Appendix D: Course Placement and Sequences (https://www.cde.ca.gov/ci/ma/cf/documents/mathfw-appendixd.p...):

> The California Common Core State Standards for Mathematics (CA CCSSM) represent a tight progression of skills and knowledge that is inherently rigorous and designed to provide a strong foundation for success in the new, more advanced Algebra I and Mathematics I courses that are typically taken by most students in grade nine.

And:

> Prior to the development of the CA CCSSM, “Algebra I” was taught in grade eight to an increasing number of students. That same course name will be the default for grade nine, as most students who move forward will complete the CA CCSSM for grade eight—and the new version of Algebra I is more rigorous and more demanding than previous versions of Algebra I.

Page 833 shows a diagram that by default gets students only to Precalculus in 12th grade, passing through Algebra I or Math I in 9th.

If CA is right that the new Algebra I is more demanding than the old then this could just be a question of semantics and definitions (though with calculus not an option by default it's still pretty clear that they're not covering as much material by default), but Conrad definitely didn't invent the idea of Algebra I being moved to ninth grade.
