How does a student achieve the IB diploma at Central High School?
The IB Diploma Program requires that students be fully immersed in the IB curriculum and its courses. Students complete six IB subjects and all required coursework/examinations for those courses.

HL vs. SL
Three courses are to be taken at the “Higher Level” and three at are to be taken at the “Standard Level.”
 What is the difference between “high level” and “standard level”?
  •       It is NOT the quality of instruction, but the quantity of instructional time.
    • HL = 240 hours (i.e. a 2 year course)
    • SL = 150 hours (i.e. a 1 year course; however it can be offered over 2 years)
  • Differences also lie in the number of assessments per subject. 
The IB assessments in every subject are divided between internal assessments and external assessments.
  •       Internal Assessments = graded by the classroom teacher. Student samples are sent and moderated by an external examiner by IB
  •       External Assessments = all work sent to an IB examiner to grade. These exams are held in May of the senior year, except for IB Spanish/French, which is given at the end of the students’ junior year.
 Every IB subject is graded on a scale of 1 to 7. That score is a composite of various assessments.

Earning the IB Diploma:
 Subjects Taken (6) X Points Possible Per Subject (7) = 42 Subject Points
 "Bonus" Points:
In addition to the 42 subject area points, IB also provides a way to earn up to 3 additional points using a matrix consisting of a student’s grade in TOK (Theory of Knowledge) and the Extended Essay (EE) grade. A student needs to do well on both their TOK presentation/essay and on the Extended Essay.
How many points does the student need to earn an IB diploma?   24*From these 24 points…
  •       12 points must come from the HL courses (Biology, English, History)
  •       9 points must come from the SL courses (Mathematics, Foreign Language, 6th Subject)
  •       The student cannot earn a 1 in any course or a 2 in HL
  •       The Extended Essay must be completed
  •       All internal and external assessments must be completed
  •       All Creativity, Action, and Service hours completed (150 hours total, 50 for each category)

Every IB subject is graded on a scale of 1 to 7. That score is a composite of various assessments graded both inside (internal) and outside (external) the classroom.
