By Shira Li Bartov(JTA) — A California law to prevent antisemitism in schools will be enforced after a federal judge dismissed a challenge from teachers and students who said it violated free speech. As part of the law, California is establishing an Office of Civil Rights with a new statewide antisemitism prevention coordinator for public schools, who has not yet been appointed. The law mandates teachers to provide “factually accurate” instruction rather than “advocacy, personal opinion, bias, or partisanship.” A group of teachers, students and the American-Arab Anti-Discrimination Committee filed a challenge in November. She also said that teachers and students did not provide sufficient evidence of infringements on free speech, and teachers could not claim speech rights on the job.
