LINCOLN, Neb. (AP) — A tuition increase that only University of Nebraska-Lincoln business and engineering students pay hasn’t swayed students from choosing those majors.

The $50-per-credit hour increase, known as differential tuition, has generated millions in revenue that’s helped employ additional faculty, renovate facilities and expand student services at the school.

The schools’ College of Business Administration and College of Engineering are continuing to expand.

Students enrolled in either program pay an extra $3,000 over their time at the university. However, those students also usually graduate and are employed at jobs with higher earning potential than students in other programs.
