This paper aims to analyze the role and importance of parents' involvement in educational teams creating an Individual educational plan (IEP) in inclusive settings. The role of good and developed collaboration with parents is well known for a long time in the theory of educational sciences, and particularly in special education and rehabilitation science. Education of students with disabilities and gifted students demand additional engagement, knowledge, and efforts from their teachers, to adjust educational curricula, classroom conditions, methods, and techniques to the abilities and needs of this particular group of students, and to each of them solely and individually. From the moment of involving inclusion in the educational process in Serbia, nine years ago, legislation is adjusted to demand parents' decisions about accepting supporting measures for improving students' development and achievements. The parent became a closer partner to educational professionals but still not an equal member of the educational process and all its steps. The current educational overall law made imperative parents' involvement in the creation of the IEP. This means that parent has to be the equal and honored member of the Team for additional support that is creating IEP, besides other needed members. We reviewed professional and scientific studies that were dealing with parents' involvement in inclusive educational teams for IEP creation. Studies were selected across the known searching services and bases online. Most studies were selected using search words: parents, involvement, individual educational plan, collaboration, and inclusion. Through analyzing the selected studies, we found out some repeated opinions according to several researchers. Firstly, we didn't find any negative opinions or study-based proof regarding parental involvement in decision making and plan IEP planning. All researchers also underline the importance of parents' involvement in these processes. Researchers concluded there is a constant need to improve school collaboration with parents, developing professional capacities of all school staff members, and build up staff communicational skills. The effects of parents' involvement are numerous, mostly are pointed toward increased pupils' achievements and satisfaction of pupils and parents. Parents can help the teamwork with their knowledge about child's habits out of school, its' interests and hobbies, life rhythm of the family, support to learning, ways of application od learned, ways of practical learning, learning styles, unwanted reactions to failure, efficient and proofed ways to encourage a child, etc. On the other side, parents benefits of involvement are: using the right to participate, deepening cooperation, insight into the IEP, impact on the IEP, getting a share of responsibility for educating their children, the ability to contribute to better planning, the possibility to relieve a child of unnecessary obligations, the possibility to point to unprecedented hardships, and a possibility to point out the unrecognized potentials and abilities of the child. It is clear from the researched studies that parents' role in the educational team is very important. The participation of parents in the education teams is required, useful, and needed; the benefit is multiple. All persons involved in cooperation have to review their attitude and attitude towards parental involvement and to empower themselves, especially for teamwork. Schools have to take measures to improve the cooperation and participation of parents, such as teacher training and developing teamwork skills and introducing into practice grouped meetings of IEP teams.
