Each of the thousands of school districts and millions of classrooms in the United States has its own unique set of challenges that reflect a wide diversity of students, teachers, resources and communities.

Yet each school system also confronts similar facilities and business issues that cut across differences in population, geography and wealth. Is there enough space for every student? Will there be enough teachers to guide them? Do the buildings enhance learning, or is inadequate design and deterioration hurting student performance?

Once you decide to start a list of these issues, it could go on at some length. With a bow to the decimal system, this article will stop at 10. These are among the top issues that continually crop up as challenges for schools to overcome or goals to achieve. These might not be the top priorities for every district, but at some point, most schools will have to decide how to address them.
