Because they are admitted to the school at varying ages, but all having to start at Class1, the classes contain a very varied age range and also of course very mixed ability. Many children have been severely handicapped by having been kept at home in childhood, allowed to do nothing and were never stimulated mentally or physically. There are about 5 girls in their late teens who lost their sight at primary school age and, though belonging to educated families, sat at home for several years doing nothing, having lost all hope because they didn't realise that they could continue their education in braille.
Most children come from economically and educationally poor backgrounds.
In fact most families can't comprehend how they could be educated. None of the families pays any fees. The school is staffed by a specially trained headmistress, five resident blind teachers, and eight sighted ones who come in daily. Most of the teachers are Christians. They have all qualified as specialist teachers of the blind.
