A quasi-experimental study showed that the reform in question reduced the number of hours adolescents spent without adult supervision, which affected risk behaviors related to teenage pregnancy and criminal activities [1].
The results presented indicate that a 20% increase in the accessibility of full-day educational establishments reduces teenage pregnancy by 3%, and that this increase can explain 1/8 of the reduction in teenage childbearing since the implementation of the reform.
Likewise, for every 20-percentage-point increase in educational reform coverage, the average crime rate at the municipal level fell by 17.5%, or 21.7 crimes per 100,000 inhabitants. The greatest impact was on property crime, which fell to 17.7 crimes per 100,000 inhabitants, a 22% decrease.
Chile’s school reform reduced violent crime by 12%, or 2 crimes per 100,000 population for every 20-percentage-point increase in the school day. The results hold when controlling for the characteristics of the municipalities, with reductions of 19%, 24%, and 11% for total crime, property crime, and violent crime, respectively.
