Anchor paper

In standards based assessment, authentic assessment and Holistic grading, a test response is assigned a numeric score against typically both a scoring rubric, or set of rules, and an example paper or two for each level. These examples are called anchor papers. A limitation of the use of anchor papers is that typically only one or two papers are used for any grade number. It is often difficult to match the wide diversity of responses against only one or two papers, and this is part of the problem in ensuring repeatability and agreement between different scorers on grading the same response.
