Congress in 1997 recognized that there were some issues and concerns that had emerged surrounding the Individuals with Disabilities Education Act (IDEA) and sought to address these issues and concerns by mandating a national evaluation on the implementation and progress toward improving outcomes for students with disabilities. The Study of the State and Local Implementation of the Individuals with Disabilities Education Act was designed to address how the amendments of IDEA were being implemented by states, school districts, and schools. This mixed methods study examined the first year of data collected from the six-year Study of the State and Local Implementation of IDEA (SLIIDEA) and analyzing 20 case studies that used interviews of special education personnel and principals, conducted at the local school level. Data from the national survey were examined in light of findings from the case studies. The case studies brought out the varying opinions on implementation success at the local level. Further case studies for each year of the study would be helpful in determining the level of implementation locally and the significant insights of local school personnel on whether these initiatives have worked.
