Attendance Matters: Every Day Counts for Student Success

August 15, 2025 by webmaster

Welcome to another exciting school year at Southside ISD. It is wonderful to have all of our students back in the classroom. Providing a high quality education is of the utmost importance at Southside ISD. We believe school success goes hand and hand with good attendance. 

Southside ISD, believes that consistent attendance is one of the most important factors in a student’s academic and social success. When students are present and engaged, they build the skills, relationships, and knowledge needed to thrive both in school and beyond. Missing school—even just a few days—can have a lasting impact.

Why Attendance Is Important

  • Academic Growth: Students who attend school regularly are more likely to keep up with lessons, participate in class discussions, and master essential skills.
  • Social Connection: Being in school every day helps students develop friendships, teamwork, and communication skills.
  • Future Readiness: Regular attendance builds habits that prepare students for college, careers, and life after graduation.

How Families Can Help

  1. Establish Routines: Set consistent bedtimes and morning schedules to make getting to school on time easier.
  2. Plan Ahead: Schedule medical appointments outside school hours whenever possible.
  3. Stay Informed: Communicate with teachers and the school office if your child must be absent.
  4. Monitor Attendance: Review attendance regularly in the parent portal to ensure accuracy.

Every school day is an opportunity for learning, growth, and connection. Let’s work together to make sure every student is present, engaged, and on the path to success—because in Southside ISD, every day truly counts.

The Matthey MS Student Cardinal Spotlight goes to our 8th grader Tristan Abrego. TJ as he is known by his friends and family was the starting quarterback of our zone champion 8th grade football team.  TJ is a great student athlete.  He is a role model student who always strives to lead by example.  We look forward to great things from TJ in the near future.
