With the number of homeless unaccompanied youth continuing to rise in the United States, it is imperative that schools learn and understand federal guidelines and best practices to be able to best support these young people. Professional development can be a critical step in supporting these students. This study explored educators' understanding before and after participating in a professional development workshop about homeless unaccompanied youth. The inquiry questions investigated to what extent the school personnel showed an increased understanding of youth homelessness after a 30-minute online training video and if the same school personnel could apply what they had learned in case study examples. To accomplish this a pretest and posttest and a 30 minute training video were added to a spring K-12 Principal Certification course at a Mid-Atlantic University. The statistical analysis of the pre- and posttest scores showed a significant increase in knowledge from the pretest to the posttest. Some improvements to the professional development could be made to help see an increase in scores as relates to the case study questions where participants were asked to apply the new knowledge. Through professional development, districts can increase educator awareness and knowledge of homeless unaccompanied youth and aid in staff's learning of basic policy mandates and best practices.
