The two Waldorf methods public schools PLANS brought to court presented numerous witnesses and introduced documents which contradicted this claim. The judge ruled that PLANS could not introduce evidence taken in the context of the private and independent Waldorf schools to argue their case against the public Waldorf-methods schools. The court ruled that private schools are separate entities, and insisted evidence be limited to policies and practices in effect within the litigated public school districts. The two schools furnished statements and documents in this case showing that the teachers in their Waldorf methods schools were held to the same state mandated training and credential requirements as the teachers in other public schools in those districts. In response to a demand to prepare a complete list of all Waldorf-related documents and reading materials related to training or instruction in Waldorf teaching methods, neither school district identified a single text written by Rudolf Steiner. Betty Staley, the Rudolf Steiner College staff member who developed the public teacher training program, testified the college's "1993-1994 Teacher Training Booklists" did not apply to the public teacher training program, and that only one of the texts from the lists, Steiner's "Philosophy of Freedom", was used by the program.
