The Center for IDEA Early Childhood Data Systems (DaSy Center) developed the DaSy Data System Glossary to help you know exactly what we mean when we use a term in our resources and the other work we do with states. For each term, the glossary gives the:

  • Definition: A brief explanation of what the term means
  • Source: A direct link to the source of this information or notation that the definition is “DaSy-developed”
  • DaSy Framework Component: The data-related topic(s) addressed in the DaSy Data System Framework to which the term relates

Click on a specific term below or scroll through the list of terms in alphabetical order. Note that the definitions of these terms are also linked throughout the DaSy website, with “pop-out” definition text for easy reference.
