This report contains the typology of charter schools that were sought, based on Carpenter's careful sorting of 1,182 charter schools, representing 87 percent of all those operating in 2001-2002 in the five states (Arizona, California, Florida, Michigan, and Texas) that then accounted for the lion's share of U.S. charter schools. Carpenter sorted the schools into 55 categories, then grouped those into ten larger categories. He shows how many schools are in each, then provides some fascinating average data about the kinds of kids they enroll, how big they are, how old they are, etc. This report is simply the "typology" report. The following is appended: Charter School Typology with Distribution by Instructional Sub-Types. (Contains 4 figures.) [Foreword for "Playing to Type?
