Overview

About Lertlah School Petkasem Campus

The Petkasem campus is part of Lertlah’s three-campus private-school group in Bangkok. Its English Program combines the Thai curriculum with Canadian-inspired approaches, using English and Thai across academic subjects while retaining Thai language and cultural learning. Families can arrange a campus visit on 02 809 9081 or contact lertlahphetkasem@gmail.com. The current school website lists 1 Soi Petkasem 77, Lane 2-5, in Nong Khang Phlu, Nong Khaem. The captured map uses the older address 45 Moo 8 on the same soi; confirm the entrance and postal number with the campus before visiting.

International Program

The official group website identifies Petkasem as offering an International Program alongside its English Program. Ask Admissions which pathway and year group currently has places.
