Collegiate is divided into Lower School (Kindergarten-Grade 4), Middle School (Grades 5-8), and Upper School (Grades 9-12). Each division has its own administrative head and core faculty. Many faculty members teach in more than one division of the school. The students and faculty enjoy the advantages of a small-school environment while benefiting from the stimulation a college preparatory school can provide. The atmosphere at Collegiate is shaped by the interaction of the student body and a sense of community within the school.
