DUSHANBE (Reuters) - Tajik-istan has banned school and university teachers under the age of 50 from growing beards and limited the beard length for older education staff. According to the rules, published at the weekend and effective from Oct 1, teachers aged over 50, can wear a tidy beard no more than 3 centimetres long. But, in a balancing nod to conservatism, the new rules also prohibit teachers from wearing Western-style clothes such as jeans, mini skirts and T-shirts. All those novelties are introduced as part of an ongoing school and higher education reform and are in line with the mentality and the customs of our people, education ministry spokesman told reporters on Monday. Tajik President Imomali Rakhmon has earlier banned mobile phones from schools and universities and said students should not arrive for lessons in their own cars.
