Parent-teachers are free to select the curriculum they feel will best meet the needs of their students. Your curriculum must be appropriate for the grade level declared.
Not all publishers present material in the same manner, nor do they cover concepts in the same order. Some courses, like high school biology, are clearly defined, while fourth grade history varies from “World Geography” in one publisher, with others covering “Civics” or “Florida History,” and still others are doing “Early American History,” and maybe even “The War Years,” or “World History from Creation to the Roman Empire.”
Many courses advertised heavily in the homeschool marketplace are not complete courses and are, in reality, more of a supplement designed for students in a class who need extra help. These should be used as such, and never treated as a complete course.
The list below is not an exhaustive list of publishers, just those that have been reviewed and approved for our students.
