IDEAS first Constitution was proposed by a Steering Committee of nine members (six from developing countries and three from developed countries). It was approved and adopted on 8 September 2002, in Beijing (China), when a Constituent Assembly launched IDEAS, elected a widely representative Board composed of ten members, and approved a three-year work plan and budget.

Over time amendments became necessary, to follow the historical functioning of the Association, while preserving its principles. In September 2016, members approved a new Constitution that better reflects the nature of a professional association with a charitable purpose and addresses the needs of the growing Association.

The last revision of the Constitution was approved by IDEAS members in December 2018, jointly with the new Election By-Laws.
