This descriptive study examined the readability levels of Individualized Family Service Plans (IFSPs). The readability of 85 de-identified IFSP documents developed by seven agencies that serve families and children enrolled in a county early intervention program was analyzed using Flesch Kincaid grade levels and Flesch reading ease scores. The average Flesch Kincaid grade level of the entire IFSP documents was 8.0, indicating that the text was written at the 8th grade reading level. The Flesch reading ease mean score for all of the IFSP documents was 58.6, indicating that the text was written at a moderate level of ease to read. The highest Flesch Kincaid grade level scores and lowest reading ease scores were found in sections that require descriptive documentation of IFSP activities and ideas, justification for services provided outside of the natural environment, the way in which outcomes would be met, and a description of the activities provided in the natural environment. The lowest Flesch Kincaid grade level and the highest reading ease level were found in the section involving gross motor development. There were no agencies that prepared IFSP documents at or below the recommended 5th grade reading level. The findings from this study indicated that on average the entire IFSP documents and most sections of the documents were written above a 5th grade reading level. Overall there were no agencies that wrote the IFSP documents at or below the recommended 5th grade reading level. Analysis of readability levels when preparing IFSP documents is recommended to optimize accessibility and usability.
