This report was released by the National Center for Special Education Research (NCSER) on January 23, 2008. Orientation refers to one's ability to determine his/her location and relationship with other objects in the environment. Mobility refers to one's ability to move about in the environment. Orientation and mobility training may be provided to students with visual impairments as part of their individual programs of special education and related services. This report presents information on the percentages of students with visual impairments who receive orientation and mobility services, including percentages for different segments of the population (blind vs. partially sighted, regular vs. special school placement, and demographic groups). It also discusses the levels of orientation and mobility skills in this population, and factors associated with their skill levels. Data are from The National Longitudinal Transition Study-2 (NLTS2), funded by the National Center for Special Education Research at the Institute of Education Sciences, U. S. Department of Education. NLTS2 was initiated in 2001 and has a nationally-representative sample of more than 11,000 students with disabilities. (Contains 6 figures and 7 footnotes.)
