The Center for Education Policy released a report this week that analyzes the changes in curriculum and instruction time since the enactment of No Child Left Behind (NCLB). “Choices, Changes, and Challenges: Curriculum and Instruction in the NCLB Era” finds that since the enactment of NCLB, 62 percent of school districts increased the amount of time spent in elementary schools on subjects that are tested for accountability, while 44 percent of school districts cut time on science, social studies, art and music, physical education, lunch, or recess.
