The Paralympic Games is a celebration of athletic achievement for those with physical disabilities. It has been marred by a growing concern: “classification doping,” (which borrows language used to describe performance enhancing substance abuse). Athletes are misrepresenting the extent of their disabilities to gain an unfair advantage over competitors.

Double amputee Oksana Masters, a prominent Paralympic athlete, believes officials are more interested in maintaining a positive image than addressing the issue. "They want to keep the warm and fuzzy narrative going," she said. "If they knew what's really going on behind closed doors, they'd be shocked."

The Paralympic classification system is designed to place athletes into competitions with others who have similar impairments. While some disabilities are easy to categorize, others are more ambiguous, relying on the judgment of medical classifiers and the integrity of the athletes themselves.

The most infamous Paralympic cheating scandal came at the 2000 Sydney Games, where Spain’s intellectual disability men’s basketball team won the gold medal despite fielding a roster with 10 players who did not have disabilities.

Physician Kevin Kopera, a volunteer in the Paralympic classification system, is cautious about dismissing the issue. "I don't believe anyone can say to what degree misrepresentation exists in parasports," he said. "Any statement in this regard would be speculative. Certainly, to say it doesn't exist would not be realistic. The stakes are too high."
