[6] Because of issues in objectively identifying functionality that plagued the post Barcelona Games, the IPC unveiled plans to develop a new classification system in 2003.
This classification system went into effect in 2007, and defined ten different disability types that were eligible to participate on the Paralympic level.
[10] At the 1992 Summer Paralympics, two types of volleyball were played including sitting and amputee, with classification being run through ISOD.
This policy was put into place in 2014, with the goal of avoiding last minute changes in classes that would negatively impact athlete training preparations.
All competitors needed to be internationally classified with their classification status confirmed prior to the Games, with exceptions to this policy being dealt with on a case-by-case basis.
[13] Going forward, disability sport's major classification body, the International Paralympic Committee, is working on improving classification to be more of an evidence-based system as opposed to a performance-based system so as not to punish elite athletes whose performance makes them appear in a higher class alongside competitors who train less.
