The following is taken from David’s interview with Mike Turner in 10 Super Coaches.

Would you advise coaches to pursue certification?

Yes, if only because, as the profession settles down, organizations will increasingly only use certified coaches.

If so, at what stage in their practice, and through which accrediting body?

From as early as possible, be clear what the accreditation criteria are and work towards satisfying them. That way, if the accreditation question comes up, you can say that you are working towards accreditation and state which of the requirements you have met or are close to meeting.

Are there any particular school(s) you would recommend?

The London-based School of Coaching, which is part owned by the Work Foundation (a charity that campaigns to improve the quality of work life). Whilst the fact that I am on the faculty might suggest that I would be biased, the reason I work with the School is because of the high quality of its work.
