The Foreign Service Institute estimates that English speakers need approximately 1100 hours of study over 44 weeks to reach Professional Working Proficiency in Khmer, defined as ILR Speaking-3 and Reading-3 levels. This estimate assumes full-time classroom instruction with qualified instructors.
Khmer presents moderate difficulty for English speakers due to its distance from the Indo-European language family—it belongs to the Austroasiatic family instead. However, learners benefit from Khmer's Brahmic writing system, which is more regular and learnable than many other scripts. These full-time estimates assume intensive classroom study; independent self-study typically requires substantially more time to achieve similar proficiency.
What makes Khmer easier or harder
FSI difficulty tracks how far a language sits from English. Khmer is in the Category III tier, written in the Khmer (Brahmic) script, from the Austroasiatic (Khmer) family. A closer family and a familiar script generally mean fewer hours; a different script or grammar adds time.
