The student should ask the ATO who conducted the training. Do they have an approval to conduct the BIFM Course? It is probable that they do not.
When the student starts the IR Course Appendix 9 to Part FCL states:
(a) Basic Instrument Flight Module
This comprises 10 hours of instrument time under instruction, of which up to 5 hours can be
instrument ground time in a BITD, FNPT I or II, or an FFS. Upon completion of the Basic Instrument
Flight Module, the candidate shall be issued a Course Completion Certificate.
So the crux of the matter is that the student must have a CCC to gain the credit.
The next option is to train for the CBM IR where the 10 hours training would be creditable and taken into account by the ATO assessing the training requirement.
