A training phase may be introduced to train the client to make use of the full intervention. Sometimes notations of training phases are added; sometimes the training is included in the intervention itself so no special notation is used. These notations could be: A-B1 (training)-B2 (intervention); A-T (training)-B; or A-B (when the intervention includes a training phase). (See the discussion of Training Phases below.)
