You will need to contact your club secretary who will discuss your grade changes at club committee level. If your club committee approves your grading changes, they will propose your changes at a regional committee meeting.
Once the regional committee approves your grade changes, you can apply online at www.airc.ie/shop and select Change of Grade. You will have to return your current membership card to National Office too before an new card will be issued.
If the regional committee does not approve your grade changes, then you must remain at your current grades.
