The following is about the qualification rules and the quota allocation for the biathlon at the 2018 Winter Olympics.
[1] A total quota of 230 athletes are allowed at the Games (115 both men and women).
The first 218 quota allocations will be assigned using a combination of the Nation Cup scores of their top 3 athletes in the individual, sprint, and relay competitions, during the 2016–17 Biathlon World Cup season.
An athlete also must meet requirements before competing: During the 2016/17 or 2017/18 Biathlon World Cup season the athlete must have two results at IBU Cup, Open European Championships, World Championships or World Cup in the Sprint or Individual that at a maximum is 20% behind the average time of the top three athletes.
Or, two placings in the top half at the Junior World Championships.
