||Improve preparation, recruitment, development, evaluation, and
rewarding of effective teachers, principals, and administrators.
||In light of the importance of teachers and school leadership
for student success, the nation has to do more to ensure that
every student has an effective teacher, every school has
effective leaders, and every teacher and leader has access to
the preparation, on-going support, recognition, and
collaboration opportunities he or she needs to succeed. |How
progress is measured: ||Number of states reporting that any
school districts are evaluating the performance of teachers that
include student growth as an evaluation criterion |Why is this
measure important? ||Research consistently finds that teacher
effectiveness is the most important in-school factor in student
learning, but existing evaluation systems generally do not
meaningfully differentiate teachers by their effectiveness in
improving student learning, and do not provide information and
feedback to teachers and school leaders
