Casual employees on Revenue site

Not even sure how to express this question properly but here goes....

How are casual employees - say students who worked occasional days for a given employer during the summer - treated on the Revenue site? A neighbour's son is applying for SUSI as was told to print off the date of termination of employment for the job he was doing in the summer. Apparently, this can be achieved using some facility on the Revenue site? (The employment in question is really ad-hoc......will there even be a formal date of termination?)

[Apologies - I know this question is poorly worded.....I'm hoping that someone who knows about these things will understand what I'm trying to ask and fill in the blanks for me!]

The same as any other employees. They can print their employment details off MyAccount or if they have access ROS.
BTW, Revenue feed this data into SUSI.

Ask him to log into Revenue, then myAccount. He will get his details there. If his ex employer still has him on their system he can go into Cease Job and put in the date he finished himself.
