The International School of Kuala Lumpur

Established in 1965 as Malaysia's first accredited international school, ISKL has grown from 48 students to over 1,800 representing more than 60 nationalities. Under General Principal Rami Madani's leadership, the school operates from a purpose-built campus in Ampang Hilir that opened in 2018, offering American curriculum with Advanced Placement courses alongside IB programmes. The school maintains triple accreditation through WASC, CIS, and IB organizations, with English as the strict medium of instruction and emphasis on six School-Wide Learning Results that guide assessment from elementary through high school.

Teacher discussions consistently position ISKL as KL's only true tier-one institution, with multiple educators describing it as their dream school and praising the supportive administration, competitive salary packages, and strong staff cohesion. Parents note the school's selective admissions process and non-profit status, which reinvests funds into facilities and programming rather than shareholder profits. The school offers extensive extracurricular programming including 11 varsity sports, 45 clubs, and international exchange opportunities, though some parents describe students as coming from very privileged backgrounds given the high fee structure.
