Our Curriculum

Courses Specifically Designed for High School Students

SF Flex uses the K¹² high school curriculum which blends the best features of the company's patented learning environment—the elegant and research-driven design, the compelling interactivity, the ease of use of both online and offline content—with key features designed to make the high school experience successful, given the more complex content, skills, and time management requirements of high school students.

A Robust Catalog of Courses Meets the Needs of Diverse Learners

The K¹² High School Course Catalog is robust, offering an extensive portfolio of core and elective courses. K¹² Math, English, Science, and History courses are offered in multiple versions to meet the needs of diverse learners with diverse goals. Up to four levels of five World Languages (Spanish, French, German, Latin, and Chinese) are offered as well. Students can chart their own course, choosing from among the four levels of courses to match their aptitude and goals.

Four Versions of Core Subjects

With the K¹² high school curriculum, students can harness the power of individualized learning by choosing from the following four versions of Math, English, Science, and History courses:

  • K¹² Core courses are similar to the standard courses offered by many other programs. They meet all academic requirements for each course area both for graduation as well as for potential admission into a wide range of colleges.
  • K¹² Comprehensive courses are designed for students entering with a strong foundational knowledge and aptitude in the subject area being covered, as well as solid study skills.
  • K¹² Honors courses hold students to a greater degree of accountability, and demand even greater independence and self-discipline than their Comprehensive counterparts.
  • K¹² Advanced Placement (AP®) courses are college-level courses that follow curriculum specified by the College Board. Like K¹² Honors courses, AP courses require a greater degree of self-discipline for in-depth study of the subject.
