The estimates of the numbers of home-schooled children vary widely. The U.S. Department of Education estimates there are 250,000 to 350,000 home-schooled children in the country. Home-school advocates put the number much higher—at about a million.
Many public school advocates take a harsh attitude toward home schoolers, perceiving their actions as the ultimate slap in the face for public education and a damaging move for the children. Home schoolers harbor few kind words for public schools, charging shortcomings that range from lack of religious perspective in the curriculum to a herdlike approach to teaching children.
Yet, as public school officials realize they stand little to gain by remaining hostile to the home-school population and as home schoolers realize they can reap benefits from public schools, these hard lines seem to be softening a bit. Public schools and home schoolers have moved closer to tolerance and, in some cases, even cooperation.

A. there isn’t much they can do to change the present situation
B. they want to show their tolerance for different teaching systems
C. home schooling provides a new variety of education for children
D. public schools have so many problems that they cannot offer proper education for all children
