WARSAW, Jan 13 (Reuters) – Poland’s lower house of parliament on Thursday passed a bill by the ruling nationalist Law and Justice (PiS) party which will step up government control of schools and which critics say could curb access to teaching on LGBT and reproductive rights. The bill passed with 227 votes in favour and 214 against, and will now move to the senate. The PiS says changes are needed to protect children, but opponents argue they are part of a wider effort to eliminate liberal values from public life. They warn the law would limit parents’ rights to decide on their children’s education, and leave school administrators with their hands tied. Under the new law, extracurricular activities run by non-governmental organisations in schools will need to be approved by a government-appointed supervisor. The law would also make it easier to fire school principals. Education Minister Przemyslaw Czarnek has said supervisors should have the right to bloc any programming that would be “a threat to the morality of children”, in particular when it comes to sexual education. Agnieszka Dziemianowicz-Bak, a left-wing lawmaker, said on Twitter that instead of tackling depression or extreme poverty among Polish children, Minister Czarnek was working “on the politicization of Polish schools.”
