Definitely an LMS function. In a SCORM you can make it so they view each page or complete something on a page before advancing.

You can lock in the navigation so they have to pass to access a continue button (forced pre-requisite) if you want to call it that

Setting up Prerequisites is done in the LMS, so Prime can be the function for that, but Captivate does not have the ability to determine nor limit a user access, it is simply an authoring tool. As stated above, you can manage what the student can see via a pre-course evaluation of some sort, that will allow them to skip some of the slides, but there is nothing in place in Captivate to limit access to certain courses to certain to students. Basically the LMS can be the determining factor in allowing a potential student to access the course or not.

Your LMS can be setup to determine if the student has completed the required Prerequisites or not and either allow access to the course or deny them access, often with a simple message like “Sorry, you cannot take this course until you have completed course “X”.”
