The writing of legally compliant Individualized Education Programs (IEP) has been a difficult task for many educators. Poor quality writing of IEPs has caused a myriad of issues. Parents have brought lawsuits upon school districts and inaccurately written IEPs have been interpreted erroneously or presented an incorrect picture of the student. Teachers and related service providers need training and practice related to the quality and content of IEPs. This report focuses on improving the current practice surrounding professional development of IEP writing and updating educators on the content of IEPs. There were many reasons for poor IEP writing including a lack of knowledge, a lack of time, and not having received sufficient training regarding IEP preparation. Professional development consisting of one workshop was not sufficient in producing effectively written IEPs. A professional development process was put into place to increase the compliance of IEPs for five participant preschool teachers. Continuous Professional Development (CPD) including a planned, ongoing schedule of in-service learning is suggested to increase and compliment professional knowledge. Face-to-face learning, web-based learning, and coaching were used to create a comprehensive CPD plan to increase the legal compliance of IEPs written. Intervention was targeted based on patterns of errors found in drafted IEPs from the previous school year. Error rates on drafted IEPs were collected and the mean of errors prior to CPD was determined. Data on error rates were collected throughout the CPD sessions to determine improvement rates. Data suggested that compliance of IEPs increased during the data collection period of 2021 to 2022 school year. The compliant IEPs increased their appropriateness due to the evidence provided within the documents and allowed for greater student success. Time could be saved as less time was needed for completing IEP reviews and updating draft IEPs. The conclusion is that the implementation of CPD sessions resulted in increased compliance of IEPs and should be used for training special education teachers on IEP writing.
