@tesu to be honest, I’m not actually sure how an individual would make reference to CEP if they don’t have access to it. As an agent myself, since I’ve got the subscription to CEP, I could make reference to it when I write a cover letter for my client.
You’d probably just have to check which section you fall under. Not sure how others here in the forum do it so you might want to ask those DIY applicants. From there, you can just claim points and the case officer will just verify if you claimed the right points for your qualification using their access to CEP as well. Good luck.
