success/completion criteria help

In SCORM 1.2 there was only one variable that tracked both completion and success.  It was a shortsighted mistake that got corrected with SCORM 2004 which had separate variables to track each thing.

If you want more flexibility, and your LMS supports SCORM 2004, then I recommend you use that instead.

With regard to the Slide Views issue, you are correct that if you select both boxes then the participant would need to meet both criteria (score a pass as well as visit all slides in the project).

You can have just one or the other by simply deselecting one of the checkboxes. But you need to decide which is more important in deciding whether or not the person should be awarded credidt.

Personally, with SCORM 1.2's limitations, I have always felt that if you were choosing to talk about someone passing or failing the module, then it was implying they had to achieve a passing score.  So using the Quiz is Passed option made more sense.  If it was only really necessary for the person to get all the way to the end of the module, and quiz questions or scores were not that important, then using Slide Views made sense.

However, you need to be careful about using 100% Slide Views as if there is any chance that the learner can jump over or miss any slides, then they will not be awarded credit.  So, using Slide Views with a Branching Story module can be problematic unless you also have use of a method of artificially marking certain slides as completed even though not visited.  (The CpExtra HTML5 widget for Captivate is one way to achieve that.  Details here...)
