The use of video assistant referees (VARs) in football was included in the Laws of the Game in the 2018/2019 edition. Through the FIFA Quality Programme for VAR Technology, FIFA assesses the technological aspects of VAR systems.

To support competition organisers with the implementation of the technology, FIFA and The IFAB introduced the Implementation Assistance and Approval Programme (IAAP). This allows the same standards to be applied when using VARs in a new competition, offering assistance in tackling the challenges related to the organisation and management of VAR implementation and overseeing training programmes for personnel in charge of VAR technology.
