Concentric meets biweekly with district and school personnel to select cohorts of students who demonstrate attendance and discipline challenges. The additional personnel allows us to widen our impact and meet the needs of families as well as provides additional opportunities for us to interact with our families and enhance our relationships. Also, we are able to identify ways to address challenges that negatively impact these non-academic factors and utilize resources to fill gaps in support and services.”
