Each school is part of the community and at the same time, a provider of education services. This makes school a Learning Community for both teachers and students. While in the case of students this is a mission accomplished, in that of teachers' things seem to be a bit more difficult. The latter ones should see themselves as members of a Professional Learning Community (PLC), where each teacher should cooperate with the other to achieve common goals, engage in common research activities for the progress of their school, take part in evaluating school results and propose plans to improve them etc. This research aimed to identify teachers' perception of the role of school as a Professional Learning Community, to identify how school boards support and encourage this idea through participative management and to identify lines of joint research in which teachers are involved. The instrument used was a questionnaire having 30 close-ended items, administered to pre-university teachers from Bihor county, Romania. The implementation period was January to June 2016. The results show that there is collaboration between the same subject area teachers, who form committees to discuss, analyse and propose solutions. The research has also showed that more effort is required to improve collaboration between more experienced teachers and those who are at the beginning of their career, to improve collaboration between different subject area teachers by getting them to engage in joint projects, but above all, there is a need for a greater involvement of teachers, of school boards in managing schools so that participative management is achieved.
