The Long-Term Impact Of Great Teachers
The impact of great teachers is impossible to measure, but that doesn’t keep some folks from trying.
How we measure that impact gets at the heart of assessment and accountability, two issues at the core of ed reform worldwide.
The following infographic takes a look at the impact of teachers from the perspective of academic success, salary, and anecdotal responses from celebrities. A limited viewpoint, perhaps, but an interesting skim to keep the discussion going on how great teachers can literally change the world.
Note: The $25,000 average increase in lifetime cumulative income is an estimate based on an approximately 1% earnings increase at age 28 for students who had one standard deviation improvement in teacher value-added for one year between 4th and 8th grade.
