ISC - Muscat offers its students an educational approach that maximizes the chances of success with emphasis on English, mathematics, science, and a second language.

• English is the medium of instruction.
• Mathematics is the prerequisite for the in-depth understanding of the natural sciences and related subjects.
• A second language is stressed throughout the curriculum. From KG1, parents may choose between Arabic and French, and they receive a minimum of one hour of instruction in their chosen language each day. From Grade 7 onwards, French as a third language is introduced.

Students who do not have the minimum basic knowledge of English and mathematics must possess the determination to make up for any deficiency through sustained hard work. Accelerated programs are available to help students reach the required standard as quickly as possible.
