High School Academics

Online High School Curriculum

Carolus Online Academy (COA) knows success is not a single destination, and the journey can take many turns. But no matter the path, we believe in unlocking every learner’s potential by meeting them where they are and helping them reach their goals.

As students move through middle school and into high school, their work becomes increasingly independent. High school courses are designed for students targeting a four-year university, a local community college, or an immediate career.

Many high school courses are offered at two levels: on-level and honors.

In all course levels, students:

  • Learn grade-level content
  • Complete coursework that might require writing or
    research projects
  • Tackle problems that require analytical thinking

In honors courses, students also:

  • Evaluate and synthesize information
  • Demonstrate more advanced writing skills
  • Participate in honors projects

Plus, we offer credit recovery courses, which are mastery-based and allow students to focus on the areas they need most to recover credits at an accelerated pace.


*The K12 high school catalog is a complete list of the high school courses K12 provides. While COA offers a comprehensive selection of courses, not every K12 high school course is available to COA students. Information on specific courses of study and available electives are provided upon enrollment. For details, please speak to an enrollment consultant during the enrollment process.
