Until 2015, Anne Arundel County Public Schools used the Maryland Model for School Readiness assessment as an early measure of child development and social and emotional readiness for kindergarten. Using that measure, from 2007-2014 Anne Arundel County’s readiness figures increased from 69% to 86%, although students scoring lowest were the low-income and English Language Learners at 78% and 72% respectively. (Maryland State Department of Education, 2014). In 2015, a new kindergarten readiness tool was introduced; Ready4Kindergarten or R4K. The tool includes an Early Learning Assessment that measures the progress of learning in young children (36 months to school age) and the Kindergarten Readiness Assessment (KRA). The readiness scores for 2015 cannot be compared to 2014 because the two tests are entirely different. Pre-kindergarten and kindergarten students are showing an increase in behavior problems at every income level and every geographic area (AACPS, 2015.) Children’s mental health and behavioral issues, especially for infants and toddlers, are a continuing need in the county. The Behavioral and Emotional Supports and Training program (BEST,) is a promising practice. It is the only behavior management program for the 0-5 population in the county. It is considered by many to be a national model for working with young children with emotional and behavioral problems and autism. BEST is coordinated by Anne Arundel Community College’s TEACH Institute & Parenting Center. Behavior Specialists provide behavioral and emotional support and training to parents and child care providers for children exhibiting challenging behaviors.
