After mid-2000s programs of modernization of schools (basic and secondary) and the construction of new elementary schools called "educational centres" (mostly to reduce the number of overloaded elementary schools, to widespread the 9 AM to 5h30 PM schedule system, because in most overloaded schools there are classes with 8 AM-1 PM schedule and other with 1 PM-6 PM) are being held.
