By  | 

Cost, curriculum, and campus amenities all matter when you’re choosing a college. So do job placement rates, faculty, average class size, and many other factors. But future freshmen and their parents might overlook one of the most valuable things a college has to offer: its alumni Networks.

A vibrant network of graduates can be a resource long after you leave campus in terms of networking opportunities, connections to mentors and other professionals, and even news about jobs.

So what makes for a great alumni Networks? You want a group that’s engaged and willing to lend a hand to fellow alums. Location matters, too, as does your chosen career. Some networks might be especially strong in certain parts of the country or in certain fields. And then there are sheer numbers.
