This study of the “scalability” of no-excuses charter schools was written by Steven Wilson, who is a supporter of this approach.
The no-excuses teachers agree that test scores are the most important outcome of schooling and the best preparation for college readiness.
He examined the education backgrounds of the teachers in several very successful charter schools in Boston.
83% were graduates of very selective colleges.
These teachers typically work 9-10 hours daily and are on call at any time to assist with homework.
They burn out and leave with frequency, because of the demands of the job and because they have other career ambitions.
This made him wonder about the scalability of the model.
To scale up to have a significant effect, he found, would require that half the graduates of elite universities enter teaching for at least two years, which doesn’t seem realistic.
He assumes that anyone who graduates from a selective college or university will make a better teacher.
Given the limited supply of elite graduates, he concludes that what is needed is tight and specific instructional systems, like the one he is involved in.
