StillJulie,
The "Introduction" in each of our guides goes through each box of plans in the guide and each subject area and gives an explanation of how it is handled and taught in the HOD guide. This is typically what is handed in to the state if needed for verification of what is being taught. Many, many families just print this out from our website and turn it in for reporting purposes. Each "Introduction" varies from 12-23 pages and really gives a great look at the various subject areas.
If further detail is needed, then you need to go to the Table of Contents of the various parts of the program to get a more in-depth view. For example, the Table of Contents in grammar and math are very helpful for more specific skills. The same is true for the opening pages of the DITHR guide (as well as the cover sheet that begins each genre) and for each of the writing programs scheduled in our guides.
For history, we always have spine books that have good Table of Contents for the topic coverage. The same is true for the science resources. Poetry is contained in the Appendix. Bible is explained in the Introduction and in the upper guides includes a separate Bible Student Book with its own Introduction and scope.

Courses like composer study and nature study also have good overviews in their Table of Contents.
It's good to remember that the HOD guides are meant to guide you through the curriculum, and function like lesson plans, however they are not the curriculum. The curriculum is made-up of the books that are used with the lesson plans (or with the guide). That is why you need to go to the specific books to gain the scope of the materials used within the curriculum.

This is true for all curriculums.
For example, during my public school teaching days, I was required to write lesson plans and turn them in each week. The plans did not ever include a scope and sequence but rather were required to include page numbers, procedures, questions or a way to assess the kiddos, and some sort of a key idea or lesson focus. This is what is contained within our lesson plans (or Teacher's Guides).

The scope and sequence was instead contained in the individual pieces of the curriculum.
Blessings,
