Rigor is creating an environment in which each student is expected to learn at high levels, each student is supported so he or she can learn at high levels, and each student demonstrates learning at high levels (Blackburn, 2008).
The Teacher Leaders Network just released a review of Rigorous Schools and Classrooms: Leading the Way. http://teacherleaders.typepad.com/tln_teacher_voices/2010/08/rigorous-leadership.html
