The purpose of this qualitative study was to identify and describe the implementation practices being used by school districts to notify and enroll parents into Supplemental Educational Services under No Child Left Behind. Parents participating in choice programs in the school districts of Savannah, Atlanta and Detroit participated in a survey study that identified specific practices used by districts to alert them of their eligibility to enroll into choice programs mandated to schools deemed as "Academically Low Performing" for two consecutive years or more. The specific implementation practices identified in this study were collected using a combination of research data collection methods and techniques. These methods and techniques included surveys and interviews with administrators and parents that were utilized to acquire data that described the methods of notification and enrollment. The findings in this study demonstrated that the school districts are making parents aware of their parental choice options through a series of coordinated efforts. The practice of implementing No Child Left Behind parent choice programs, from the school and through direct mailings and site based enrollment coupled with online enrollment, were practices most frequently used and preferred by parents based on the findings. The impact of the findings in this study is central to guiding the implementation efforts made by districts and to the body of scholarly work surrounding No Child Left Behind.
