About Us

ACTI’s Beginnings

ACTI was originally started by OMF in 1984 in response to churches in Asia faced with a new wave of Asian missionaries needing cross-cultural training as well as from Western countries who were sending Their missionaries new to Asia. With this need, a rented bungalow at Adam Road became the first venue to host the trainees for a period of one year.

After four years of existence, ACTI became independent in 1988, a partnership realised with different mission agencies and churches in Singapore networked together. Bringing in experienced missionaries working in Asia as trainers, it became a place in Asia for those needing cross-cultural training from different parts of the world.

ACTI’s Trainees

ACTI has trained 401 cross-cultural missionaries (as of Apr 2019) and workers who are now serving in Asia, Africa and other parts of the world. Our graduates are from Singapore, S. Korea, Hong Kong, India, Taiwan, Malaysia, Japan, USA, Australia, Netherlands, Indonesia, Myanmar, the Philippines, and other Asian countries.

We have also began to partner with like-minded organisations to train their nationals or their organisation’s trainees since 2016. This has resulted in new training areas, in their own context in other countries.

Suitability of ACTI Training

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, practising true discipleship.
