In ongoing challenges against the Waldorf methods public schools in other districts, PLANS pointedly referenced their pending lawsuit, warning that other districts too would face expensive legal challenges if they allowed Waldorf based methods in any of their schools. PLANS' challenges against Waldorf methods charter schools in the Chico Unified and Ross Valley school districts resulted in the denial of pending charter school proposals there. However, the proponents of those charters soon reapplied in alternative districts nearby and both charters were accepted: the Blue Oaks Charter School, opened September 2001 under Chico's Butte County Office of Education, and the Waldorf-Inspired School of Lagunitas, opened September 2004 in the Lagunitas School District. Sacramento Unified, Twin Ridges Elementary, and Yuba County districts also continue to operate their Waldorf methods programs. Today, there are 19 public schools in California that have adopted the Waldorf methods.
