It so happen in touch with the officials and just got the latest stat for ISSEP in APAC, we only have 9 members hold ISSEP Concentration. (1 Vietnam, 1 Japan, 1 Pakistan, 1 Taiwan, 2 Australia and 3 Singapore).
Since Jan 2021, both Vietnam and Japan has 1 newly certified ISSEP.
We'll be updating the counts on our website again in a few months. We update with the January 1 numbers and then the July 1 numbers. I hope this helps!
