The traditions and author’s understanding of training the future psychotherapists in medical and psychological institutions of higher education and retraining of specialists in the field of psychotherapy, as well as the role and importance of psycholinguistic knowledge, discursive skills, abilities and competencies in psychotherapeutic education are described. The results of monitoring the content of training the psychotherapists in medical and psychological institutions of higher education in the specialties: “clinical psychology”, “psychotherapy” are shown, the imperfection characteristic for the current psychotherapeutic education are described, and it is emphasized on existing of the problem of significant terminological disorder not only among the names of specialities acording to which the psychotherapists are trained, but also in the educational and professional qualifications received by future specialists.
