children with physical disabilities, depending on the nature, extent of disability and availability of local specialised institutions, attend either such institutions or special classes within regular schools. as of 2007, there were 80 schools for the blind and the children with poor eyesight; their school term is extended to 12 years and classes are limited to 9-12 pupils per teacher. education for the deaf is provided by 99 specialized kindergartens and 207 secondary boarding schools; children who were born deaf are admitted to specialized kindergartens as early as possible, ideally from 18 months of age; they are schooled separately from children who lost hearing "after" acquiring basic speech skills. vocational schools for the working deaf people who have not completed secondary education exist in five cities only. another wide network of specializes institutions takes care of children with mobility disorders. 60-70% of all children with cerebral palsy are schooled through this channel. children are admitted to specialises kindergartens at three or four years of age and are streamed into narrow specialty groups; the specialisation continues throughout their school term that may extend to thirteen years. the system, however, is not ready to accept children who also display evident developmental disability; they have no other option than home schooling. all graduates of physical disability schools are entitled to the same level of secondary education certificates as normal graduates.
