## About

Lertlah School is an English Program private school under Thailand's
Office of Private Education Commission. The school's English Program
is accredited by the Ministry of Education of Canada and recognized
by the Thai Ministry of Education as a protocol English Program
school — meaning other private schools observe Lertlah's curriculum
as a model. The school uses an immersion methodology where students
learn English naturally throughout the school day via international
teachers from English-speaking countries, anchored in a Thai cultural
environment and traditions.

The school's motto, "เลิศล้ำคุณธรรม เลิศหล้าวิชาการ" (Morals and
Academic Excellence), reflects a commitment to both character
development and academic rigor across three decades of operation.
