Society Membership Subscription Tiers

AOSR society membership fees vary by society size whilst corporate membership fees are on a case-by-case basis.

AOSR Society Membership Tiers

The annual membership fees are currently determined by the number of the registered members within each society. Society membership is stratified into tiers accordingly as shown as of Jan 1, 2025, after approval at the General Assembly in March 2024. The membership fees and tiers are reviewed and updated from time to time by the AOSR. (The previous membership tier was reviewed in 2013, and remained so until the end of 2014).
