Most years, the Northwest Section hosts three championship meets, two senior level meets and one age group meet.
USA Swimming/Speedo Champions Series Western Region Section SC Championship, colloquially known as Senior Sectionals, is held once in the short course season and once again in the summer for long course season. This championship meet is open to any swimmer who meets the qualifying time, regardless of age. During the 2007-2008 season, Senior Sectionals was changed. The short course meet was held in December and the long course meet was held in April.
Northwest Section Age Group Championships, also known as Age Group Sectionals, are held once a year during short course season, usually in March. The meet is open to swimmers 18 and under who have not qualified for Senior Sectionals.
