In January 2006, Pearson VUE announced the acquisition of Promissor; bringing together two of the world’s leading organizations in the professional testing industry.

Together, Pearson VUE and Promissor form a business focused on providing full-service testing solutions with unmatched service to enhance the performance, reliability and security of computer-based testing programs throughout the world. Clients and test takers will benefit from an advanced test center network, greater capacity, and the most innovative testing system in the industry.

Corporate Vision Strategists created the Promissor brand and the vision of "knowledge beyond doubt"™. The name Promissor captures the essence of this leader in global assessment and knowledge management: Promissor comes from the Latin for guarantor, suretor. Promissor’s symbol portrays both the “P” for Promissor and Phi, the Greek letter that represents the universal metric found in proportional relationships throughout the universe - a numerical exactitude.
