Back in 2010, I registered myself with the Singapore Sports Council's National Registry of Coaches (NROC). Unfortunately, I got busy with my job and let the membership expire in 2013.
Thankfully, I managed to clock enough coaching practice and coaching education hours to get a renewal.
And.. here it is! Had to clock an extra 20+ hours to get the renewal approved.
This system is similar to some industries. I believe the medical practitioners and registered safety officers have a similar system too, albeit a little more regulated.
