Holding Teachers Hostage to Demogaphics

The field of education has become a political hot button topic again, notably over failing schools, charter schools, and how best to hold teachers accountable for the job they do. I'm not going to go into this topic too much right now (I have teachery things of my own to do) but I did want to point this little tid bit out.

I'm not all that familiar with Rochester, NY, but I do know it is a urban/suburban area with multiple high schools. Here are the results of two such schools, Brighton and Thomas Jefferson. (information found at www.greatschools.org)

The real kicker?
Brighton:
Total per pupil expenditures $14,834

That's roughly $1,500 under the state average.

Thomas Jefferson:
Total per pupil expenditures $15,732


(I said I wasn't going to go into this much, not that you wouldn't).

There are some differences between teacher quality and classroom size in these schools but not enough to cause the results to be this drastically different. I think the biggest influence on kids concerning their education is always going to be at home. Brighton can spend less per student and achieve far greater results because the home environment is that much better off for those Thomas Jefferson students (as noted by the students eligible for reduced or free lunch). The short of it is, the teacher in the classroom can do almost nothing about this. Holding teachers accountable for the final grades of their students is wrong in epistemological terms and further reduces a teacher's willingness to work in poorer school districts.

I don't have time to come up with a better system right now (topic for another day, perhaps). Teachers certainly need to be held accountable, as any public employee does, but the method of using students' scores as a true measure of the teacher's quality is inaccurate because different teachers will begin the year with students with different abilities. The answer will almost certainly have to come from within the community as only they will know the students well enough to know if they show improvement, which may be a better goal than an arbitrary passing number.
