ICBA as a professional body closed in December 2021.
ICB is the examination body and does not operate as a professional body nor gives tuition support (related directly to subject matter).
The webinars are not curriculum material but information relevant and useful for the "world of finance" as it were, and ICB is offering this as a value add to their providers, students and public as a value add.
Added to that any webinars viewed you will receive 1 CPD point, a digital certificate and a digital badge for the material viewed.
