WOS-000353148000008	Chingos, MM	The Uneven Performance of Arizona's Charter Schools	2015		.txt	text/plain	120	4	52	Using student-level data covering all Arizona students from 2006 to 2012, we find that the performance of charter schools in Arizona in improving student achievement varies widely, and more so than that of traditional public schools (TPS). Arizona enrolls a larger share of its students in charter schools than any other state in the country, but no comprehensive examination exists of the impact of those schools on student achievement.	cache/WOS-000353148000008.txt	txt/WOS-000353148000008.txt
