Summaries of Item-Level Response Rates for NAEP Assessments

The links below provide tables with data on missing responses, which are categorized as omitted or not reached. The tables list data for a third type of response as well: an "off-task" response. An off-task response is one that is unrelated to the question and considered inappropriate. It applies to constructed-response items only (never to multiple-choice items.)

In an effort to provide quality data, NAEP staff examine response rates for each item prior to scaling. Since response rates vary across subject areas and grades, a general guideline is used as a way to bring attention to any item requiring special consideration. Any item with an omit, not reached, or off-task rate greater than 10 percent is investigated further.
