Is there a national ranking of homeschool curriculums or curricula?

No. There is no national ranking of homeschool curriculums or curricula. Instead, parents are free to choose any curriculum that they believe is best for their child. There are many different types of homeschool curriculums available, from secular to religious, from traditional to alternative, and from free to expensive. Parents should research the different curriculums available and choose the one that is most suitable for their child's individual needs and learning style.
