Sweet Briar College has managed so far to stave off financial insolvency and its planned 2015 closing — though it took four different lawsuits, a mediation agreement and the replacement of its board and president to reopen the campus for the 2015-16 school year. Daunting challenges remain, and early estimates of enrollment for 2015-16 (down to less than 300 from 530 last year) make the need for short- and long-term planning acute.
