Undergraduates, apprentices and trainees can become Associate Members, and qualification for MInstP is normally by completion of an undergraduate degree that is "recognised" by the institute &ndash; this covers almost all UK physics degrees.<ref name=register>{{cite web |url=https://www.iop.org/sites/default/files/2022-11/Register-of-accredited-courses-Issue-38-July-2022.pdf |title=Register of Accredited Courses |publisher=IOP |date=July 2022 |access-date=19 June 2023 |archive-date=19 June 2023 |archive-url=https://web.archive.org/web/20230619125937/https://www.iop.org/sites/default/files/2022-11/Register-of-accredited-courses-Issue-38-July-2022.pdf |url-status=live }}</ref> An MInstP can become an FInstP by making "an outstanding contribution to the profession" that is judged via double-blind and anonymous peer review.
