ATA was established in 2005 to act as a voluntary licence to practise for the automotive sector and takes the form of practical and knowledge based assessments, designed to test technicians' competence.
IMI has subsequently awarded over 53,000 accreditations across 18 routes.
"Our main focus is to ensure IMI Accreditation provides a robust solution for proving the current competence of individuals working in the sector," states IMI CEO Steve Nash.
"We believe this can be better achieved through stronger association with the wider activities of IMI," he continues.
"The rebranding of both ATA and AMA will also allow us to develop a clear brand strategy, which provides the public with a straightforward way of finding automotive professionals who invest in their skills."
