This article presents arguments for applying the transactional analysis (TA) in the coaching. Theoretical notions, techniques and workings models of TA can arrange a practice of coaching. Coaching simply needs many theories as sources of its inspiration. TA refers to a current of positive psychology. It discusses a norm and a supporting the development and it does not concentrate on pathology. TA is the conception, which the language is simply, blunt and humorous.

The article presents the original PERMA model of coaching. Theoretical bases of the model are outlined, i.e. the Authentic Happiness Theory, along with three models devised by Martin Seligman: the pleasant life, the good (committed) life and the meaningful life, as well as his well-being theory formulated later. Authors also refer to the concept of character strengths and virtues introduced by Christopher Peterson and Martin Seligman, and propose the application of the classification of character strengths and virtues VIA (Values in Action) in the coaching process based on the PERMA model.
