Superintendent Ash refocused Lexington school district on helping not the bussed-in Boston students but any student who needed extra help. He brought in nationally known trainers who helped teachers learn to collaborate and make better instructional decisions. As the collaboration took hold, not only did Lexington’s students coming in from Boston do better but all groups of students and Lexington shot to the top of the country in terms of academic achievement. As scholar Ron Ferguson says, “It can be done.”
