Although many may be surprised at the growth of homeschooling during the past few decades, the real surprise is probably how that growth happened and that it continues. Home school advocates and practitioners have succeeded despite a lack of funding, recruiting efforts, publicity, and grant money from philanthropic billionaires. They have faced opposition from the National Education Association (NEA), obstacles imposed by individual school districts and various state restrictions, regulations, and requirements. There is also little if any professional development for parent-instructors and virtually no future career path (or pensions) for those parents. Systemically, there is a lack of institutional knowledge with which to keep the homeschooling movement going forward. This paper attempts to elucidate some of these issues by reviewing a brief history of homeschooling, the challenges associated with defining and counting homeschoolers, the predominant reasons for homeschooling, and the critical role parental choice plays in the decision to homeschool. By becoming more knowledgeable about the practices and benefits of homeschooling, traditional educators can begin to offer parents information, support, and encouragement, treating them as educational colleagues who care deeply about children's learning.
