SESI was founded as the need arose for specialized education programs that could be successful for students, cost effective, and easy for public schools to administer. With these guidelines in mind we set about designing our programs. The result is High Road Schools, High Road Academies and the Sierra Schools. Since the beginning of our first school to now, the company's mission and the unique SESI instructional model has never wavered. Building on our success with the most difficult-to-educate students, SESI currently provides services to thousands of children, in 42 schools, in 9 states and the District of Columbia.
