- Attracting substantial philanthropic support, CMO schools have grown rapidly from encompassing about 6 percent of all charter schools in 2000 to about 17 percent of a much larger number of charter schools by 2009 (Miron 2010).
- CMOs represent approximately 20 percent of the approximately 5,000 charter schools operating nationally, up from 12 percent in 1999.
- About 80 percent of all CMO-run schools operate in Texas, California, Arizona, and Ohio.
- About 74 percent of all CMO schools eligible for our study are located in cities.
- Compared to their host districts, the middle school student population served by the average CMO in our study includes a greater percentage of minority and low-income students.
- CMO charter school principals report that their teachers receive more coaching and are more likely to be paid based on performance.
- Like public charter schools as a whole, the report finds that student achievement results are mixed with findings going both positive and negative. Keep in mind that the types of schools and educational programs also vary significantly.
As the trend continues to be on replicating systems that have already demonstrated success, research such as this study will provide helpful information to charter school authorizers that are considering whether or not to approve new charter schools.
