San Francisco Unified has one huge advantage over private schools - language immersion. Most private schools are smaller, so they can only offer one foreign language to their students. Language immersion programs may be the savior for SF public schools. Currently, SFUSD offers Spanish, Korean, Japanese, Cantonese and Mandarin immersion programs. They are all very popular and have been successful. So why doesn't every school have an immersion program? Most other countries have foreign language curriculum starting in elementary school - we should as well. If we want our children to be able to compete in a 21st Century economy then they need to learn another foreign language to be able to participate in the world economy.
