Excelsior American School is an International School where the medium of instruction is English. The medium of English language is integrated across the curricula by each subject teacher, not only in language classes. Excelsior also recognizes that each individual student has different learning needs and a different learning style. In order to facilitate learning the curriculum in English and to develop proficiency in the language, an additional intensive English Language Support program is designed for students who do not have English as their first language. Upon enrolment at EAS, English language needs are identified and assessed by in-class, English language facilitators.  Based on this assessment, a modified timetable is designed for students who need additional intensive English Language Support to allow for additional English classes each week and provide personalized support for language development. Besides this, such students are also required to attend their mainstream Language classes along with other students in their peer group, which will also positively contribute to their language development.
