Championship Points are awarded to players based on their finish position or placement at individual events. Championship Points are used to gain entry into high-level events, including the annual Pokémon World Championships. Event qualifications are listed on each event-specific page as it is posted.
Note that TCG Championship Points and VG Championship Points are considered separate. They cannot be used across event types. This means that players cannot use Championship Points earned at the Video Game Regional Championships to gain entry to the TCG World Championships. You can see how many Championship Points you've accumulated during the season on your Pokémon Trainer Club account profile page.
