Osborn Elementary School

History of TWI

Two-way immersion education has been in existence in the United States for nearly 40 years, but its growth in popularity is a more recent phenomenon. The number of schools participating in TWI programs has been on the rise for the past 15 years with over 300 schools nationwide and almost 200 in California. The majority of these programs are Spanish/English programs in public elementary schools. Moreover, this immersion program is modeled off of the Canadian French-English Immersion Model which has an even longer history.
