[1] A holder of this office was formerly known as an assembly member (AM; plural: AMs; Welsh: aelodau'r cynulliad; AC, plural: ACau), under the legislature's former name, the National Assembly for Wales, from its inception in 1999 until 2020 when it adopted its current names, Welsh Parliament, and Senedd Cymru, simply referred to as Senedd in both English and Welsh.

[2][3] Since 2011, members are elected for a five-year term of office under an additional member system, in which 40 MSs represent smaller geographical divisions known as "constituencies" and are elected by first-past-the-post voting, and 20 MSs represent five "electoral regions" using the D'Hondt method of proportional representation.

This additional member system produces a form of proportional representation for each region.

All MSs positions become simultaneously vacant for elections held on a five-year cycle.
