Bangladesh Children’s Sponsorship Services (BCSS) originated from Kellogg-Mookerjee Memorial Seminary (KMMS) School. Under the leadership of N.C. Dewri, BCSS was initially connected with the Christian Children’s Fund (CCF) in 1971 to support student sponsorships. Byron B. Bol played a key role in collecting student data despite the challenges of the civil war.

BCSS expanded beyond KMMS, officially becoming a department in 1975 under Isaac P. Bairagee. It underwent name changes, first to Bangladesh Christian Sponsorship Services (BCSS) and later to its current name in the late 1990s to ensure inclusivity. Several NGOs, including World Vision and Asian Aid Organization (Australia), collaborated with BCSS to support children, particularly in boarding schools and orphanages.

The organization grew significantly, sponsoring over 5,000 children by 2005. However, funding withdrawals, especially by Waid Love (USA), led to a reduction in operations. Support from Garwin McNeilus (Maranatha Ministry) and Dr. Milan Moskala (ADRA Czech Republic) helped stabilize sponsorships, though another financial setback in 2010 affected major boarding schools. BCSS regained strength through continued support from Asian Aid Organization Australia and other donors, shifting focus from individual sponsorship to Child-Focused Community and School Development programs.

By 2013, BCSS sponsored 3,065 children, though numbers fluctuated due to global financial challenges. Various international partners, including ADRA, REACH Canada, Danish Children’s Fund, and Child Impact International, played key roles in sustaining its mission. Despite hardships, BCSS continued to support underprivileged children, ensuring the survival and growth of Adventist schools in Bangladesh.
