About Us

What is ACTI’s Mission?

Asian Cross-Cultural Training Institute (ACTI) exists to serve churches and mission agencies with pre-field preparation of their missionaries. Through a multi-cultural residential program, ACTI seeks to impart the knowledge, skills and character formation needed for cross-cultural workers to be effective in their future ministries.

ACTI was started in 1984 by OMF in response to churches in Asia who were asking for a training program for young people preparing for cross-cultural missionary service. In 1988, it became independent, partnering with mission agencies and churches in Singapore and in Asia to train future cross-cultural workers from around the world.

Who have been trained at ACTI?

ACTI has trained more than 368 cross-cultural missionaries (as of Sep 2017) and workers who are now serving in Asia, Africa and other parts of the world. Our graduates are from S. Korea (29%), Singapore (21%), Hong Kong (11%), India(6%), Taiwan (6%), Malaysia (5%), Japan (4%), Myanmar (4%), Indonesia (3%), the Philippines (2%), other Asian countries (2%) and Western countries (7%). 

We have also began to partner with like-minded organisations to train their nationals or their organisation’s trainees since 2016.

Why ACTI Training is Suitable for you?

At ACTI, prospective cross-cultural Christian workers from across the world meet the real challenges of cross-cultural living, staying in places of training at Chiang Mai and in cosmopolitan Singapore.

Formal interactive lectures give strategic information about various aspects of the world of missions, while hands-on workshops offer skill development. Through the community life, trainees learn first-hand about the intricacies of interpersonal relationships, stress management, raising and keeping a missionary family together, and above all, practicing true discipleship.

 What does ACTI Training look like?

  • formal lectures with interactive discussions and workshops given by 23 active missionaries on 28 topics
  • informal learning through visits to para-ministries, religious practices and mercy ministries
  • interaction with training directors and counsellors to help trainees in their preparation processes
  • a 6-week training program in Chiang Mai/Chiang Rai (4 weeks) and Singapore (2 weeks)
  • a mission week to Chiang Rai for practical training and reality experiences
  • weekly writing of My Reflections to strengthen learning and application for future ministries
  • presenting a Focus Paper & mapping a strategic Masterplan for field ministries



ACTI’s pool of 22 trainers and lecturers come from many different countries as well as from different mission agencies. All the lecturers are practitioners in the mission field with extensive missionary experiences. Each one will be able to utilise their experiences to teach and help the trainees to experience and feel what life will be like on the field.
