Washington Kindergarten Inventory of Developing Skills (WaKIDS)

The Washington Kindergarten Inventory of Developing Skills (WaKIDS) is a transition process that helps to ensure a successful start to the K-12 experience and connect the key adults in a child’s life.

In addition, WaKIDS provides a snapshot of where Washington's kindergartners are in their development early in the school year. These data help inform state and district-level decisions about education policy and investments, and classroom decisions about individualized learning. WaKIDS is legislatively mandated to be part of state-funded, full-day kindergarten (RCW 28A.150.315 and RCW 28A.655.080). 

The Three Components of WaKIDS

  1. Family connection welcomes families into the Washington K-12 system as partners in their child’s education.
  2. Whole-child assessment helps kindergarten teachers learn about the skills and strengths of the children in their classrooms so they can meet the needs of each child.
  3. Early learning collaboration aligns practices of early learning professionals and kindergarten teachers to support smooth transitions for children.

Linking Kindergarten & 3rd Grade Assessment Results

Data from WaKIDS and Smarter Balanced Assessments (SBA) indicate a correlation between kindergarten readiness and meeting 3rd grade math and English Language Arts (ELS) standards.

Children who start school behind tend to stay behind. Knowing more about children’s entering skills and strengths helps teachers and parents work together to support student growth in the kindergarten year.

WaKIDS 2019-20 Results

WaKIDS assesses incoming kindergartners' readiness in six domains: social emotional, physical, language, cognitive, literacy and math. Kindergarten readiness is based on readiness in all six domains. The WaKIDS 2019-20 Kindergarten Readiness Results are consistent with trends from previous years.
