In the absence of federal homeschooling guidelines, states regulate homeschooling through a patchwork of provisions. Homeschooling policies vary widely from one state to the next and families' homeschooling experiences will likely be very different depending on where they live. For example, some states have little or no homeschooling regulation--like Alaska, Idaho and Michigan--while others have more robust oversight policies--Washington, New York and Pennsylvania, for example. Although homeschooling occurs largely outside of the public education system, as states provide more online education options and allow homeschooled students to participate, the lines between public education and homeschooling are blurring. Key Takeaways from this report are: (1) Just 13 states plus the District of Columbia require homeschool instructors to have qualifications, usually requiring a high school diploma; (2) Fewer than half of states require homeschooled students to be assessed; and (3) An increasing number of homeschooled students are participating in online education through state online schools, virtual charter schools, or other distance education programs.
