The state’s four-year colleges and universities opposed a two-year college’s proposed business degree, citing program duplication. Experts say that’s the wrong argument. About half of all U.S. states now allow at least some of their community colleges to offer baccalaureate degrees. But proposals to expand the number of those programs aren’t without controversy, given that leaders of two-year institutions and their four-year peers tend to view the need for such programs very differently.
