This is a list of states that have addressed issues of homeschooler participation in public school classes, sports, activities, etc.

Both the number and the proportion of students in the United States who were being homeschooled increased between 1999 and 2003. Approximately 1.1 million students (1,096,000) were being homeschooled in the United States in the spring of 2003, an increase from the estimated 850,000 students who were being homeschooled in the spring of 1999. In addition, the percentage of the entire student population who were being homeschooled increased from 1.7 percent in 1999 to 2.2 percent in 2003.

In this paper, Rob Reich, Department of Political Science, Stanford University, traces the rise of home education, the interests in education held by the government, the parent, and the child, and sets forth his suggestions for balancing these interests. These suggestions lead Reich to conclude that "while the state should not ban homeschooling it must nevertheless regulate its practice with vigilance." This paper caught the attention of many in the homeschooling community and spawned many rebuttals, including:

The Education Resources Information Center (ERIC), sponsored by the Institute of Education Sciences (IES) of the U.S. Department of Education, produces the world’s premier database of journal and non-journal education literature. The ERIC online system provides the public with a centralized ERIC Web site for searching the ERIC bibliographic database of more than 1.1 million citations going back to 1966. More than 107,000 full-text non-journal documents (issued 1993-2004), previously available through fee-based services only, are now available for free.

Homeschooling is a time-honored and widespread practice. It often presents, however, a conflict between the constitutional right of parents to direct the education of their children and the State’s right to impose regulations in the interest of ensuring an educated citizenry. The U.S. Supreme Court has made it clear that any regulation impacting this constitutional right must be “reasonable.” Courts have therefore generally resolved homeschooling cases by examining whether State regulation of homeschooling places an unreasonable burden on the rights of parents. The courts, however, have altogether failed to address another, more fundamental question: whether the State regulation, in fact, advances the State interest. A regulation that fails this criterion cannot be “reasonable.” Using a recent California appellate court case that initially upheld a regulation prohibiting parents from homeschooling their children unless they first obtained a state teaching credential, we show how recent social science research should impact the analysis. Instead of assuming away the issue of whether the regulation advances the State interest, we show that empirical research will allow courts to be able to answer this threshold question.1

One way to examine how student, family, and household characteristics are related to homeschooling is to compare the characteristics of homeschooled students to different populations of students. This study provides a comparison of homeschoolers to non-homeschoolers, both public schooled students and private schooled students, by student, family, and household characteristics.

A summary look at research facts on homeschooling including: general facts and trends, reasons for home educating, academic performance, social, emotional, and psychological development, success in adulthood, and overall success.

This research presents a demographic portrait of the homeschooling community and families in South Carolina through a 22 question survey administered during the 2010-2011 school year to 751 homeschooling families. It is the first study of its kind conducted in the state since 1992, as well as the largest survey sample to date of South Carolina homeschoolers. The data include 1,584 homeschool students, approximately 10% of all South Carolina homeschoolers, with members of the South Carolina Association of Independent Home Schools (SCAIHS) as well as numerous third-option associations throughout the state responding to the survey. Homeschooling families responding to the survey are overwhelmingly intact, two-parent families (97.4%) and are double the size of the typical South Carolina family, averaging 5.04 members with 3.09 children, with the mother as homemaker (69.8%) often acting as principle educator in the home. A majority of responding families (61.3%) report an annual household income in excess of $60,000, substantially higher than the median household income of $44,695 for South Carolina in 2008. The vast majority of respondents were religious (98.6%), white (95%), and Republican (75.4%), all to a greater degree than their national counterparts. Most responding families opposed future enrollment in a public (72.6%) or private (61.6%) school, though many do express an a la carte interest in particular programs offered by local public schools, including athletics, band, choir and orchestra. Responding parents were highly educated, successfully completing high school (98%), a bachelor's degree (39.5%), a master's degree (18.0%), or a doctoral degree (4.6%), with rates of academic achievement comparable to homeschooling parents nationwide. Motivations for homeschooling varied but were typically based upon positive perspectives of the benefits of homeschooling, rather than negative perceptions of public or private schools. This is comparable with homeschooling families nationwide, whose reasons for homeschooling, while diverse, are often framed positively.

This "Learn in Freedom" article provides research supporting the positive socialization homeschooled children receive. Discusses research supporting the conclusion that homeschooled children have higher levels of self-esteem and communication skills, and fewer behavioral problems, than other children.

Homeschooling was growing rapidly in the 1980s in the United States, after starting from a very small base.

Home School Legal Defense Association has compiled research and statistics on homeschooling and other education topics. You'll find information about the number of homeschooled children in the country, the benefits and advantages of homeschooling, and more.

This is an appendix table to the report Homeschoolers: Estimating Numbers and Growth, Spring 1999. It provides an estimate of homeschooled children in 12 states and extrapolates that data out to a national percentage.

This Canadian study has confirmed what has been known for over two decades, much to the chagrin of public school officials: Homeschoolers perform better than public school students in the crucial core academic disciplines of reading and math. The study, published in the Canadian Journal of Behavioural Science, compared the standardized test scores of 37 homeschooled students between the ages of five and 10 to those of 37 public school counterparts, finding that while public school students typically tested at or slightly above their grade level, homeschooled kids performed about a half grade higher in math and 2.2 grades higher in reading.

20,760 student achievement test scores and their family demographics make this one of the largest study of home education. Results demonstrate that home schooled students are doing exceptionally well and provide an informative portrait of America’s modern home education movement. Conducted by Dr. Lawrence M. Rudner, Director of the ERIC Clearinghouse on Assessment and Evaluation.

The Home Education Foundation has several reports detailing statistics on home education in America.

The best research on homeschooling indicates the total number of children who are homeschooled is 1.5 to 2 million, and that number is growing by 10 to 15 percent per year. But not everyone recognizes the academic and social success of homeschoolers and some criticize the movement as being white and elitist. While it's true that the large majority of homeschool children are white, the number of black homeschoolers is growing rapidly. Brian Ray, president of the National Home Education Research Institute, estimates that there are 30,000 to 50,000 black children being homeschooled today. Others estimate that black homeschoolers make up 5 percent of the total homeschool population. Most importantly black homeschool movement is growing at a faster rate than the general homeschool population.

Homeschooling is chosen by families for reasons like apprehensions about school environments, dissatisfaction with academic instruction, and a wish for religious and moral guidance not found in traditional schools. The decentralized homeschooling population complicates researchers' efforts to draw definite conclusions about its effect on outcomes, including academic achievement. Nevertheless, assessments consistently highlight the strong academic performance of homeschooled students.

Significant growth in black families’ participation in home schooling is beginning to show up on the radar screens of researchers. The National Center for Education Statistics computed African-Americans as 9.9 percent of the 850,000 children the federal agency figured were being home-schooled nationally in 1999. Veteran home-schooling researcher Brian Ray figures blacks are currently about 5 percent of the 1.6 million to 2 million home-schooled children but he agrees that black home schooling is growing rapidly.

This brief uses data from the 2003 National Household Education Surveys Program (NHES) to estimate the number of homeschooled students in the United States in 2003 and to discuss the reasons parents decide to homeschool their children. The brief also shows that the number of homeschoolers, and the proportion of the student population they represent, has increased since 1999.

This report, Homeschooling in the United States: 1999, presents an estimate of the number of homeschooled students, characteristics of homeschooled children and their families, parents' reasons for homeschooling, and public school support for homeschoolers. Major findings from the Parent-NHES:1999 indicate that in the spring of 1999, an estimated 850,000 students nationwide were being homeschooled. This amounts to 1.7 percent of U.S. students, ages 5 to 17, with a grade equivalent of kindergarten through grade 12. Four out of five homeschoolers were homeschooled only (82 percent) and one out of five homeschoolers were enrolled in public or private schools part time (18 percent). It also found that a greater percentage of homeschoolers compared to nonhomeschoolers were white, non-Hispanic in 1999—75 percent compared to 65 percent. At the same time, a smaller percentage of homeschoolers were black, non-Hispanic students and a smaller percentage were Hispanic students. Further, it was found that the household income of homeschoolers in 1999 was no different than nonhomeschoolers. However, parents of homeschoolers had higher levels of educational attainment than did parents of nonhomeschoolers.
