While past annual "Profiles" reports have focused on either for-profit EMOs (education management organizations) or nonprofit EMOs, this is the first annual "Profiles" report to cover both categories in a single report which allows for easier comparisons. The 2010-2011 school year marked another year of relatively slow growth in the for-profit education management industry and another year of steady growth in the nonprofit EMO industry. The authors believe their key finding from the past three years, that the for-profit school management sector has leveled off and that many for-profit companies are expanding into supplemental services, continued in the 2010- 2011 school year. The nonprofit management sector's growth remains steady, both in terms of new nonprofit EMOs and new managed schools. While the number of new schools under for-profit EMO management has slowed, enrollments in all managed schools continue to grow at a rapid pace. Appended are: (1) Reader's Guide; (2) State Resources Table; (3) For-Profit EMO Response Table; (4) Nonprofit EMO Response Table; (5) No Longer Profiled Companies; and (6) Methods for Compiling School Profiles.
