The Nordic Weightlifting Federation uses Q-points to determine the Best Lifters at Nordic Championships, both for Seniors and Juniors (U20), with slight restrictions to the lowest bodyweight categories (see text below).
Update November 15, 2025 at the Congress in Gardabaer, ISL:
The lowest bodyweight to consider is 50 kg for male lifters and 41 kg for female lifters. These numbers include all results from all IWF U17 World Championships. This means that a male lifter weighing a weight under 50,0 kg will use the coefficient for 50,0 kg; a female lifter weighing a weight under 41,0 kg will use the coefficient for 41,0 kg.

A group consisting of Dr. Marianne Huebner, David Meltzer, Asgeir Bjarnason, and Aris Perperoglou have published a paper on their work which explains the method and compares the Q-points with Sinclair points and discusses short comings of Robi points.

Q-points scaling table is recommended for athletes 18 years and older. The challenge with using the Q-points scaling system with youth lifters is in the comparison of pre-teen athletes to athletes who have gone through puberty. If one holds a youth competition and wants to determine the best lifter, one can compare the same aged lifters to each other: the best 12-13-year-old lifter; the best 14-15-year-old lifter; and lastly the best 16-17-year lifter.
Update September 2024:
Dr. Marianne Huebner has lead work on another scaling system, GAMX, which is suitable for athletes ages 13-17. However, the comparison between the age groups is still recommended to compare 13-year-olds with other 13-year-olds, and to compare 14-15-year-olds as well as 16-17-year-olds to their peers. GAMX is also suitable for direct comparison between men and women.
