The Carroll School of Management is in the midst of an impressive jump in the Bloomberg BusinessWeek biennial rankings of the nation’s best part-time MBA programs. The Carroll School evening MBA program rose from 53rd to 32nd place in the most recent rankings, which were released last week.

What’s the main reason for the 21-place leap?

“We were awarded grades of A-plus for Teaching Quality and Curriculum, and A for Caliber of Students,” says Jeffrey L. Ringuest, associate dean of graduate programs for the Carroll School. “These high scores reflect the hard work of our faculty and staff, and the high quality of our students. We are very pleased that the Bloomberg BusinessWeek ranking of our MBA program has risen to 32.”

The new ranking now means the Carroll School has the top-rated part-time MBA program in Boston, ahead of Babson College (now ranked 34th) and Boston University (44th). Worcester Polytechnic Institute has the region’s top-rated part-time program at 16th, while UMass-Amherst is now at 66.

Nationally, Carnegie Mellon University’s Tepper School of Business is the top part-time MBA program, followed by UC Berkeley’s Haas School of Business, the Southern Methodist University Cox School of Business, UCLA’s Anderson School of Business, and the Love School of Business at Elon University.
