The Center for IDEA Early Childhood Data Systems (DaSy Center) developed this 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 (for more information about the DaSy framework, visit dasycenter.org/resources/dasy-framework)
