Photo of Joe AgronFor more than a decade, American School & University has compiled its "Top 10" issue highlighting the biggest, best and most popular in education facilities and business. The issue has proven to be a favorite with readers; and one thing heard time and again is "give us more."

While the issue in your hands has a variety of Top 10 features, lists, products and more, we've added extra emphasis to the "more" by providing additional Top 10 lists in our Web 101 Exclusive section.

This issue also includes the annual Green Cleaning Award for Schools & Universities. Now in its third year, the competition has showcased some of the most innovative programs at education institutions nationwide. This year is no exception, and those institutions featured are setting the bar — and have created programs that other schools and universities can emulate and build upon to create more healthful, sustainable environments for learning.

Speaking of green and the Top 10, the U.S. Green Building Council recently compiled a list of the Top 10 states with the most LEED- (Leadership in Energy and Environmental Design) registered K-12 school and higher-education projects. The states that are leading the way:
