Early in 1996, various alumni from all classes gathered to discuss the upcoming centennial of Colville High School. Those in attendance scheduled June 20, 21 and 22 of 1997 to host this momentous occasion. Alumni from the various classes mobilized to gather the names and address from their respective classes and invitations were sent out to all.

The planning process included commemorative sweatshirts, caps, and bricks to be sold with the alumni's name and graduation date to be installed on the Centennial Wall. Other committees worked the selection of distinguished alumni and an assembly to honor them. Memberships were also sold at the event to help defray expenses. A dance was also scheduled to round out the occasion.

The centennial held in June of 1997 was considered a resounding success. Over 1200 alumni participated in the three day celebration. Proceeds from the brick sales, clothing items and memberships totaled close to $12,000 after all expenses were paid.

In the fall of 1997, a meeting was held and it was decided the Colville High School Alumni Association would become it's own entity complete with by-laws, officers and a separate bank account to be responsible for their own monies.
