You, forward-thinking school leader, have laid your best plans for developing your staff. Instructional coaches: check. Comprehensive teaching rubric: check. But unless you can move the needle on mindset, you won't make much progress. "Mindset" is Carol Dweck's term to describe the spectrum of attitudes that people have towards their ability to improve.
