Association of Christian Schools International

What Association of Christian Schools International does

Association of Christian Schools International (ACSI), founded in 1978 and headquartered in Colorado Springs, Colorado, is a 501(c)(3) nonprofit membership association and the largest evangelical Christian school association in the world. It serves more than 25,000 schools across 108 countries, reaching over 5.5 million students, and operates with 101-250 employees through a global network of regional offices. Its mission centers on strengthening Christian schools and equipping Christian educators through an integrated portfolio of accreditation, teacher and administrator certification, curriculum publishing via its wholly-owned Purposeful Design Publications subsidiary, student assessment programs, professional development events, public policy advocacy, and student leadership programs.

The organization monetizes through six primary revenue streams: recurring membership dues from schools and educators; transactional curriculum and textbook sales through Purposeful Design Publications; recurring accreditation and certification fees; one-time event registration (with pricing ranging from free webinars to $625 for ICEC Europe 2027 non-member rates); usage-based assessment services (Iowa Assessments Suite, ESGI, ACT District Testing, Flourishing School Culture Instrument); and managed-services revenue from the Children's Tuition Fund, a wholly-owned ministry positioned to facilitate Federal Tax Credit Scholarships launching January 2027. GTM is hybrid: sales-led membership enrollment combined with event-driven engagement (ICEC, Leadership Conference, PPA Summit, Rooted Summit, Early Education Innovate) and community-led retention through the ACSI Community forum and nine segmented email newsletters.

The technology stack is non-AI-native, centered on a member portal, Learning Portal, e-commerce storefront, Find-a-School search tool, online forums, and the PFO2Go online course platform for international educators. Notable proprietary assets include the Flourishing School Culture Model (a research-based school improvement framework), the Purposeful Design Publications curriculum library (Bible, Language Arts, Science, Math, Literature, Health, Early Education), and the Inspire Accreditation Protocol launched in 2026. Leadership is anchored by President & CEO Dr. Larry Taylor (formerly 20-year Head of Prestonwood Christian Academy), with John Klingstedt as COO, Jerry Nelson as Chief Ministry Officer, and Cindy Dodds as Chief School Improvement Officer.

Direct peers

• Western Association of Schools and Colleges (WASC): One of six U.S. regional accreditors with which ACSI holds partnership agreements for joint accreditation. Offers institutional accreditation at secondary level, overlapping directly with ACSI's accreditation offering for member schools.
• National Council for Private School Accreditation (NCPSA): Umbrella accreditor for private school accrediting organizations, including ACSI. Directly comparable as a peer-recognizing body that provides alternative accreditation pathways to ACSI member schools.
• Council of International Schools (CIS): International membership association that accredits and supports schools worldwide, including faith-based and international Christian schools. Directly comparable to ACSI on international accreditation, university counseling, and global PD events.
• Middle States Association of Colleges and Schools: Regional accreditor covering the mid-Atlantic and parts of the Midwest. ACSI has formal partnerships with MSA and similar regional bodies so that ACSI-accredited schools can also earn regional recognition.
• Cognia: One of the largest U.S. accreditation networks (formed from the merger of AdvancED, NCA, and SACS CASI). Directly comparable to ACSI in providing K-12 institutional accreditation and educator certification, though without ACSI's faith-based specialization.
• Christian Schools International: Parallel Protestant (Reformed/Christian Reformed) school association serving K-12 Christian schools worldwide. Directly comparable to ACSI in faith-based K-12 accreditation, curriculum support, and educator services; the closest mission-aligned peer.

Others

• EdChoice: Leading nonprofit advocating for school choice, vouchers, and tax credit scholarships. Comparable as a policy/advocacy counterpart whose mission complements ACSI's CTF/Public Policy & Legal Affairs work.
• Council for American Private Education (CAPE): Coalition representing private school associations (including ACSI) before the federal government on Title services. Comparable as an advocacy and policy counterpart whose mission overlaps with ACSI's Public Policy & Legal Affairs function.

Emerging players

• BJU Press / BJU Educational Group: Major publisher of Christian K-12 textbooks and distance learning programs. Comparable to ACSI's Purposeful Design Publications as an alternative Christ-centered curriculum supplier competing for the same Christian school purchasing budgets.

Broad incumbents

• National Association of Independent Schools (NAIS): Large U.S. membership association for PreK-12 independent schools, providing advocacy, PD, and resources. Operates in the same K-12 private school space as ACSI but serves a broader (non-faith-specific) constituency.
