The New York Times did a story on the growing trend of public universities charging higher tuition for degrees in lucrative fields such as business and engineering. This practice brings up many issues including price sensitivity for poor students who may stay away from majoring in business. Some worry that students who are charged more for their major will stick to the courses in their field to feel that they are getting their money’s worth. Many are concerned that public universities have disregarded the premise that a well-rounded higher education is for the common good of society. Private universities who are not faced with the same budget constraints are avoiding differential pricing.

Starting this fall, juniors and seniors pursuing an undergraduate major in the business school at the University of Wisconsin, Madison, will pay $500 more each semester than classmates. The University of Nebraska last year began charging engineering students a $40 premium for each hour of class credit.

And Arizona State University this fall will phase in for upperclassmen in the journalism school a $250 per semester charge above the basic $2,411 tuition for in-state students.

Such moves are being driven by the high salaries commanded by professors in certain fields, the expense of specialized equipment and the difficulties of getting state legislatures to approve general tuition increases, university officials say.

“It is something of a trend,” said Barmak Nassirian, associate executive director of the American Association of Collegiate Registrars and Admissions Officers.

Even as they embrace such pricing, many officials acknowledge they are queasy about a practice that appears to value one discipline over another or that could result in lower-income students clustering in less expensive fields.

“This is not the preferred way to do this,” said Patrick V. Farrell, provost at the University of Wisconsin, Madison. “If we were able to raise resources uniformly across the campus, that would be a preferred move. But with our current situation, it doesn’t seem to us that that’s possible.”
