Do all Courses gain the client a Qualification? If not you'll want to have a way in the Course table to flag the ones that do.
Basically what you're looking for to run that tab is a Totals Query, I believe. You want the latest (Max(DateAchieved) version of any qualifying class, the Employee information (name and/or ID, your choice), and the course name and level. because it's a Totals Query it will be read-only so your header will need to be updated, but all the information can be input on the Courses tab, looks like.
