To maintain and further develop ISPO, active involvement from the pilot community is essential. Maritime pilot organizations that are ISPO certified are required to become members of the IUG.
ISPO is a standard for pilots, by pilots. Through IUG membership, organizations can contribute to the continuous improvement of the ISPO standard and have voting rights at the annual Meeting of Associates.
The IUG Board sets the annual membership fee. The fee is €45 per pilot in 2026 and will increase to €50 per pilot from 1 January 2027.
