Roanoke County Public Schools superintendent Dr. Ken Nicely shares an important message about attendance. Virginia defines chronic absenteeism as missing 10% or more of the school year, regardless of the reason for the absence. Parents and guardians, thank you for working with us to make sure children are in school each day. Being present positively correlates to academic success and develops an Opportunity Ready habit of showing up to school and work on time. #ShowUp4Success.
