We haven't done SL7 or the upper levels yet, but we are doing SL6. In the Language Arts program, along with comprehension questions for the all the books, there is focus on literary analysis: imagery, characterization, dissecting poems, diagramming plot, symbolism, etc. Is that what you're talking about?
It is not laid out for you for all the books individually --- but those things are taught and often the student is asked to incorporate the skill in a writing assignment.
Check Sonlight's website and you can look at Instructor Guide Samples - I think you can view the "Schedule for Topics and Skills", which I think would help you see what I'm referring to.
Hope that helped!
