Parent involvement in the development of an individualized education program (IEP) is a foundational tenet of the Individuals With Disabilities Education Act (IDEA). Unfortunately, mothers, the parent most likely to attend the IEP meeting, often report negative perceptions and even feelings of disillusion with the IEP process. Including mothers as equal members of the IEP team is crucial to student success, especially for students with intellectual and developmental disabilities (IDD). To determine the extent of mothers' satisfaction, trust, and perception of the power of the IEP process, we surveyed 929 mothers of students with disabilities. Survey results indicate mothers are neither overly satisfied nor dissatisfied with the process, but almost always perceive an imbalance of power between IEP team members. A high percentage of mothers reported experiences with bullying, coercion, and shame. The findings suggest that more efforts are needed to empower mothers during the IEP process and improve parent-school partnerships.
