OK,
I will Try and keep it as simple as possible. This is how I read the situation.
Driver CPC came into force 10th Sept 2009.
2 types of qualification. Initial and periodic.
Initial Driver CPC:
New entrants who want C1 and C (who do not already have C1) and want to drive professionally need to do initial Driver CPC, i.e. modules 1,2,3 and 4.
Once new entrants have passed C1 or C ( or who have C1 under grandfather rights) will then be subject to periodic training: 35 hours every 5 years.
Periodic Driver CPC is for those who already had C1, C and C+E on 10th Sept 2009. They must complete 35 hours every 5 years (by 10th Sept 2014)
Periodic also applies to those new entrants who have attained the initial Driver CPC C1 or C (or have C1 under grandfather rights but the 35 hours they must complete will not be 10th September 2014. it will be 5 years to the date after having passed module 4.
i.e. I am a new entrant and I don’t have C1 under grandfather right. I take my initial cat C along with initial driver CPC and complete module 4 (say) 10th December 2009. Then I must complete 35 hours periodic training by 10th December 2014.
What Jennie (I think) is trying to say here is that she already has cat (it really does not matter when she passed it, i.e. before or after 10th September 2009.)
The point is she has to do the 35 hours periodic. She wants to attend a cat C+E course and wants to get periodic Driver CPC hours at the same time.
This in principle is possible as long as two factors count.
1, the course is at least 7 hours in duration within 24 hours periodic
2, the course is JAUPT approved (that is down to the training company to get approval) and JAUPT to approve it.
If those 2 criteria are met then she could do C+E and periodic Driver CPC at the same time.
I hope this clarifies the situation
