School Reviews
5 6/1/2009
River Valley Charter is an exceptional, award winning school, offering the highest academic scores and achievements, for those who are interested in combining a public and homeschool environment. The children who attend are respectful and well-behaved. The teachers truly care for each student and demonstrate their concern by offering individualized tutoring and communicating well with the parents. Their student to teacher ratio is only 18:1 which is invaluable to the student. If there is a downside, I haven't found it. This school is not recommended for children who do not want an education or for parents who are unable to homeschool their child on the independent study days. It is the perfect blend of technology, acdemics, and support, served up in an atmosphere of peaceful safety where children smile.

As a result, House democrats have taken up the issue in a new bill that would ban all forms of corporal punishment nationwide.
