Grading & Ranking Philosophy

To earn an OMIS High School Diploma, students must complete rigorous credit requirements across Math, Science, Humanities, and the Arts.
● Grading Scale: We utilize a 4.0 (A,B,C,D,E,F (+/-) grading scale.
● Class Rank: OMIS does not rank its students. We believe that a student’s performance is best represented by their individual academic achievement and personal growth, rather than a comparative rank within a highly competitive cohort.

Global University Partnerships (MOUs)

To provide our students with the best possible opportunities, OMIS actively partners with higher education institutions worldwide. We have signed official Memorandums of Understanding (MOUs) with several prestigious universities, granting our students unique pathways, resources, and networking opportunities. We are continuously expanding our network, with more exciting university partnerships upcoming!
