The competency to plan and carry out one’s own professional development was included among ten key competencies of the teacher competence profile, specified within the project Evaluation of Teacher Competencies, the goal of which was to develop evaluation tools to each of the ten competencies. Applicability of the created sets of the tools (observation sheets for the evaluators Assessment Sheets, observation sheets for the evaluated Self-Assessment Sheets and Record Sheets to support subsequent Post-Observation Interviews) to all specified key competencies was verified during their pilot application at schools all over Slovakia. In the paper the authors present findings relevant to the continuing professional development of teachers, which resulted from the piloting of the assessment tools to the competency to plan and carry out one’s own professional development. The findings are structured into three main areas–teachers continuing professional development from the point of view of the school management, from the point of view of the heads of the subject committees, and from the point of view of the teachers themselves.
