Fordham Foundation says “yes.” Here’s the new study and here are the “takeaways:”

•    Board members, by and large, possess accurate information about their districts when it comes to finance, teacher pay, collective bargaining, and class size. Whether they were knowledgeable from the outset or surround themselves with savvy staff and administrators, many are making decisions from an informed point of view.
•    But such knowledge is not uniformly distributed. Surprisingly, members who were never educators themselves are more accurately informed than their peers who once were (or still are) educators. Likewise, political moderates appear to have more accurate knowledge than their liberal or conservative counterparts.
•    A district’s success in “beating the odds” academically is related to board members’ focus on the improvement of academics. Unfortunately, not all board members have this focus.
•    Board members elected during on-cycle, at-large elections are more likely to serve in districts that “beat the odds” than those chosen by voters off-cycle or by ward. In some localities, how board members are elected may deter the best and brightest from taking on these key roles.
