It should not be concluded however that every mobility specialist is equipped to work with children, to work with vision impairments, or to work with non-categorical populations. There is controversy about the role of the typical orientation and mobility specialist. In many cases, school based mobility specialists do not feel competent, nor do they feel that they have the time to serve children other than blind or severely visually impaired students. Teaching children involves an understanding of child development. The degree of knowledge and experience that mobility specialists gained during professional training varies with universities, so some may have received more background in child development than others.
Vision problems come in a bewildering collection of degrees of severity and varieties of impairment.
Some mobility specialists have a better background to interpret and prescribe for these vision problems. In my own practice, I serve children on a priority basis. Primarily, I serve totally blind, cognitively normal children first. These kids need all my expertise and a great deal of my time. If I have additional time in a week after all the totally blind children are served, I also teach multiply impaired blind children and students with severe vision problems.
