I just read an interesting (and very short) piece in the latest Teacher's College Record. In it, Tom Carroll and Souma Sathya argue that we need to "change the conditions that make high-needs schools hard to staff" (which is also the title).
Their most important point, to me, is "that at the end of the day it will be the teachers who will make the decisions about where they will teach." As such, they argue that we should make high-needs schools more attractive to teachers.
Their recommendations are, in short, that we award bonuses to teachers who teach in these schools, ensure that there are competent and supportive leaders, that novices are not left to "sink or swim," and that paths to rise from novice to master teacher be created.
The purpose of this post is to encourage you to read the piece (it will only take two minutes, really), so I'll keep the analysis short. Though short on details, all of the recommendations seem logical and fairly straightforward. High teacher turnover certainly crippled my school and given the demographics of the current teaching force it seems likely both that reducing turnover in the future will benefit high-poverty schools and that making schools better places to work will reduce turnover.
