The Canadian Reformed School Association of Langley, Inc., operating the Credo Christian Elementary School, is an 'offshoot' of the Canadian Reformed School Association of Surrey, B.C. The latter Association was founded in 1951 with the aim of building a school which would offer Reformed education.  On Sept. 5, 1955 the Canadian Reformed School (Burnaby) was officially opened, having an enrolment of 58 pupils in 8 grades, divided between 2 classrooms.  The name "William of Orange Christian School" (WOCS) was officially adopted in 1956.  

A new four-room school building was constructed in 1962.  By 1966, more than 100 pupils were enrolled.  In 1974 a new school building, with 8 classrooms, a library, and a science room, was opened in Cloverdale.

 Due to rapid growth in the Langley area and WOCS bursting at the seams, (about 300 students) it was decided to build and operate a second school in Langley.

 This school was officially opened in 1986.  The new building was erected on 52nd Avenue east of 216 Street and was named Credo Christian Elementary School (CCES).  By 1989, the Langley Canadian Reformed School Society separated from its 'parent' Surrey Canadian Reformed School Society to operate the Credo Christian Elementary School on its own.

 For many years, and with a few additions and other modifications made to the building, CCES operated smoothly. In the fall of 2021 a significant change occurred when WOCS closed its doors due to declining enrollment and most of the WOCS families migrated to CCES. In addition to this influx of students, Middle Schools (Grades 6 – 8) were established on the elementary campuses of both CCES and John Calvin Christian School (Yarrow). The consequence is that currently at CCES we have a very full building. Additionally, as Grade 8 has been added to our campus, we now usually speak of Credo Christian School (CCS) rather than Credo Christian Elementary School.
