The island adopted free, universal secondary education and a social security system. There was also a slum clearance programme involving States-funded homes (either for social housing or sale) and States-funded mortgages. The bill for the social security system was passed in May 1950. A paid police force to cover the whole island was established to work alongside the honorary police. Divorce was legalised in 1949. In 1952, a state secondary school for boys was opened at Hautlieu and a girls' secondary was opened at Rouge Bouillon. Ten years later these would combine to form a single co-ed grammar school at Hautlieu, and two other schools: one for boys (d'Hautrée) and another for girls (at the Rouge Bouillon site) were opened. Later the two St Helier schools were combined into one comprehensive school and two other comprehensives were opened at Les Quennevais and Le Rocquier. Highlands College was purchased by the States in 1973 to provide further education.:280
