NASS ZONE CENTER QUALITY CONTROL MANUAL, JANUARY 1981

The purpose of the National Accident Sampling System (NASS) is to produce accurate statistics on the national motor vehicle accident picture and to provide a data base for the development and evaluation of motor vehicle and highway safety standards. The final system will consist of 75 small teams of accident investigators situated throughout the Continental United States. Within the NASS, zone centers have been established to quality control the CSS and special study data which are collected by the primary sampling unit teams. The purpose of this manual is to describe the administrative strategies and procedures used by the NASS zone centers to assure PSU sampling procedures are being followed and to control the accuracy, completeness, consistency from team to team, and timeliness of submission of the traffic accident data collected.
