how you're pulling for -- i know that we're really limited also on the number of candidates for principalships. if you can speak to that a little bit? >> just for clarification, terms of leadership recruitment, we have a couple of principals who have long tenures at their current school site. so maybe reassigning them or reappointing them? >> not necessarily. they continue to stay strong. there have also been sites that have had some turnover and are not doing nearly as well so i'm just wondering what the focus is going to be to recruit the strong principals to do some more shared leadership or mentoring. anything we can do to help the other sites. first of all, when you say middle school some people have a lot of different reactions. some would say yes, i'm there for middle schools. some will kind of run away from me. so you get a lot of different reactions, but one thing that has been really effective the last year and a half is that our middle school principals are part of an equity center of professional learning community. the work of this p.l.c. or ecplc has been really, really powerful.
