Quality Control

The NAEP data analysis process requires that a random sample of booklets and corresponding scores or scoring sheets be pulled for an additional quality control check. For image-scanned documents, a scoring sheet is not used, so the data analysts use scores sent to them on a data tape from the scoring center to verify the accuracy of applied scores. All of the documents are selected prior to sending the booklets to storage and are then sent to the data analysts to verify the accuracy and completeness of the data. A random sample of all the questionnaires used in the assessment is also sent to the analysts. Upon completion of the quality control check, the analysts ship the materials to the NAEP materials staff for permanent storage.
