An intelligence test for blind and low vision children -aged 6 to 15 years- had been constructed and published in 1991. Based on a short vision test, two groups of braille educated children were distinguished: children without usable vision and children with usable vision. No blindfold is used in this test. The results of different types of statistical analyses have been published recently. Within this framework, more detailed quantitative research can be interpreted. The subtests appear to be highly reliable, and achievement in school can be predicted with some accuracy. Factor analysis indicates four interpretable factors in both vision groups. The vision groups -for which separate age-norms were establisheddiffered mainly on tests measuring spatial ability. A Manual in English is available.
