Schools are remarkably insular institutions, so "Have I improved?" is an especially difficult question for principals. Sure, schools are filled with people. Despite the schoolwide assemblies, faculty meetings, and crowded halls, much of what principals do is unseen and unknown by other adults. A big portion of principals' time is spent in individual or small-group meetings; working on the computer (writing reports and feedback from observations); supporting committee work; or e-mailing--as well as playing the important yet superficial roles of monitor, greeter, and tour guide. Because much of what principals do isn't obvious to others, the comments they get about their performance are often unhelpful (plus, people are quicker to complain than to compliment). Since leadership is based on relationships, and principals need to be assured that they have strong relationships with colleagues, periodically asking how they perceive a principal's leadership is an essential step.This article provides some specific suggestions for reaching out to colleagues for helpful feed back.
