Clairbourn School has a fine tradition of educational achievement since 1926. During the school year, it enrolls 428 students in grades Nursery through Eight on 8 tree-filled acres in the San Gabriel Valley. Clairbourn's summer programs serve more than 350 students annually.

At Clairbourn, the needs and success of each child are the central concerns. In both its summer programs and during the regular school year, Clairbourn offers a rich diversity of educational experiences in line with current professional teaching practices.

Our goal is to assure that, without using undue pressure, each child is challenged to grow and develop his or her own special strengths and interests, to achieve a high level of competency in the essential skills and areas of knowledge, and to enter adulthood with confidence and high expectations.

The Early Childhood Department covers children in the 3-year olds' program, 4-year olds' Pre-kindergarten program and Kindergarten.

The Elementary School grades are divided into the 1st/2nd grade department and the 3rd/4th/5th grade department.

The Middle School covers the 6th/7th/8th grades.
