Many states now allow public online high school programs. Some of these online schools are created by district or state organizations. Others are run by local charter schools. A recent NPR article reports:

"Online education for high school students is gaining popularity, but it may not realize one of the original promises of distance education: saving money. The start-up costs can be substantial, and it's tough to compare the costs of a virtual school with those of a brick-and-mortar one.

Online educators say the real payoff is that these virtual schools can help liven up traditional schools."
