The short answer:

No, it will be a better and more complete education.

The long answer:

No, in most cases it will be much better than the education received by children attending public schools. Although we do not require or endorse standardized testing, research has shown that the majority of children who are home schooled score above grade level on standardized tests. It is not uncommon for a child to proceed through the curriculum faster once he or she has left the traditional environment for home education. Because the responsibility for the child's learning is shifted from the "teacher" to the student, the student tends to "own" his or her knowledge and comes to respect the learning environment homeschool facilitates.
