High Quality Content by WIKIPEDIA articles! Para-nordic skiing classification is the classification system for para-nordic skiing which includes the biathlon and cross country events. The classifications for para-Pordic skiing mirrors the classifications for para-alpine skiing with some exceptions. A functional mobility and medical classification is in use, with skiers being divided into three groups: standing skiers, sit skiers and visually impaired skiers. International classification is governed by International Paralympic Committee, Nordic Skiing (IPC-NS). Other classification is handled by national bodies. Before the IPC-NS took over classification, a number of organizations handled classification based on the type of disability.
