Armed with research about a teacher’s impact on student achievement, policy makers have required states and school districts to evaluate their teaching force, and the most readily available data has been standardized test scores. Passage of the Every Student Succeeds Act effectively back-tracked on this accountability strategy. No longer is there a federal mandate that schools evaluate teachers. And those that do will not be required to base their analysis on scores.

But former superintendent, principal and teacher Lisa Andrejko does not believe such evaluations will become a thing of the past.

“With so much time and effort undertaken at the state level in the implementation of accountability measures such as Student Learning Objectives (SLOs), prescribed teaching standard frameworks or rubrics and student achievement data, I cannot imagine a scenario in which states would abandon their new methods for grading teachers,” Andrejko wrote for PeopleAdmin in May. She expects revisions, but not necessarily another overhaul.

Still, ESSA creates a level of freedom that some districts may find exciting. The law provides for the use of federal dollars to survey teachers about working conditions and offer professional development, professional growth and leadership opportunities. And, importantly, it offers an opportunity to recalibrate after the last 15 years of No Child Left Behind.

Anne Udall, executive vice president of program strategy at the nonprofit New Teacher Center, hopes district administrators stop and think carefully about where to take teacher evaluations in the coming years. NCLB attached accountability to test scores, primarily, and Udall says research clearly shows that is not a useful way to gauge educator effectiveness.

“My hope with ESSA is that we’ve learned enough from what didn’t work that we’re going to try to find the more comprehensive, nuanced approach,” Udall said.

What, then, should this new approach entail?

Udall and Andrejko agree evaluations should be used to help teachers improve their craft. That means they have to come with more nuanced feedback and targeted professional development. While many advocates of test-based accountability demanded it to weed out the worst teachers, advocates of new teacher evaluation systems aim to use it as a tool for improvement.

How administrators can adapt

Administrators, in this new design, will need to sharpen a few skills of their own.

“You can know what great instruction looks like, but you may not have the skillset to mentor or coach a new teacher because you don’t know how to tell them what they’re doing well and what they’re doing poorly,” Udall said.

Professional development for administrators should cover strategies for recognizing high-quality instruction as well as providing useful feedback.

In many schools, even carving out the time for regular classroom observations will require a major shift. This is where district administrators come in. Central office leaders can provide the support that frees principals from other management duties, delegating administrative tasks to other staff members and leaving principals to focus on staff development.

One trend the New Teacher Center has identified is the formation of instructional leadership teams in schools. These groups bring together principals, vice principals, department chairs and teacher representatives into a learning community that focuses on how best to support teacher improvement, design evaluation systems and approach coaching.

After years of watching evaluation be used as a tool to “sort and punish,” Udall is excited to see a new trend of using evaluations to support teacher growth.

A lot is still up in the air when it comes to ESSA. But as the Obama administration finalizes its rule-making and states decide how to proceed, school districts can set their own priorities for evaluation, at least. Now no longer required by federal law, it can provide the foundation for effective school improvement that focuses on bringing out the best in today’s teachers.
