NOTE: The Oklahoma State Games in 2018 are a qualifying games for the 2019 National Senior Games to be held in Albuquerque New Mexico.
To participate in the National Senior Games, you must be 50 years old and qualify the year before through a NSGA sanctioned State Qualifying Games. You may qualify through the state you live in, or any state which allows out-of-state competitors; however, you should contact these States directly for qualifying information. A complete list of sanctioned State Organizations with contact information and web link (if provided) is available on the website on the State Games page.
Qualifying standards differ depending on the sport/event and you should read more information about qualifying in the 2019 National Senior Games Rulebook posted under the link, 2019 NSGA Rulebook. Typically, the qualifying standards do not differ drastically from year-to-year.
In most sports, the top 4 finishers in each age group qualify for Nationals, as well as those who meet the Minimum Performance Standards (in applicable sports). The exceptions are Tennis (only the top 3 finishers for each age group qualify), Golf (you must meet the Minimum Performance Standards) and Triathlon (all finishers qualify). For team sports (basketball, softball, volleyball) the top 3 teams in each age group qualify. Demonstration sports do not require qualification. Qualifying for the 2019 National Senior Games will not begin until January 2018.
No matter what place an athlete finishes, they may also qualify in the sports which have Minimum Performance Standards (MPS), by meeting or exceeding the MPS for the age-division they are competing in at the State Level. (Ex. An athlete is 54 in 2018 and competes in the 50-54 age division at their State Games, but will move up to the 55-59 age division at Nationals. They must meet the MPS for the 50-54 age division to qualify for Nationals.
