No-one. But there is a group of dedicated colleagues, trainers in motivational interviewing, who have formed an organisation called MINT (Motivational Interviewing Network of Trainers). William R Miller and I helped to form this network, and support it actively. But we don't run it, they do. And our vision was not to construct a formal licensing system or anything like that, but a forum that promotes good practice. MINT does this in a variety of ways (see www.motivationalinterview.org). What is striking about MINT is the voluntary nature of these efforts. If you take a look at the MINT Bulletin on this site, you will glimpse the diversity and commitment to good practice that is expressed by the contributors, all members of MINT. MINT organises training for trainers (see separate question below).

There's undoubtedly a limitation to the approach Miller and I and other colleagues have taken - our decision not to try to control the practice of others means that poor practice is more likely to occur, and certainly it means that the quality of training in motivational interviewing is likely to be variable.

There are now movements afoot to improve things, like with the certification of practitioners (see separate FAQ).  certification of trainers might follow, but I am not sure about this.
