With regard to children's participation rights, it was concluded that teachers mainly emphasized students' rights to freely express their views and participate in decisionmaking processes related to them. It was concluded that teachers' activities in preschool period concerning children's rights and their participation rights are in accordance with the nature of the child's learning process. It was determined that the most important problem that teachers face while teaching children their rights and ensuring their participation rights is because of the traditional attitude of families. In addition, it was concluded that teachers face problems because of children's cognitive/developmental characteristics, having difficulty in expressing themselves or being shy. Seminars, conferences, trainings, etc. for raising awareness of families and teachers on children's rights and children participation rights may be proposed.
