Research has not determined whether the SAME children would perform better or worse in a public or private classroom, or in a home-schooling arrangement. Analyses of test scores are available, based on data from states that require testing or from home-schooling associations. Data from both sources may not be representative of home schoolers as a whole, however, because not all families cooperate with state testing requirements and private efforts rely on volunteers. Keeping these caveats in mind, virtually all the available data show that the group of home-schooled children who are tested is above average. The pattern for children for whom data are available resembles that of children in private schools.
People also disagree about whether home schooling helps or hinders a child's social development.
Children engaged in home schooling spend less time with same-aged children and more time with people of different ages. Most spend time with other children through support and networking groups, scouting, churches, and other associations. Many spend time with adults other than their parents through community volunteer work, running their own businesses, tutoring or mentoring arrangements, or other activities. There is no conclusive research suggesting that additional time with same-aged peers is preferable to more time with individuals of varying ages. The practice of home schooling is controversial.
