Private school choice programs are publicly-funded programs that provide families with funding to attend a private school of their choice. Since 2021, 15 states have enacted or expanded choice legislation, even making homeschoolers eligible to participate. However, homeschoolers are often reluctant to participate due to proposed regulations. We survey a national sample of hybrid school leaders, a sector that shares similarities with homeschoolers in modality, and randomly assign hypothetical regulations to them. We find that 65% are willing to encourage participation in the absence of regulations, but regulations reduce leaders' willingness to encourage participation by about 31 points.
