In the context of Oklahoma's education system, what does PL 221 refer to?

PL 221 refers to a law in Oklahoma that pertains specifically to teacher accountability and evaluations. This legislation was designed to establish more rigorous standards for evaluating teachers' performance, including the implementation of annual evaluations that consider multiple factors, such as student performance and professional growth. The focus on accountability aims to ensure that educators are effectively contributing to student learning and achievement. This results in a more structured approach to assessing the effectiveness of teachers within the state’s education system, which ties directly into wider efforts to improve educational outcomes for students.

The other options do not accurately capture the scope of PL 221, as it does not primarily focus on student assessments, curriculum standards, or parental involvement, although these aspects are also important in the broader context of education policy.
