In the past decade, at least 80 US school districts have delayed their high school start times, and perhaps double that number are weighing such a change, according to informal reports to the National Sleep Foundation (NSF). While some parents worry students may stay up later, that has not happened in other school systems that have made such schedule changes. Studies show that when school starts later, students not only get more sleep but also contribute more to class discussions, doze in class less often, arrive tardy less often, miss fewer days, visit nurses and counselors less often, report less depression and irritability, and have fewer driving crashes.
