The primary purpose of this paper is to review major factors: (a) external (e.g., societal, economic, research findings related to teacher retention and and institutional), (b) employment (e.g., profesattrition in special education. Major findings sional qualifications, work conditions and rewards, from general education retention studies are also commitment, and employability), and (c) perreviewed to provide a context for understanding sonal (e.g., demographics, family, and cognitive/ special educators' career decisions. Research findaffective). Conceptual and methodological conings are organized around a conceptual model of siderations related to attrition/retention research teachers' career decisions that includes three are also considered.An examination of teacher retention and attrition is timely in this era of special education teacher shortages. Boe (1990) suggests that teacher retention is the most promising approach to minimizing teacher shortages in special education since attrition is the major factor causing the shortage problem. Policymakers need knowledge about retention/attrition in order to understand the factors contributing to career decisions and to develop appropriate policies for increasing the retention of special educators. This article reviews and critiques the retention/attrition literature relevant to special education and outlines considerations for future research and the development of retention policies. The importance of retaining qualified special educators becomes apparent when studying the shortage problem. Recent estimates indicate that an additional 29,774 special education teachers were needed to replace uncertified staff and fill vacancies in the U.S. during 1988-89 (The Thirteenth Annual Report to Congress, 1991). E.E. Boe (personal communication, 1991), using the Annual Reports to Congress, found that the need for fully certified special educators increased by more than 12,000 (or 74%) over a recent 4-year period, while the supply of new teacher graduates declined by well over 7,000 (34%).Another indicator of the shortage problem is the high number of state personnel reporting teacher shortages (Schofer 8c Duncan, 1986;Smith-Davis, Burke, & Noel, 1984). Recent projections by a national consortium of special education organizations suggest that the teacher shortage problem in special education will reach crisis proportions in the years to come (American Speech-LanguageHearing Association, 1989).
