North Texas

After-School All-Stars (ASAS) North Texas is devoted to the improvement and empowerment of all-inclusive education. One example would be Edward H. Cary Middle School (Cary Middle School), which had been identified as an “Improvement Required” school by the state. ASAS North Texas launched at Cary Middle School in 2014 with a mission to partner with the school’s academic staff to improve overall student performance. The school had experienced significant turnover in leadership and faculty and needed a partner to engage and develop students through enrichment. Since ASAS North Texas launched at the school and worked closely with teachers and staff to provide students with more than academic support after school, Cary Middle School has since then renounced their “Improvement Required” status.

ASAS North Texas strives to provide a sense of continuity with all program activities. The site coordinator and program staff partner together to familiarize themselves with each student’s personal needs. This collaboration has allowed for a strong partnership to emerge between the school and ASAS North Texas program staff. Through continued collaboration, ASAS North Texas works with the school administration to ensure all partnership goals are aligned to enhance academic and social-emotional learning. Both ASAS and the school staff communicate proactively to provide students with the necessary skills for advancing successfully through middle school and beyond. Our hope is to provide students with the necessary enrichment programs to develop their own individual skillsets.
