In April 2015, the Government of Thailand announced its decision to introduce an unconditional Child Support Grant for children up to one year of age living in poor and nearpoor households across the nation to improve the status of young children in the country, particularly in relation with their nutritional status. In May 2015, approving the CSG for implementation, Thailand’s Deputy Prime Minister Yongyuth Yuthavong made clear the importance of credible evidence in both initiating the programme and guiding its future development. The programme was announced, designed and implemented at an unprecedented pace – rolling out within six months of the approval and implementation decisions. In March 2016 (six months after the first disbursement), the government expanded age-eligibility to cover the initially eligible children for an additional two years (up to the age of three, from the initial age limit of one year), with an increase in the benefit value to THB 600 per month effective October 2016 (one year after programme commencement).
