Reporting is a combination of things. some are articulate settings. Some are Moodle settings.
Is activity completion turned on for the activity? If so, is it set to report on completion of specific things (dotted line box) or is it set to report complete when the participant checks the box (solid box)? The activity settings offer several options...completion on passed or completed, completed on a specific grade, etc. I tend to not use passed/completed (completed/passed doesn't seem to be consistent to me--which may be my modules and may be Moodle...) and I use a grade requirement instead.
What are your articulate settings? Several previous posts have looked at the reporting settings--you might look and see what yours look like compared to others who use articulate. And you might check the articulate community boards (which are almost as awesome as Moodle boards)--because they frequently have great solutions if the problem happens to be the SCORM, not Moodle. Also, they have lots of tutorials. (I don't actually use Articulate, but I know a little about it because Tom Kuhlman is my hero...)
