The presidents of Montgomery College and the University of Maryland, College Park, signed an agreement Wednesday that officials say will help local biotechnology companies find more recruits in a burgeoning industry.The agreement sets the stage for allowing students to take four years of coursework for biotechnology programs at the Montgomery College-Germantown Campus but earn a bachelor’s degree in life sciences from the University of Maryland. The Universities at Shady Grove in Rockville, run by the University of Maryland, would provide services for students in the program.
