Teacher training impact report

Poor professional development fails students
U.S. schools need to improve teacher training to raise the effectiveness of the entire educational system, according to a new report from researchers at Stanford University. "We're way behind other countries that are high-achieving in terms of the time and intensive opportunity for deep learning they provide," said co-author Linda Darling-Hammond.. "We still see teachers engage in really short one- and two-day workshops rather than ongoing, sustained support that we now have evidence changes practices and increases student achievement."
