You should check the relevant documents (JAR-FCL, EU-OPS, FARs etc) about that stuff.
In the outfits i flew for so far we had to rotate through all ATA chapters within a 3 year period which meant we had to do different chapters every six months as one training session (LOFT) and one check session per 6 months was (still is) required. Ground training nowadays is an online CBT which ends with a questionnaire which in turn has to be passed, again around 3 ATA chapters every 6 months and some additional stuff (work safety rules, radiation, cold weather operation etc) in between.
The LOFT (day 1) usually has 2 LOFT scenarios, one for each crew member as PF and then some additional training, for example airwork, visual circuits, circling approaches, general hands on flying and sometimes some CAT III training. Flight preparation for the first LOFT scenario has to be done in full, including loadsheet and performance calculation based on information given during the briefing, usually done before we enter the simulator.
In the check session (day 2) we do have 2 shortish LOFT sessions, again one for each pilot and after that each pilot has to do the usual OEI stuff, V1 cut, OEI procedure, checklist work, pattern back for an approach, go-around at or below minimum, normal G/A procedure, pattern back and another approach. At least one non precision approach and one precision approach has to be covered in both scenarios, however we do not need to do the OEI-G/A and the following approach raw data anymore (our loss actually), the captain has to do at least one rejected take off. If we didn't cover the LVP stuff on day 1 we do it on day 2, on day 2 we usually train additionally stall recovery techniques, if there is still some time left at the end we do whatever exercise the trainees want.
The major points are indeed required by regulation, however i do not know exactly if european or local regulation in this case.
