Here's a common problem (and a solution)

You have to ensure that students meet all performance criteria to be assessed as competent, but it's often difficult to catch them all in a once-off or short-term assessment. Sometimes performance criteria miss out "if relevant" or "if required", so students must meet them. These performance criteria don't necessarily apply every time student performs the element.

It doesn't help that some performance criteria are poorly written, and sometimes don't even relate to the element.

What to do

In simpler cases, you can integrate them into the instructions for the assessment task. If the students do the task as described, they have met the requirements. In more difficult cases, the best way might be to give an on-job assessment over a longer period of time.

Either way, you can cover a wider variety of incidences and honestly report that all performance criteria have been met. In fact, it makes your assessment process very simple and in the end, your assessment outcome is more reliable.
