Quotes: Let's Focus On Schools (Forests), Not Teachers (Trees), Says Kingsland
It takes an exceptional teacher to marginally increase a student’s test score, and these gains fade out quickly. It takes an average urban charter school to increase a student’s test score, and these gains increase over time. Lastly, test scores aren’t everything, so we should be cautious in how we use them and we should give strong deference to parental choice.
