The law establishes free access to the last two levels of pre-school. A constitutional reform in 2013 called for the law to extend free access to four levels, and make the last one mandatory and a prerequisite to enter primary school.
The coverage for pre-school in 2009 was 37.42% (for children aged 0 to 5) and 44.96% (for persons of any age).
