Attorney General of Kansas Kris Kobach released a statement Thursday criticizing several public schools in Kansas for allegedly allowing teachers to conceal from parents their child’s transgender status, despite a policy letter sent to school’s in December.

After the December letter, Kobach alleged that four school districts did not change their policies: Kansas City, Olathe, Shawnee Mission and Topeka. According to Kobach the school’s policies, which currently allow teachers to conceal a students transgender status from parents if requested by the student, violate the parents “fundamental constitutional right to direct both the education and upbringing of their children.” Kobach also claimed that transitioning can cause “major long-term medical and psychological ramifications.”

This is the latest action in the state’s controversial battle to restrict transgender expression in schools and beyond. Last year a bill was introduced that would prevent school employees from addressing students using pronouns “that differ from the pronoun that aligns with the student’s biological sex unless the school district has received written permission from the student’s parent or guardian.” In addition, last year the Kansas Legislature successfully overrided the veto of Governor Laura Kelly to a law directing birth certificates to be based on biological sex at birth.
