September 28, 2011 – Bryan Hassel spoke at the 2011 PIE Network Summit: Taking Stock on Teacher Quality Reforms: What’s been accomplished in 2011? What’s next? When asked about the biggest gains made over the past five years,  Hassel said there has been a huge increase in understanding the difference in effectiveness among teachers and the impact the best ones have on improving student achievement. By redesigning jobs and using technology, Hassel argued, “we could enable excellent teachers to reach three-fourths of students or more.”
