Dean Carlan has a long history of work on charity effectiveness and rigour long pre-dating EA. He has said on twitter that they took a lot of influence and inspiration from EA charity evaluators (esp Givewell). I think the best way of looking at this and much of his other work (for example Innovations for Poverty Action) is that it is EA-aligned organisation but not part of Effective Altruism as a “thing” since it comes from a different community and background and has a narrower focus (“are these charities effective at what they do” v “what overall is the most effective thing we can be doing”)

Again, sorry for not responding sooner, but AlasdairGives is right from what I understand.
