The accreditation, which will give an approved scheme for field marketing practitioners and clients, expands on points made in the DMA Code of Conduct by identifying 19 key areas for achieving higher standards, including understanding a client brief, and improving quotation and costings.
The Best Practice Accreditation, which will be paid-for but not for-profit, will be passed by the DMA Compliance team's test process, and involves a written application, a day-long onsite audit with a DMA representative, and a 57 point compliancy procedure.
The DMA said a crucial part of its accreditation process involved awards only being given "where 100% compliance is demonstrated".
Steve Radford, vice-chairman of the DMA Field Marketing Council, said: "Of the clients surveyed in advance, all said that the scheme will make future purchasing processes and decisions easier.
"By selecting an accredited company they can be sure that they are working with one of the very best field marketing providers. The scheme will of course continually evolve as the industry and demands placed upon it change, and we will be actively seeking further engagement with clients and other relevant parties to help in this process."
