Is it possible to run a report that would show: Curriculum title, Courses (contained in it), and Lessons (in those Courses)?
I don't know about lessons but there is the option to see courses in Curriculum
Under the course report there is a little toggle next to the top filter, if you click that it will give you the option
I agree that this should be available in the standard tabular reports. It is available in Analyze with one caveat; there is no way to see it all in one report as the data comes from two different sources. You can however, include two reports in the same dashboard; one for curriculums and one for courses.
The Curriculum Enrollments data source includes Curriculum and Course data.
The Course Enrollments data source includes Course and Lesson data.
This would be fantastic! This is definitely a key report that is missing.
