Efforts to better prepare students for success beyond high school depend on them being in class to receive instruction and experience all opportunities available at their schools . Data on chronic absenteeism and discipline , however , show too many students miss too much time in school . Students who are absent 10 percent of school days
( 18 days ) or more miss valuable instructional time and often struggle to stay on pace in their learning . This chronic absenteeism contributes to achievement gaps between economically disadvantaged students and their peers from higher-income backgrounds . 8 Economically disadvantaged students are three times as likely to be chronically absent , with their reduced opportunity to learn compounding other challenges in raising their achievement .
