Member Testimonials

The ACSI accreditation process was very helpful. It helped make our program better. Thank you.
Mary Sue Hale, Cross of Hope Lutheran Preschool

ACSI is a blessing in so many ways. It is far and away the finest professional encouragement to our faculty and administrative team. We are so blessed to have ACSI and we know it.
Bruce D. Johnson, Redwood Christian Schools

I am very happy with our affiliation with ACSI. We're a smaller school, and ACSI offers events and suggestions that are doable for us. We are never made to feel unimportant because we are not a large school.

Head Bangers

We have a toddler that bangs his head on the floor when he gets frustrated. He hits his head so hard he is now leaving marks. Of course we stop it but not always quick enough. Do you have any suggestions for this issue?

Pray for Christian schools and colleges in Canada

Please pray for a favorable ruling by the Canadia Supreme Court regarding Trinity Western University's right to have a Law School. Their Code of Conduct is being used against them, since they ask student to abide by biblical teachings regarding sexual activity.
