This self-study guide provides state and local education agencies and schools with a tool to assess the implementation of career readiness practices across a district or secondary school and to plan improvements. It is arranged by implementation areas that have been found to be important to career readiness efforts based on a review of the literature and discussions with stakeholders. Each area includes guiding questions for discussion, potential sources of evidence, and a rating scale for self-assessment of implementation. This process of ongoing discussion, evidence use, and self-assessment can help states, districts, and secondary schools improve the effectiveness of career readiness practices.
