Eis uma interessante conclusão de um artigo sobre escolas públicas e escolas “charter” (alguma boa tradução?):
This paper explores differences in technical efficiency between traditional public schools and both profit and non-profit charter schools using a stochastic frontier model. We find that administration spending tends to have a negative effect on test scores, while classroom spending tends to have a positive effect on test scores. Spending on support services or supplies had little effect on test scores. More experienced teachers tended to increase efficiency, while minority percentage tended to decrease efficiency.
