This is our training of trainers (TOT) course. This is a modular training for different categories of Gospel workers, especially those in leadership positions of church denominations and mission agencies. Christian Mission is dynamic, therefore Christian workers must keep abreast of current trends in the global mission’s landscape. In today’s ever-changing ministry and cultural contexts, BAIS affords mission practitioners an opportunity to consistently acquire skills and develop attitudes needed to competently engage their work. The courses offered in the BAIS prepare participants for effective kingdom service. The BAIS runs twice a year: May/ June and October/ November, for three years. The BAIS affords participants opportunity to work and learn simultaneously.
