Homeschooling was seen as the “norm” up until about 1970. In the late 1970s, the number of children homeschooled increased again, and the number of homeschooled children in 2010 was about 2 million. Research has been done on the test scores and behavior of those children being taught by their own parents. After mass amounts of research, homeschooling has been found to be more beneficial than harmful to those being educated at home. Those in opposition to homeschooling argue that it messes with the academic, social, emotional, and psychological development of the students.
