Lisa Gartner at the Washington Examiner reports that Fairfax County Virginia will now base 40 percent of teacher evaluations on student “achievement”. This was the minimum they were able to use under New Child Left Behind.
What the phrase student achievement means and how it is measured seems to be flexible. There is also a teacher role in setting what the student goals are for each individual teacher it appears.
From what I gather from the article, measuring the 40 percent student achievement part itself may not be directly from test scores. Nor does the performance have to tie in directly to core standards for example.
Thus learning the Peano Axioms and the definition of addition of natural numbers, which is not on the exams could be made a goal, and if the students learned the 5 axioms and the definition of addition, they would have made student achievement is how I read it.
== Quote from Performance Evaluations Page
The Fairfax County Public Schools performance assessment process and evaluations are designed to provide all employees with increased opportunities for professional growth and development. This process is based on a supervisory cycle of reflection, observation, and discussion that leads to employee improvement.
Employees are assessed from the beginning of service and the results are reported regularly in an evaluation. Discussions regarding performance occur between the evaluator and the employee throughout the process. Employees have multiple opportunities to refine or enhance their skills.
