Absenteeism is a concern for all ages and grades, but different factors impact absenteeism in the early years. Pre-K (and Kindergarten) in some states is not mandatory and parents play a strong role in ensuring attendance in the early years, therefore strategies to reduce absenteeism must consider the role of the family. Several states and cities offer promising practices to decrease chronic absenteeism. Across these settings and approaches, partnership with families is a critical factor for success. This FastFact provides information on potential causes of absenteeism, examples from cities and states to address it, and available resources. (author abstract)
