If I were ever asked to coordinate a schoolwide grading system change again, I would take a cue from the authors of Data Wise: A Step-by-Step Guide to Using Assessment Results to Improve Teaching and Learning (2013). In Chapter 6, this gem of a statement reads…

“It is easy to achieve consensus on solutions that do not require teachers to make changes in their day-to-day practice, even when data show that such practices are consistently ineffective.” (pp. 140-141)
