In the U.S., with an increasing number of parents taking their children out of class, school officials are looking for ways to restore parents' confidence in the public education system. Some American high schools have opened their doors to homeschoolers on a part-time basis, allowing these children to attend classes once or twice a week, or to take part in activities such as playing football or doing ballet. This enables homeschooled children to enjoy the extra benefits of peer interaction and involvement in sports or clubs.
