Description | The Early Development Instrument is a questionnaire completed by kindergarten teachers in the second half of the school year that measures children’s ability to meet age-appropriate developmental expectations. It should be used as a population-level screener to assess change or status here, rather than to derive scores for individual children. |
Example | Would you say that this child comforts a child who is crying or upset? |
