This report documents a study of charter schools in Alberta, Canada. The purpose of the study was to examine the academic achievement of the 10 charter schools in the province. Data were collected from test scores in language arts, math, science, and social studies of third-, sixth-, and ninth-graders; reviews of various documents; and interviews with administrators at each school. Following are some of the key findings: Overall, students in most of the schools appeared to be performing very well on standardized achievement tests. The majority of students scored above the provincial average in all tested subjects at all grade levels. All the charter schools in the study had adopted or developed ways of measuring progress or achievement other than the provincial achievement tests. As centers of innovation, charters schools have been very successful. The report makes, among others, the following recommendations: Charter schools should use systemic assessments separate from the provincial achievement tests. Structures must be put in place whereby information regarding the practices and innovations being used in the charter schools are shared systematically with the public, separate school systems, and the general community.
