Tri-City Adventist School is a Kindergarten through 10th grade Christian school, which exists to develop spiritual ideals in its students.
The ultimate objective of Christian education is the development of character.
We encourage forming good habits through self-discipline governed by Christian principles.
The school was originally formed in 1962 to offer Christian education to the Tri-City area.
It is supported by three local Seventh-day Adventist churches--Pasco Riverview SDA Church, Richland SDA Church, and Kennewick SDA Church.
Even though TCAS has been established primarily for Seventh-day Adventist families, enrollment is open to others who support the philosophy and objectives of Seventh-day Adventist Christian education.
