This paper presents the Ohio edition of the National Council on Teacher Quality's 2008 "State Teacher Policy Yearbook". The 2008 "Yearbook" focuses on how state policies impact the retention of effective new teachers. This policy evaluation is broken down into three areas that encompass 15 goals. Broadly, these goals examine the impact of state policy on 1) identifying effective teachers, 2) retaining those deemed effective and 3) exiting those deemed ineffective. Overall, Ohio has done a good job in meeting some goals; however, significant room for improvement remains in several others. The state completely missed five goals, met a small portion of one, partially met one, nearly met five and fully met three. Ohio's best performances are its requirement of multiple formal evaluations for new teachers and its support of differential pay in shortage subject areas and high-needs schools, and performance pay. The state has the most work to do on making tenure decisions meaningful, articulating consequences for teachers with unsatisfactory evaluations and strengthening some policies regarding teacher compensation issues. Ohio's progress toward meeting these goals is summarized. The body of the report provides a more detailed breakdown of the state's strengths and weaknesses in each area. Ohio has an overall performance of C for 2008. Goals for each area are appended. (Contains 57 figures.)
