Experience of practical collaboration of a psychologist-pedagogue with the teachers' collective is reported. The work was organized as psychological-pedagogical consultation of the psychological service type. It has been found out that looking for psychological cause of difficulties in teaching and education as well as for corresponding pedagogical means of correction acquires real significance for teachers only if they themselves directly participated in survey under general control of a psychologist. In such cases examination-of "difficult" classes in particular-enables the members of the consultation group to set forth psychologically sound objectives for the consequent educational work with those classes.
