WaKIDS, the Washington Kindergarten Inventory of Developing Skills, includes an assessment that is administered during the first two months of kindergarten. Teachers observe students across six areas of development and learning; Social-Emotional, Physical, Language, Cognitive, Literacy and Math. While the only requirement for kindergarten is to be five years of age by August 31, children who demonstrate readiness in all six areas have a greater likelihood of success in kindergarten and beyond.
