According to the Foreign Service Institute, English speakers need approximately 1100 hours of study over 44 weeks to reach Professional Working Proficiency in Bengali (ILR Speaking-3 / Reading-3). These figures represent full-time classroom instruction with professional guidance and immersion.
Bengali belongs to the Indo-Aryan branch of Indo-European languages, which provides some linguistic advantages for English speakers despite the significant structural differences. However, the Bengali-Assamese writing system presents a notable hurdle for learners accustomed to the Latin alphabet. Actual learning timelines vary considerably depending on study intensity, prior language experience, and personal aptitude. Casual self-study pursued part-time typically extends the timeline substantially beyond the FSI estimate.
What makes Bengali easier or harder
FSI difficulty tracks how far a language sits from English. Bengali is in the Category III tier, written in the Bengali-Assamese script, from the Indo-European (Indo-Aryan) family. A closer family and a familiar script generally mean fewer hours; a different script or grammar adds time.
