nbauman,
I agree with you. A study was done once to see what two factors had the strongest association with higher test scores. With the one factor being test scores/performance the other factors were: education of teacher, amount of homework, length of school day, experience of teacher, and family income. The strongest predictor was family income.
The way the system is set up now, the new teacher's will be placed in the lowest performing schools. Low performing schools will have a large percentage of low income parents. Ergo, new teachers will be most likely to be let go because there students are not performing well. This is designed to fail the students and aspiring new teachers.
This ruling alone will not solve the troubles we have in education. The way it is done is backwards, the most difficult assignments should be given to the most experienced teachers. There are a few other professions, usually government based, that have this backwards way of assigning jobs.
