In this same year, more than half (57%) of special basic education schools were private-subsidised while 43% were public schools. There were only three private non-subsidised schools offering this modality of education (Ministry of Education, 2016). Close to two-thirds (65.8%) of students in special education basic schools attend private-subsidised schools, 34% attend municipal schools, and only 0.1% attend private non-subsidised schools (Ministry of Education, 2016). As shown in Figure 3.4, enrolment in special basic education increased significantly during the last decade, particularly in the private-subsidised sector, where it went from 15 790 students in 2004 to 26 249 students in 2015, a 66% increase (compared to a 11% increase in public schools) (Ministry of Education, 2016). Only 2.2% correspond to students with visual or hearing impairments. The proportion of students with autism is twice as large in private-subsidised schools (5.0%) as in municipal schools (2.6%).
