $35,205 by year four, substantially outpacing the typical trajectory for this field and bringing graduates closer to competitive standing.
The debt picture is reasonable: $21,717 is below the national median for zoology programs and represents less than one year's starting salary. Given SIU's 90% admission rate and that over a third of students receive Pell grants, this accessibility matters. For students passionate about animal biology who need an affordable entry point to the field, the manageable debt and strong earnings growth create a viable path forward.
The challenge is surviving those first few years financially. Parents should know their child will likely need supplemental support or a side job early on, as $23,366 won't cover independent living in most areas. If your student is committed to animal biology and willing to push through a difficult first year or two for better prospects down the road, this program works. If they need immediate financial independence after graduation, they should seriously reconsider this major regardless of the school.
