In one tuition comparison example, what was the annual savings generated by in-state residency status versus out-of-state tuition?

$20,000 annually

The financial advantage conferred by residency status at public universities is substantial, serving as a critical factor in STEM education planning. In a specific illustration provided, a public school charging $12,000 for in-state tuition and $32,000 for out-of-state tuition yielded an annual difference of $20,000 saved for the resident student. This yearly saving accumulates significantly over the standard academic duration; the total residency discount over four years amounts to $80,000. This difference often exceeds the entire cost of tuition at certain highly affordable private or in-state schools for the same four-year period, highlighting residency as a major financial lever.
