For CompTIA exams, they usually run on a three-year cycle which means that every three years the next version comes out. The exact date is usually announced about three months prior to the new exam coming out.



For ITIL and Prince2, they operate on longer cycles. The current version of ITIL (ITIL 4 and the associated exams) were first introduced in 2018 and are not expected to be replaced for several years. The current version of Prince2 and Prince2 Agile exams came out in 2017 with the last version of the exam having been released in 2019. We do not expect Prince2 to be replaced any time soon.
