We're focussing on grades 9, 10, 11, and 12.
The titles of the content standards are:
Grade 9 -- no standards, schools are supposed to offer electives
Grade 10 -- World History, Culture, and Geography: The Modern World
Grade 11 -- United States History and Geography: Continuity and Change in the Twentieth Century
Grade 12 -- Principles of American Democracy and Economics
I think it is pretty clear, and a conversation with LittleDan has further convinced me, that our expertise lies best in Grade 10 -- World History, Culture, and Geography: The Modern World.
Here's the link: http://www.cde.ca.gov/standards/history/grade10.html
and similar for Florida: http://www.firn.edu/doe/curriculum/crscode/basic612/912/ss912/2109310.pdf
although the actual "Instructional Materials Specifications" for Florida are apparently buried here: http://www.firn.edu/doe/instmat/pdf/social_studies.pdf (see page 189, which is Adobe page 198)
As you can see, these are detailed specifications, and we should probably be able to write to it with a fair degree of success.
A "ToDo" list on this would include making sure that this is the right document to work from, and also to look on the web to see if Texas standards can be found as well.
And any other states or countries that anyone has a particular interest in, of course.
(For example, are there published content standards for courses in Australia and Great Britain, etc.?)
