Who we serve…

We serve some of the best Christian schools in the world. These schools are located across the globe from remote areas to the great cities of the world. They employ some of the most creative and adventurous followers of Christ who love students, love learning, and love to help a hurting world through the promise of quality Christian education. These individuals are on our minds continually.

Who we are…

The ACSI international school team is made up of passionate individuals who believe in the transformative impact of international Christian education upon individuals, communities, cities, and countries. It is our continual goal and fervent prayer that our team will be an ongoing source of encouragement, challenge, and improvement stimulus to teachers and leaders in the international schools that we serve.

The international school team is committed...

  • to being responsive to our member’s needs, ideas, and contributions
  • to praying for our schools consistently and look for ways to make them shine
  • to provide ways for international educators to grow in their skills (online PD and live events)
  • to provide encouragement and challenge through regular communication
  • to create community among our member schools in the four continental regions where our schools operate
  • to love the people, teachers, leaders and students in member international schools

We will help to foster...

  • International Christian schools that are flourishing models of quality education, an encouragement to sister-international schools and nearby national Christian schools, a source of hope and love in their surrounding neighborhoods, cities, regions, and nations, and...
  • the graduates of member international schools who will be Christ-following, difference-makers in their spheres of influence
