As state support lags, tuition rises. Itâ??s a well established phenomenon. But whatâ??s less discussed is the effect that flat state support might be having on the traditional undergraduate tuition model itself. The one-student, one-rate model is somewhat silently slipping away at many public universities nationwide, as institutions increasingly turn toward differential (read: higher) tuition rates for students pursuing specific majors, often those with higher costs of operation.
