I hate the mantra, "No Excuses." Paul Tough recounted the more modest, original intention of the slogan, and observed that it can be hard to distinguish between an excuse and an explanation. When theorists, however, can not tell the difference between an "excuse" and a "reason," they might as well proclaim, No Rationality. Since the research on "No Excuses" schools by the Right and "High Expectations" on the Left has been repudiated, I see the continued use of the term as basically a method of keeping hard truths from being expressed.
My favorite memory of this dynamic has probably been embellished by repeated retelling, but I recall the young administrator who had only taught in suburban schools as he exhorted social studies teachers. "The high school excuse is to blame the middle school, which blames the elementary school, which blames the home, and then we are saying ..."
White teachers squirmed uncomfortably until a Black teacher said, "If you are blaming all these rednecks here, we’re cool, but ..."
The laughter temporarily slowed the administrator’s ardor, but he came back to the same old Education Trust message.
This time I derailed him with a joke, but the young idealist looked like characters in "Dr. Strangelove" as they struggled to keep their true feelings from bursting out.
