This study uses a secondary analysis of the Schools and Staffing Surveys (SASS) and Teacher Follow-up Survey (TFS) from the National Center for Education Statistics to examine relationship between teachers' perception of de-professionalization and demoralization and turnover in the accountability policy era from the mid-1990 s through mid-2000 s. Hierarchical linear modeling was applied to compare changes in this relationship across time and between public and private school teachers. Results show that the relationship of teacher de-professionalization to turnover significantly decreased during the accountability policy period, while the relationship of demoralization to turnover significantly increased during the accountability policy time period.
