A fellow TSR member PM me for info on international foundations. We messaged briefly. I think some other TSRers may be interested so I share my very limited knowledge here. I have no connection with any education services provider.
International foundations, also called international pathways, are offered to non-UK students who do not meet uni entry requirements, maybe they missed the required grades or their home academic qualifications are not recognised by the uni. The courses aim at preparing, or "beefing up" students for uni studies.
Students apply to the institutes direct and choose a stream of study, e.g. business mamagement, healthcare, engineering and social sciences according to their desired degree orogrammes. Entry requirements are set by the institutes are often very lenient, e.g. satisfactory completion of secondary education, formal qualifications (e.g. GCSE and A-Levels) are not always required.
International foundations are often referred to as RQF Level 3 equivalent, but are not always well or widely recognised because the qualifications are awarded by the individual institutes. Say if a student completed the course satisfactorily (say 50% overall) but still failed to meet uni entry requirements (say 55%), very probably he might end up with nothing because the qualification may not be well recognised by employers. The Home Office's "level up" student visa policy requires the the qualification of the course of a student visa application must be higher than that of the previous student visa, so there is not possible to "repeat" an international foundation course. PSW (post study work) visa is for degree holders and is not available to international foundation graduates.
So international foundations are not shortcuts to uni. The institutes rarely publish the progression rates to unis, but I know the rates are not close to 100%.
International foundations may be categorised into 3 groups according to the institutes, (1) offered by uni, (2) offered by private education providers, (3) offered by private education providers in collaboration/cooperation with unis. I will share my views separately in later posts.
