Students as young as 6th grade may enroll in UTHS's online courses prior to entering high school if they meet the course prerequisites. To enroll in an introductory level 9th grade core course, students must successfully complete the corresponding core courses as a prerequisite or successfully pass the 8th credit by exam for that core subject with a score of 80% or higher. Please keep in mind that all high school course grades are recorded on the student's high school transcript.
