Research has documented higher turnover among professionals working with children with special needs and has suggested a number of reasons for this phenomenon. This study investigated factors affecting job satisfaction of Turkish social professionals working in special education, in terms of work conditions and their work experiences in Turkish special education institutions. Some 245 professionals participated in the study. A questionnaire developed by the authors was administered. The main body of the questionnaire consists of two sections concerning professional background, work status and a Likert-type scale on factors affecting special education professionals' job satisfaction. Results show the factors affecting special education professionals' job satisfaction to include lack of printed material, lack of support, lack of audio-visual material, insufficient assessment, pupil attitudes in the classroom, paperwork overload, lack of professional development opportunities, conflicts with colleagues, secondary duties and insufficient salary. Besides, maintenance of lack of administrative support, paperwork overload, after school hours and insufficient salary affect the job satisfaction of professionals and lead them to leave the job. The relationship between work status and planning to leave the job remained insignificant statistically.
