A "National Qualifier" is an event or competition that determines which participants can advance to a national-level contest. These qualifiers are often held in various sports, academic fields, or other competitive areas, allowing individuals or teams to showcase their skills and earn a spot in prestigious national tournaments. Typically, the top performers at a National Qualifier will receive invitations to compete in the national championship, such as the National Championships in sports like track and field or swimming. These events are crucial for athletes and competitors aiming to gain recognition and further their careers.
