Open Quote My Children were late starting school do to situations beyond our control, so they started at a lower grade for their age group. Cinnabar never hesitated to help get them started and placed them in the appropriate grades that were needed for each of my children. None of the staff or teachers ever looked down at my children or myself and have been very supportive to us and made me feel just as important and appreciated as all the other parents and kids. they have been a real help for us, and I know my children are safe and learning to the best of their abilities, with room to grow at the right pace. I strongly recommend Cinnabar School to EVERYONE I know who have children. Close Quote

About Student-Teacher Ratio
Student/teacher ratio is calculated by dividing the total number of students by the total number of full-time equivalent teachers. Please note that a smaller student/teacher ratio does not necessarily translate to smaller class size. In some instances, schools hire teachers part time, and some teachers are hired for specialized instruction with very small class sizes. These and other factors contribute to the student/teacher ratio. Note: For private schools, Student/teacher ratio may not include Pre-Kindergarten.
