Anti-truancy efforts are not new, but there are powerful new incentives which are now spurring school officials' interest in keeping students in class and their school. Not only does the "No Child Left Behind" Act require schools to boost student attendance and lower dropout rates, schools will never be able to succeed in meeting the law's Annual Yearly Progress goals if students are not in class learning. In this article, the author discusses some examples of those school districts across the nation that have launched more rigorous programs to crack down on students who are missing valuable information time and are at increasing risk of dropping out of school altogether. Moreover, the author elaborates on the new ways and some reasons to fight truancy.
