• How is the KDI-2 typically administered?
  • The KDI-2 is typically administered by a kindergarten screening team where the child rotates from station to station to completethe tests.
  • The KDI-2 may also be individually administered by a trained examiner (e.g., school psychologist, educational diagnostician, speech therapist, etc.) to evaluate an individual child's developmental readiness skills as part of a comprehensive individual evaluation.

• How is the KDI-2 scored?
  • The KDI-2 may be scored using the standardization sample norms in the KDI-2 Administration Manual, but it is best scored using local or national norms calculated by the KDI-2 Scoring and Interpretation Program for Windows™.

• Is the KDI-2 a diagnostic or prescriptive test?
  • The KDI-2 can best be described as a diagnostic and prescriptive assessment tool for early identification of pre-academic skills.
  • The KDI-2 is diagnostic because it is a good predictor of future academic learning.
  • The KDI-2 is also a good screener for potential developmentally delayed children and potentially gifted children on either end of the developmental readiness continuum.
  • The KDI-2 may be used prescriptively to identify a child's strengths and weaknesses across the 13 developmental readiness tests and link interventions to the child's educational needs.
  • The KDI-2 should be used in conjunction with some prescriptive linkage such as the activities in My Kindergarten Fun Book-2.
