Duncan praised Hickenlooper and DPS Tom Boasberg for the success story.

“Turning around under-performing schools is probably the hardest, most controversial, but most important work that we as a nation are doing,” said Duncan. “No one is doing this perfectly. We’re learning every single day but these guys are getting a heck of a lot right.”
