Approximately 1.3 million public school students in the United States were identified as experiencing some form of homelessness in 2019-20. Due to their unstable living situations, students experiencing homelessness often have additional educational, social, emotional, and material needs compared to their stably housed peers. Housing instability can result in increased absences from school and can lead to students changing schools midyear. Each school move can disrupt students' education and limit opportunities to learn. The multiple challenges associated with homelessness negatively impact student learning outcomes. Reading, mathematics, and science scores for students experiencing homelessness tend to be lower than those of their peers, including those from economically disadvantaged but residentially stable families. While there is a need to focus attention on students experiencing homelessness, school districts may face barriers supporting them. These barriers include unstable funding or funding that is inadequate to meet student needs, and restrictions on the allowable uses of federal funds, which limits district ability to support noneducational expenses, such as for emergency housing. In addition, prior research has found that funding may help districts identify students experiencing homelessness, and without sufficient funding, fewer students are able to be identified as needing support, leading to inadequate services. The purpose of the report is to examine the federal and state funding sources directed to schools to support students experiencing homelessness. [For the research brief, see ED630220.]
