Evidence-based practice and evidence-informed practice are not just buzzwords in education. It is essential that administrators encourage both the development and the application of new knowledge in the field. This study of 1755 elementary age children in Central Texas indicates a positive association between the experience of childhood loss and grief and a diagnosis of AD/HD. Implications of this information for administrators in education are explored, including the training of counselors and classroom teachers in grief interventions and accommodations for grief related attention problems in children.
