Today, there is no doubt that parents can significantly improve educational level by their cooperation in schools. Parents are capable of executing different value-added activities and share their knowledge and experiences with school officials. In this survey, we performed an empirical survey in three provinces of Iran from economically rich to poor. We have chosen 450 committees out of 150 schools. In each province, we have selected 50 schools in different levels from elementary to high school. In our survey, there were 311 people who non-committee, 187 were principals, 738 were members of different committees, 28 were responsible and 25 were from other specialist people. In summary, there were about 1289 participants in this survey. The results of our survey indicate that parents can substantially contribute to schools to increase their capabilities through sharing their knowledge and expertise. However, according to experts, school officials do not strongly believe that the presence of parents can solve any problem and they mostly disagree to share their duties with parents.
