The method of a questionnaire survey was chosen for the research, a questionnaire of semi-closed questions was created. The study involved 353 general education teachers. The results of the teacher survey showed that parents are not sufficiently involved in the process of cooperation. The most common forms of cooperation between teachers are individual consultations.
