was held such arrangements constitute unlawful discrimination on the ground of sex. In Equal Opportunities Commission v. Director of Education, the Secondary School Place Allocation System was challenged as being discriminatory towards girls. To help boys overcome the late bloom, a scaling system was introduced whereby boys and girls scores were scaled separately. The result was that the final score of boys were boosted and those of girls reduced.
