As school choice expands in different states and districts, it appears in several different forms: (1) open enrollment policies among traditional public schools; (2) charter schools available to students regardless of their neighborhood (including online charter schools); or (3) school vouchers that families can use to enroll in other districts or private institutions. Each of these school choice systems can be complex and confusing for low-income families, especially when they are contending with challenges ranging from unstable employment and housing to limited transportation. In the search for solutions, education researchers and policymakers may have overlooked lessons about systems of choice from other policy arenas. This issue focus suggests strategies for consideration from MDRC's extensive experience designing and evaluating interventions to support low-income people's decision making in arenas outside P-12 choice systems.
