Whereas physical disabled or visual impaired children can sometimes be enrolled in mainstream schools (with support of assisting devices like wheelchairs or Braille), deaf children need special teachers who can teach in sign language. They also need to practice this sign language together. In Nigeria they learn the American Sign Language (ASL), in Guinea-Bissau the Portuguese sign language is taught.
Starting in 1999, CBR Effata gives primary education to children with deafness. The policy changed in 2015. Instead of “Special Education”, “Inclusive Education” is now practiced, which means that children with and without disabilities receive lessons in the same class.
