Contemporary educational theory holds that one of the pivotal causes of inadequate school performance is the inability of schools to adequately staff classrooms with qualified teachers. This theory also holds that these school staffing problems are primarily due to shortages of teachers, which, in turn, are primarily due to recent increases in teacher retirements and student enrollments. This analysis investigates the possibility that there are other factors-those tied to the organizational characteristics and conditions of schools-that are driving teacher turnover and, in turn, school staffing problems. The data utilized in this investigation are from the Schools and Staffing Survey and its supplement, the Teacher Followup Survey conducted by the National Center for Education Statistics. The results of the analysis indicate that school staffing problems are not primarily due to teacher shortages, in the technical sense of an insufficient supply of qualified teachers. Rather, the data indicate that school staffing problems are primarily due to excess demand resulting from a "revolving door"-where large numbers of qualified teachers depart their jobs for reasons other than retirement. Moreover, the data show that the amount of turnover accounted for by retirement is relatively minor when compared to that associated with other factors, such as teacher job dissatisfaction and teachers pursuing other jobs. The article concludes that popular education initiatives, such as teacher recruitment programs, will not solve the staffing problems of such schools if they do not also address the organizational sources of low teacher retention.

In recent years there bas been an increase in the number of programs offering support, guidance, and orientation for beginning teachers during the transition into their first teaching job. This study examines whether such programs-collectively known as induction-have a positive effect on the retention of beginning teachers. The data used in the analysis are from the nationally representative 1999-2000 Schools and Staffing Survey. The results indicate that beginning teachers who were provided with mentors from the same subject field and who participated in collective induction activities, such as planning and collaboration with other teachers, were less likely to move to others schools and less likely to leave the teaching occupation after their first year of teaching.

This review critically examines 15 empirical studies, conducted since the mid 1980s, on the effects of support, guidance, and orientation programs-collectively known as induction -for beginning teachers. Most of the studies reviewed provide empirical support for the claim that support and assistance for beginning teachers have a positive impact on three sets of outcomes: teacher commitment and retention, teacher classroom instructional practices, and student achievement. Of the studies on commitment and retention, most showed that beginning teachers who participated in some kind of induction had higher job satisfaction, commitment, or retention. For classroom instructional practices, the majority of studies reviewed showed that beginning teachers who participated in some kind of induction performed better at various aspects of teaching, such as keeping students on task, developing workable lesson plans, using effective student questioning practices, adjusting classroom activities to meet students' interests, maintaining a positive classroom atmosphere, and demonstrating successful classroom management. For student achievement, almost all of the studies showed that students of beginning teachers who participated in some kind of induction had higher scores, or gains, on academic achievement tests. There were, however, exceptions to this overall pattern -in particular a large randomized controlled trial of induction in a sample of large, urban, low-income schools -which found significant positive effects on student achievement, but no effects on either teacher retention or teachers' classroom practices. Our review closes by attempting to reconcile these seemingly contradictory findings and also by identifying gaps in the research base, and relevant questions that have not been addressed and warrant further research. teacher commitment and retention, teacher classroom instructional practices, and student achievement.

Has the elementary and secondary teaching force changed in recent years? And, if so, how? Have the types and kinds of individuals going into teaching changed? Have the demographic characteristics of those working in classrooms altered? To answer these questions we embarked on an exploratory research project to try to discover what trends and changes have, or have not, occurred in the teaching force over the past few decades. We were surprised by what we found. We discovered that the teaching force has been, and is, greatly changing; yet, even the most dramatic trends appear to have been little noticed by researchers, policy makers, and the public.

Contemporary educational thought holds that one of the pivotal causes of inadequate school performance is the inability of schools to adequately staff classrooms with qualified teachers. It is widely believed that schools are plagued by shortages of teachers, primarily due to recent increases in teacher retirements and student enrollments. This report summarizes a series of analyses that have investigated the possibility that there are other factors-tied to the organizational characteristics and conditions of schools-that are behind school staffing problems. The data utilized in this investigation are from the Schools and Staffing Survey and its supplement, the Teacher Followup Survey conducted by the National Center for Education Statistics. These data indicate that school staffing problems are not primarily due to teacher shortages, in the sense of an insufficient supply of qualified teachers. Rather, the data indicate that school staffing problems are primarily due to a "revolving door"-where large numbers of qualified teachers depart their jobs for reasons other than retirement. The data show that the amount of turnover accounted for by retirement is relatively minor when compared to that associated with other factors, such as teacher job dissatisfaction and teachers pursuing other jobs. This report concludes that teacher recruitment programs-traditionally dominant in the policy realm-will not solve the staffing problems of such schools if they do not also address the organizational sources of low teacher retention.

Contemporary educational theory holds that one of the pivotal causes of inadequate school performance is the inability of schools to adequately staff classrooms with qualified teachers. Contemporary theory also holds that these staffing problems are primarily due to shortages of teachers, which, in turn, are primarily due to recent increases in teacher retirements and student enrollments. This analysis investigates the possibility that there are other factors that might have an impact on teacher turnover levels, and, in turn, the staffing problems of schools, factors rooted in the organizational characteristics and conditions of schools. The data utilized in this investigation are from the Schools and Staffing Survey and its supplement, the Teacher Followup Survey, a large, comprehensive, nationally representative survey of teachers and schools conducted by the National Center for Education Statistics. The results of this analysis show that, net of teacher effects, there are significant effects of school characteristics and organizational conditions on teacher turnover which have largely been overlooked by previous research. For example, the data show that while high-poverty public schools have moderately higher rates, contrary to conventional wisdom, neither larger schools, nor public schools in large school districts, nor urban public schools have especially high rates of teacher turnover. In contrast, small private schools stand out for their high rates of turnover. Moreover, the data show, again contrary to popular wisdom, that the amount of turnover accounted for by retirement is relatively minor, especially when compared to that resulting from two related causes -teacher job dissatisfaction and teachers pursuing other jobs. The data show that, in particular, low salaries, inadequate support from the school administration, student discipline problems, and limited faculty input into school decision-making all contribute to higher rates of turnover, after controlling for the characteristics of both teachers and schools. The results of this investigation suggest that school staffing problems are neither synonymous with, nor primarily due to, teacher shortages in the conventional sense of a deficit in the supply of teachers. Rather, this study suggests that school staffing problems are primarily due to excess demand resulting from a "revolving door" -where large numbers of teachers depart their jobs for reasons other than retirement. This study also suggests that popular education initiatives, such as teacher recruitment programs, will not solve the staffing problems of such schools if they do not also address the organizational sources of low teacher retention.

This article investigates the possibility that the organizational characteristics and conditions of schools are driving teacher turnover. The data used in this investigation comefrom the Schools and Staffing Survey and its supplement, the Teacher Follow-up Survey, conducted by the National Center for Education Statistics (NCES, 1996). This analysis indicates that the amount of turnover accounted for by retirement is relatively minor when compared with that associated with otherfactors such as teachers'job dissatisfaction and teachers'pursuit of otherjobs. In fact, school staffing problems are not principally due to teacher shortages; they do not seem to stem from an insufficient supply of qualified teachers butfrom an excess demand. The data indicate that a revolving door exists, that large numbers of qualified teachers are departing their jobs for reasons other than retirement. Popular education initiatives, such as teacher recruitment programs, will not solve schools' staffing problems if they do not also address the organizational sources of low teacher retention.

In recent years there has been a growing interest in support, guidance, and orientation programs-collectively known as induction-for beginning elementary and secondary teachers during the transition into their first teaching jobs. This study examines whether such supports have a positive effect on the retention of beginning teachers. The study alsofocuses on different types and components of induction, including mentoring programs, collective group activities, and the provision of extra resources and reduced workloads. The results indicate that beginning teachers who were provided with multiple supports, were less likely to move to other schools and less likely to leave the teaching occupation altogether after their first year. Some forms of assistance and support, however, did not appear to increase beginners' retention.
