The history of Credo Christian High School reaches back to a meeting in November 1951 suggesting the need for Reformed Education. Many meetings later and after much labour of love, William of Orange Christian School opened its doors on September 5th, 1955 with an enrollment of 58 students in grades 1 through 8. After considerable growth and numerous expansions the membership at a meeting in June 1971 adopted a motion to start a junior high school. In September 1973, this decision was implemented. Mr. S. VanderPloeg became the principal of the Junior High. In 1974, grade 9 was added and in 1975 grade 10 was added to complete the junior high grades. In 1977 the board was asked to investigate the possibility of adding grades 11 and 12. The consideration to add grades 11 and 12 prompted a decision to establish a high school in a separate building as a joint venture with the Abbotsford society (which operated the John Calvin School in Yarrow). Grades 8, 9 and 10 students, along with a newly formed grade 11 class, moved into rented facilities (from the Vancouver Bible College in Surrey) and started a new academic year in September 1978 under the name William of Orange Secondary School. In 1979 grade 12 was added and in June of 1980 the first graduating class of the combined schools was presented. In September 1980 the staff and students moved into new facilities on 52nd Avenue in Langley. The name was changed to Langley Christian High School, and then later on it was again renamed to Credo Christian High School. The following year the completed building was dedicated and so the work of teaching and learning took on a new sense of permanence. Enrolment at Credo Christian High school continued to climb. Staff were added and soon it was recognized that more programs were required to meet the needs of all the students. In May 1985 the membership approved a building expansion to include an Industrial Education shop, additional classroom, office and storage for an I.E. program. Through the generous support of Ladies auxiliaries, an extensive Industrial Education and Home Economics program was started in September 1985. At a membership meeting in October 1989 unanimous approval was given to proceed with a building program to add eight classrooms (to include new science labs, music room, and art room) as well as additional Physical Education change rooms.more...See more text
