The Department for Education and Skills uses the Central Office of Information (COI) for “above the line” advertising campaigns; it does not keep separate information centrally on any subcontracted consultancy services that COI may employ relating to any advertising campaigns. The Department contracts with agencies for "below the line" publicity, including design agencies and PR agencies—but these are for services such as design and PR services, not consultancy.
The Department for Education and Skills does not have any agencies.
