Hi Junwen. You need to add each relevant employer and role into the PER recording tool, along with details of your supervisor for each role. You also need to get each period signed off by the appropriate supervisor.
Periods when you were not working due to ill health, or extended periods of absence from work on sick leave, do not count towards the 36 months - nor do short periods of employment i.e. less than one month.
You may benefit from joining our webinar next week in which the ACCA team will share information on PER and you'll have a chance to ask them questions. Click here to register.
Hope this helps :)
