Round Rock ISD (RRISD) classifies absences as excused or unexcused, with excused reasons including illness, death in the family, and school-related activities, but unexcused absences can lead to truancy prevention measures, including official letters and attendance plans for 3, 7, and 10+ unexcused absences within specific timeframes, and may result in court involvement and fines for persistent truancy. Students missing over 10% of a class's instructional days may also lose credit unless they complete an approved plan to meet the learning requirements.
