Thai Language Schools: How to Choose an Accredited School

The ED Visa Through Language Schools

One of the most popular long-term visa options for foreigners in Thailand is the Non-Immigrant ED (Education) visa obtained through enrollment at a Thai language school. This visa allows stays of up to 1 year (with extensions) and is renewable as long as you remain enrolled and meet attendance requirements. However, not all language schools are equal — choosing an unaccredited or poorly managed school can result in visa problems, financial loss, or even deportation.

Ministry of Education Accreditation

For a language school to sponsor ED visas, it must be accredited by the Ministry of Education (MOE) through the Office of the Private Education Commission (OPEC). Accreditation requirements include: registered as a private school under the Private School Act B.E. 2550 (2007), approved curriculum with defined learning objectives, qualified Thai language teachers (minimum bachelor's degree, TCFL or equivalent certification), proper facilities (classroom space, materials), and financial stability (insurance/bond deposit).

How to Verify Accreditation

(1) Ask the school for their MOE registration number (เลขที่ใบอนุญาต). (2) Check with the local Office of the Private Education Commission — every province has one. In Bangkok, contact OPEC at 02-282-1000. (3) Ask for a copy of their school license (ใบอนุญาตจัดตั้งโรงเรียน). (4) Verify the school can issue the specific documents needed for ED visa: acceptance letter (จดหมายตอบรับ), enrollment confirmation, and the documents required for visa extension at immigration.

Attendance Requirements

Immigration takes ED visa compliance seriously. Requirements: (1) Minimum attendance: you must attend at least 80% of scheduled classes. Schools report attendance to immigration. (2) Class schedule: most ED visa programs require 4-8 hours of classes per week (minimum). Some immigration offices require more. (3) Progress assessment: schools must conduct periodic assessments showing the student is making progress. Failing or not attending can result in visa extension denial. (4) 90-day reporting: you must complete the standard 90-day address report with immigration throughout your stay.

School Closure Risks

A significant risk with language school ED visas is school closures. When a school closes (due to financial problems, loss of accreditation, or regulatory action), students typically: lose remaining paid tuition (partial refunds may be possible but are not guaranteed), need to find a new school and transfer their visa within 15-30 days, or must leave Thailand and re-enter on a new visa. To minimize this risk: (1) Choose established schools that have operated for 5+ years, (2) Avoid schools offering suspiciously low prices (they may be cutting corners), (3) Pay tuition in shorter installments (quarterly rather than annually) to limit financial exposure, (4) Maintain relationships with alternative schools as backup.

Cost Comparison (2026)

Typical ED visa language school costs in Bangkok: Budget schools: THB 15,000-25,000 per year (4 hours/week). Risk: lower quality, higher closure risk. Mid-range schools: THB 30,000-50,000 per year (6-8 hours/week). Good balance of quality and price. Premium schools: THB 60,000-100,000 per year (8-12 hours/week). Best teaching quality, most stable. University programs: THB 40,000-80,000 per semester. Academic setting, structured curriculum, highly stable. Additional costs: ED visa application fee THB 2,000, visa extension every 90 days THB 1,900, textbooks THB 500-2,000.

Student Rights

Under the Private School Act and consumer protection law, students have the right to: (1) A refund of tuition for classes not yet delivered if the school closes or you withdraw with reasonable notice, (2) Quality instruction as described in the school's approved curriculum, (3) Safe facilities that meet MOE standards, (4) Non-discrimination (you cannot be denied enrollment based on nationality, age, or gender), (5) Privacy of academic records (PDPA applies), (6) Complaint to OPEC if the school fails to meet its obligations.

Recommended Due Diligence

Before enrolling: (1) Visit the school in person — inspect classrooms, meet teachers. (2) Ask for references from current or former students. (3) Check online reviews (Google, Facebook, ThaiVisa forum, Reddit r/Thailand). (4) Confirm the exact documents they provide for immigration (some schools provide inadequate paperwork). (5) Ask about their policy if you need to pause studies (travel, illness). (6) Clarify the refund policy in writing before paying. (7) Understand what happens if the school changes location — your visa extension may reference a specific address.

Alternatives to Language Schools

Other ED visa options: Thai universities (bachelor's, master's, certificate programs), Muay Thai schools (with MOE registration), cooking schools (accredited programs), and vocational training (registered with MOE). University programs generally offer the most stable ED visa platform but are more expensive and academically demanding.
