This report is the first in a series that unpacks the barriers to access that families face, the variety of solutions that navigation organizations have developed, and the challenges that limit the reach and impact of those solutions. This series offers recommendations for how to help navigators address these challenges and support more families and students. In many ways, families across the country have never had more access to learning options. Participating in the learning ecosystem requires families to dedicate more time and energy to making decisions on behalf of their children. For many families, those decisions can be daunting. For some families, the entwinement of those decisions with other needs and constraints creates barriers that are insurmountable without support. The disconnect between family demand and participation is indicative of challenges that complicate families' access to learning options, including financial constraints, logistical barriers, and limited access to the information they need to make decisions. Building on the approaches of early navigators in school choice, other organizations have emerged to help families navigate different learning options. This report discusses how navigation organizations help enable families' access to learning options.
