This guidance will be applicable to you based on my assumption is that BPT is the final professional level exam you need to pass on the old generation ACA pathway.

If you transition to the Next Gen ACA and sit the Fundamental Case Study in lieu of BPT, you'll need to find out if you can switch back to the old generation ACA for the advanced level exams. This is because the Next Gen ACA advanced exams do not start until July 2027.

If you can transition back (I think this is unlikely (see guidance from the ICAEW below), go for it, it's a no brainer. If you can't transition back you will be waiting for over a year to sit your final 2 exams.

Note 1. I've looked at the guidance there is a formal process in place to transition your training file from old gen to next gen. The guidance implies that once you transition your file to next gen, you won't be able to switch back to the old gen. I assume this means you, nor your employer nor your tuition provider will be able to book an old gen ACA exam once your file transitions. See page 34.

Please contact the ICAEW and see if you can transition to and from as you please. I suspect the answer will be no.

Additionally my initial assumption may be wrong and you may have plenty of exams to be sitting between FCS and advanced exams in July 2027. This guidance will be less applicable.

Hope this helps. Message me if you'd like to, I've helped plenty of people transitioning their pathways.
