IISA offers courses that lead to students sitting examinations in the IGCSE and IB. It also offers courses for which students are not expected to sit for external examinations. All courses offered in the high school section of IISA offer credit that can be used towards graduation from the school with the IISA High School Diploma. To graduate with the IISA high school diploma the student must obtain a minimum of 25 credits, which must include the following:

English	4 credits	Mathematics	3 credits
Social Studies	3 credits	Science	3 credits
Languages	3 credits	Fine Arts	1 credit
Computer	1 credit	Physical Education	1 credit
Electives*	6 credits	Total	25 Credits

A student obtains a credit by receiving an end of year grade of 3 or better in a course that meets a minimum of 120 Carnegie Units per year. (Note: A grade of 2 can be accepted for credit if recommended by a faculty committee and agreed to by the Head of School.)

Electives include any course offered at high school level that is graded on a scale 1-7.

In addition to satisfying the above criteria all students must complete:

• A total of 150 hours of CAS activities during grades 11 and 12.
• A research paper (following the same guidelines as the IB extended essay). This will be graded on a pass/fail basis. The essay must contain correct footnoting, citations, endnotes, bibliography and multiple researched and used sources. The length of the essay must be more that 2500 words and no longer than 3000 words.

Results in external examinations such as IB, PSAT, SAT, ACT and TOEFL have no impact on IISA school grades or IISA High School Diploma credits. However, a student taking an IB or IGCSE course has the opportunity to obtain a grade that counts towards the IISA High School Diploma and to sit the external examination that will result in the student receiving an IB or IGCSE certificate. (Note: There are special considerations concerning IGCSE exam grades. These deal with the ability to enroll as an IB diploma candidate.) IISA uses these results as prerequisites to enter certain IB courses.
