According to the American School Counselor Association, the foundation of a robust, comprehensive school counseling program is data. Our whole school (Tier 1), group (Tier 2) and individual (Tier 3) interventions should be based on relevant data. This data comes from sources that we, as school counselors, have reviewed (discipline, attendance and achievement scores) or collected ourselves (pre/post assessments, surveys and classroom lesson data). The information taken from this data should be the driving force when collaborating, coordinating and consulting with our administrators, colleagues and other stakeholders. Data can also help us advocate for fewer non-school-counseling duties. Unfortunately, for those not trained in data collection and interpretation in graduate school, this can seem like an overwhelming and intimidating task.
