The National Shoot to Retrieve Association is an organization of bird dog hunters in the United States. NSTRA is a non-profit origination that conducts sanctioned field trials across the country. NSTRA is divided into 30 regions that compete in local and national field trials.NSTRA sanctioned Field Trials are open to all pointing breed dogs and are conducted under conditions closely resembling actual wild bird hunting. In field trials two dogs compete against each other for points. Five quail are put into a field and the two dogs hunt the field to point the birds. The dogs are scored on how well they perform in the field. The dogs are judged on ground coverage, obedience, points, retrieves, and backs.
