Question: What is a pid?
Answer: Many schools use different titles to identify or label a group of candidates or a program; such as Class of 2018 graduates or Executive MBA's of 2020.
Because there are many different variations of titles for candidate groups or programs, we use the term PID as a general means of identification. Therefore, we might refer to the programs mentioned above as the 2018 2nd year PID or EMBA 2020 PID.
