Two national surveys of the perceptions of trainers and practitioners regarding assessment and intervention for students with low incidence disabilities (LID) were conducted. The first survey, sent to the directors of 250 school psychology training programs, was designed to determine the extent and type of training in assessment and intervention for students with LID offered in school psychology training programs. The second survey, mailed to 500 randomly selected National Association of School Psychologists' (NASP) members, was developed to assess the extent and type of assessment and intervention for students with LID provided by school practitioners. Responses were received from 121 trainers (50.8% response rate) and 361 practitioners (72.2% response rate). Results indicated, while assessment and intervention for LID remains a small part of the school psychology caseload, school psychologists are using many of the best practice methods. However, recommendations are provided for increased awareness of additional methods, for seeking closer collaboration with special education professionals who specialize in working with this student population, and for more possibilities of subspecialization for future psychologists who will possess expertise in conducting assessment and intervention for LID. © 2005 Wiley Periodicals, Inc.
