Nearly a million teachers will reach retirement age in the next 9 to 11 years. This report presents a complete state-by-state overview of the retirement programs available to America's teachers. Chapter 1 presents the issues of teacher aging, retirement, and early retirement and asks how school districts might effectively manage the retirement and replacement of teachers. Chapter 2 surveys retirement plans in the 50 states and provides information on how to calculate a teacher's pension, with relevant data by state. Chapter 3 looks at local and state programs to entice teachers to retire early. Empirical methods are used to assess the effectiveness of various plans. Case studies of early retirement incentive plans in six districts show how these plans work. Based on conclusions drawn from these data, school officials are advised on how to create, implement, and evaluate an early retirement program. Chapter 4 calls for a national task force on teacher retirement and argues that the future of the teacher retirement system depends on resolving six related issues: (1) threatened financial viability; (2) lack of consistency between local and state policies; (3) lack of portability of plans; (4) lack of system flexibility in investment and withdrawal of funds for teachers; (5) lack of control by teachers as individuals and as a group; and (6) lack of equity among teachers in various districts.
