Gateway Christian School was established in 1974 as a ministry of Gateway Church with the goal of training Christian leaders by providing an excellent academic program while teaching the principles of life from God's Word.
Our prayer is that students will graduate from GCS with a personal relationship with Jesus Christ, with academic preparation to enter college, and with the character and skills to impact their world for Christ.
We believe strongly in the local church and family. God has given children to parents, and we serve to help parents fulfill their responsibility in training and nurturing their children.
Being actively involved in a local church is a requirement for each family/student.
We believe that the home, the church, and the school are vital in training the next generation for Jesus Christ.
GCS is annually recognized as a Model School by Accelerated Christian Education.
