"Value-added" is an unfortunate term. It suggests that we’ve measured the sum of all that teachers contribute or the sum of their value, which is dehumanizing as well as inaccurate.

The Every Student Succeeds Act presents a challenge and an opportunity. It changes the question from “what do we have to do?” to “what new opportunities exist?” as states can now design their accountability systems to accomplish their own goals rather than complying with federal demands.

In a recent post on the Brookings Brown Center Chalkboard, Helen Ladd urges states to experiment with replacing test-based accountability with school inspections, visits by trained experts who rate the schools they visit and then issue reports.

The academic achievement gap in the United States is large. A low-income child has less than a 1 in 10 chance of graduating from college, compared to nearly 8 in 10 high-income children.

How do we identify great teachers and help all teachers improve their craft? The best option may be to combine student growth measures, observations of teachers in the classroom, and student surveys.

Does high-stakes evaluation scare teachers away? And if so, which teachers? Does this help or harm students? High-stakes evaluation does affect who comes into the classroom and who stays there, and research indicates that this flux may actually be good for students.

The world of education is becoming inundated with data, and the growing use of technology in schools has made it even easier to collect and report data continuously.
