The revamped PMD has been formed from the combination of the Preferred Developer Consultant (PDC) and Marketing API (MAP) programmes. It offers certifications for high-quality apps, page management, ads, and insights tools and services.
The 14 UK-based companies have joined 233 global firms on the list.
The UK companies are: TBG Digital, which was one of the original Facebook API partners; Jollywise Media; Kerve Creative Ltd; glue Isobar; Sports New Media; AKQA; OneIota; Reevoo; Comufy; Apsmart Ltd; Independents United; EngageSciences; PageHub and Dare
Companies admitted to the programme must be adept at understanding the Facebook platform policy and development tools, as well as having a long track record of providing Facebook-centric services to brands.
Last week, Carolyn Everson, global marketing partner at Facebook, told Campaign that media and creative agencies have a "critical" role to play in the company's future plans.
