To ensure consistency in the conduct of assessments, NAEP prescribes procedures that must be completed by field staff before, during, and after each assessment. Doing so helps ensure high data quality and that legal requirements are met, as well as minimizes the risk that any required data collection form is incomplete or unreturned. These routines are formalized in the Quality Control Booklet, one of which is completed by field staff for each grade at each sampled school (i.e., two Quality Control Booklets are completed for a school having two sampled grades).
Supervisory site visits and telephone follow-up with schools are intended to quickly identify and diagnose any potential problems with field staff teams. The quality of NAEP assessment data depends on having thoroughly trained data collectors possessing the knowledge, skills, and abilities to successfully prepare for and conduct assessments. Frequent monitoring ensures compliance with procedures. In-person visits permit many of the most experienced field staff members, along with contractor and National Center for Education Statistics personnel, to observe staff performance. Telephone follow-up calls with a subset of assessed schools permit efficient identification of any potential problems, and, if necessary, permit NAEP to restore positive relationships with schools that may be again sampled for future assessments.
