In the 2020-2021 school year, more than 25 million children and youth -- roughly half of all elementary and secondary students in the United States -- attended schools in school districts that lacked dedicated funding to identify and support students experiencing homelessness. This significant funding gap increases the likelihood that many children and youth experiencing homelessness will not be identified, and even in cases where they are identified, that they will not receive the educational protections and services that can stabilize their education and their lives. Ensuring access to these supports is an important part of creating a school system that meets the needs of all of the nation's children and youth. This brief analyzes publicly-available preK-12 federal education data for the 2020-2021 school year to examine patterns that are correlated with under-identifying and inadequately supporting children and youth experiencing homelessness.
