How to Apply for a School Licence in Thailand: Step‑by‑step Process, Documents & Timeline

Anyone planning to open a private school in Thailand must first understand how to apply for a school license in Thailand under the Private School Act B. E. 2550 (2007). The licensing authority is the Office of the Private Education Commission (OPEC), a body operating under the Ministry of Education that regulates the establishment, operation, and closure of private educational institutions throughout the country. The process applies equally to Thai nationals acting in their own name and to juristic persons, limited companies, foundations, or associations, that wish to operate a formal school, a language centre, or a vocational training institution.

In 2025–early 2026, OPEC and the Ministry of Education moved to standardise application forms, inspection checklists, and review windows, making the procedure more predictable but also more demanding on document formalities.

Overview of the School Licence Process and Who It Applies To

Under the Private School Act B.E. 2550, no person or entity may operate a private school in Thailand without a licence issued by OPEC. The Act divides private schools into two broad categories: formal schools (offering curricula that lead to recognised qualifications, primary, secondary, or international programmes) and non-formal schools (language centres, tutorial schools, and vocational training establishments). Each category has its own application track, documentary requirements, and inspection criteria, although the overarching procedural framework is shared.

The Ministry of Education school licence regime gives OPEC the power to receive applications, conduct site inspections, impose conditions, and, once satisfied, issue the licence and register the school. For formal schools, OPEC also coordinates with the Teachers’ Council of Thailand (Kurusapa / KSP) to ensure that teaching staff hold valid professional licences. For higher-education programmes, the Office of the Higher Education Commission has a separate mandate; this guide focuses on the OPEC-regulated primary, secondary, international, and non-formal school tracks.

Types of School Licences

The most common licence is the formal school licence, which authorises an institution to deliver a Ministry-approved curriculum and issue certificates recognised by the Thai education system. International schools operating under a foreign curriculum (British, American, IB) still require this licence but follow additional curriculum-approval steps with OPEC.

Non-formal school licences cover language centres, tutoring schools, and short-course vocational providers. These licences carry lighter premises requirements but impose the same core eligibility and document obligations. A separate category exists for special-purpose training centres operated by corporations for their own staff, which fall outside the OPEC mandate in most cases.

Eligibility for a School Licence and Prerequisites

Before assembling any paperwork, applicants must confirm they meet the school licence requirements Thailand imposes on both natural persons and juristic persons. The Private School Act B.E. 2550 sets out minimum qualifications for the licence holder and for the school’s director or principal. Foreign applicants face additional structural requirements that merit careful advance planning.

Eligibility Checklist for Natural Persons

• Thai nationality. The Private School Act requires that individual licence holders be Thai nationals of legal age.
• Minimum age. Applicants must be at least 20 years old.
• No disqualifying criminal record. No conviction for offences involving dishonesty, fraud, or moral turpitude, a criminal background check is mandatory.
• No bankruptcy. The applicant must not be an undischarged bankrupt.
• Educational qualifications. While the licence holder need not be a qualified teacher, the appointed director or principal must hold at least a bachelor’s degree and meet OPEC’s managerial competence standards.

Eligibility Checklist for Juristic Persons

• Registration in Thailand. The entity, limited company, foundation, or association, must be registered with the Department of Business Development (Ministry of Commerce) and have its registered office in Thailand.
• Company objectives. The memorandum of incorporation must include an explicit objective “to provide education” or equivalent language approved by OPEC.
• Thai majority shareholding. Industry observers note that OPEC typically expects Thai nationals to hold the majority of shares in the applicant company, consistent with general foreign business restrictions under the Foreign Business Act B.E. 2542. Foreign investors commonly structure their participation through a Thai-majority entity or through Board of Investment (BOI) promoted projects.
• Qualified director/principal. The school must appoint a director or principal who meets the nationality, age, educational, and character requirements under the Act.
• Suitable premises. The applicant must demonstrate access to land and buildings that comply with zoning, building-safety, and sanitation standards, discussed further under Step 1 below.

Foreign educators seeking to teach (rather than own) a school should note the separate foreigner teaching licence requirements administered by the Teachers’ Council of Thailand (KSP). KSP issues provisional (P), basic (B), and advanced (A) teaching licences, each with its own qualification and documentation pathway.

How to Apply for a School License in Thailand: Step‑by‑Step Procedure

The steps to get a teaching licence in Thailand, and, more broadly, to establish and licence a school, follow a sequential path from site preparation through to post-licence registration. The procedure below reflects the OPEC framework under the Private School Act B.E. 2550 and incorporates practical guidance aligned with the standardised review processes introduced in 2025–2026.

Step 1: Conduct Pre‑Application Checks and Confirm Site Readiness

Before any forms are filed, verify that the intended school premises satisfy local zoning regulations and hold a valid building permit, commonly referred to as AOR 6 (or its equivalent under local building-control ordinances). Contact the local municipality or district office to confirm that the site is zoned for educational use. Arrange a preliminary safety and sanitation inspection to identify any remedial works. If the building is leased, ensure the lease term meets OPEC’s minimum requirements and that the landlord consents to the educational use in writing. This step typically takes 2–6 weeks, depending on the condition of the premises and the responsiveness of the local authority.

Step 2: Establish the Legal Entity (If Applying as a Company)

If the applicant is a juristic person that has not yet been incorporated, register a Thai limited company with the Department of Business Development (DBD) under the Ministry of Commerce. The memorandum of incorporation must include an objective to “provide education” or similar language that OPEC will accept. Ensure the shareholder structure complies with foreign-ownership limits and that the initial registered capital is adequate for OPEC’s operational-funding assessment. Company registration generally takes 1–4 weeks, depending on whether a company-name reservation is needed and on the complexity of the shareholder structure.

Step 3: Appoint the Director or Principal and Prepare Employment Contracts

Under the Private School Act B.E. 2550, every school must have a named director or principal (ผู้อำนวยการ) who meets OPEC’s eligibility criteria, Thai nationality, minimum bachelor’s degree, no disqualifying criminal record. Prepare a formal letter of appointment and draft employment contracts for all initial teaching and administrative staff. Foreign teaching staff must hold work permits issued by the Ministry of Labour, and their teaching qualifications should be verified against KSP requirements well before the licence application is submitted. Allow 1–2 weeks for appointment formalities and contract preparation.

Step 4: Compile, Translate, and Legalise All Required Documents

Gather every document listed in the required-documents table below. Foreign-language documents must be translated into Thai by a certified translator, and the translations notarised. Because Thailand is not a party to the Hague Apostille Convention for domestic-acceptance purposes, foreign public documents (degree certificates, criminal-record checks) must be legalised through the issuing country’s Ministry of Foreign Affairs and subsequently authenticated by the Royal Thai Embassy or Consulate in that country. Early indications suggest that incomplete or improperly legalised documents are the single most common reason for OPEC query letters, so applicants should budget 2–6 weeks for this step and begin the process before all other documents are finalised.

Step 5: Submit the Application to OPEC or the Ministry of Education

File the completed application pack with the OPEC office that has jurisdiction over the school’s location. For schools in Bangkok, this is the central OPEC office; for schools in the provinces, file with the relevant Provincial Education Office. Attach the OPEC-prescribed application form (available on the OPEC website at opec.go.th), all supporting documents, and proof of payment of the administrative processing fee. OPEC has been progressively accepting digital submissions alongside paper filings, confirm the current accepted format with the receiving office. This is “Day 0” of the formal review period.

Step 6: Respond to OPEC Inspection and Documentary Queries

After filing, OPEC assigns an inspector team to review the application file and conduct a physical site inspection. The inspection covers building safety, classroom capacity, sanitation facilities, and accessibility. OPEC may issue a written query letter requesting additional documents, corrections, or site remediation. Respond promptly, delays in answering queries extend the review clock significantly. Each query-and-response cycle typically adds 1–4 weeks. The administrative review and inspection phase typically takes 60–90 days for a complete, well-prepared file.

Step 7: Receive the Licence, Register the School, and Meet Post‑Licence Obligations

Once OPEC is satisfied that all statutory and regulatory conditions are met, it issues the school licence and registers the institution. The licence is published in OPEC’s records and the school may commence operations. Post-licence obligations include: filing annual reports with OPEC, ensuring all teaching staff maintain valid KSP professional licences, notifying OPEC of any change in director, premises, or curriculum, and submitting to periodic compliance inspections. Licence issuance normally follows within 1–2 weeks of the approval decision.

School Licence Documents Needed: Required Documents and Information

The table below consolidates the principal documents OPEC requires for a school licence application. Applicants should treat this as a checklist and confirm the current form numbers and accepted formats directly with the relevant OPEC office, as minor updates to prescribed forms occur periodically.

For foreign-sourced documents, remember that Thailand does not accept apostille authentication for domestic regulatory purposes. All foreign public documents must be legalised through the originating country’s foreign ministry and then authenticated by the Royal Thai Embassy or Consulate in that jurisdiction. This legalisation chain adds time and cost, begin the process early.

School License Timeline Thailand: Key Deadlines and Realistic Estimates

The end-to-end school license timeline Thailand applicants should plan for depends heavily on document readiness and the complexity of the premises. A realistic range is:

• Best case (complete file, compliant premises): approximately 4–5 months from the start of document preparation to licence issuance.
• Typical case: 5–7 months, accounting for at least one round of OPEC queries.
• Worst case (significant remediation needed): 9–12 months or longer if premises must be modified or key documents re-issued.

Within the OPEC review phase, industry observers expect the regulator to adhere to a 60–90 day processing target for complete applications, consistent with the standardisation efforts introduced in 2025–2026. Applicants should note the following deadline triggers:

• Query response deadline. OPEC’s query letters typically specify a response window. Failure to respond within the stated period may result in the application being shelved or returned.
• Appeal window. If OPEC refuses the application, the applicant may file an administrative appeal. The appeal must be lodged within the time frame specified in the refusal notice, typically 30 days, and is heard by the relevant appeals body under the Administrative Procedure Act B.E. 2539.
• Engage counsel early. Given the document-intensive nature of the process and the consequences of missed deadlines, applicants are advised to engage a licensing specialist before filing.

Cost to Apply for a School License: Fees and Tax Considerations

The cost to apply for a school license in Thailand comprises government fees, professional-service fees, and ancillary expenses. Exact government fees vary by licence type, region, and the applicable ministerial regulation in force at the time of filing, applicants should verify current amounts directly with OPEC.

Schools operating as Thai limited companies are subject to corporate income tax and may be liable for VAT on certain non-educational services. Specific tax incentives may be available for BOI-promoted educational projects. Applicants should seek tax advice alongside the licensing process.

What Changed in 2025–2026 for School Licence Applications

In 2025 and early 2026, OPEC and the Ministry of Education introduced several procedural refinements aimed at making the school licence application process more transparent and predictable. The likely practical effect of these changes is threefold. First, OPEC has standardised its application forms and inspection checklists, reducing the ambiguity that previously led to inconsistent requirements across provincial offices. Second, the regulator has signalled a target review window of 60–90 days for complete applications, giving applicants a more reliable planning horizon. Third, document formalities have become stricter, OPEC now scrutinises legalisation chains for foreign documents more closely and expects all translations to be performed by certified translators.

For applicants, the practical advice is clear: use the latest prescribed forms available on opec.go.th, begin foreign-document legalisation well in advance, and ensure every document in the file is complete before submission. A complete initial submission dramatically reduces the likelihood of query letters and keeps the application within the standard review window.

Common Pitfalls and How to Avoid Them

• Incomplete application file. Missing even one document triggers a query letter and resets part of the review clock. Use the documents table above as a hard checklist, do not submit until every item is confirmed.
• Non-translated or improperly legalised foreign documents. Submitting uncertified translations or documents that lack consular authentication is the most frequent cause of rejection. Begin the legalisation process at least six weeks before the planned filing date.
• Company objectives mismatch. If the company’s memorandum of incorporation does not explicitly include “to provide education” (or substantially equivalent Thai‑language phrasing), OPEC will refuse the application. Amend the objectives with DBD before filing.
• Unsuitable premises. Buildings that lack a valid AOR 6 permit, fail fire-safety standards, or sit in a non-educational zone will not pass the OPEC site inspection. Conduct a pre-inspection audit before committing to a lease.
• Director or principal does not meet statutory requirements. The appointed director must satisfy the nationality, age, education, and character criteria under the Private School Act B.E. 2550. An appointment letter for an unqualified individual will be rejected.
• Missing teacher licences. All teaching staff at formal schools must hold valid KSP professional licences. Schools that submit staff lists without corresponding KSP licence numbers face inspection failures. Verify each teacher’s KSP status before filing.
• Late response to OPEC queries. Failing to reply within the specified deadline can result in the application being returned. Assign a dedicated compliance officer to monitor and respond to all OPEC correspondence.
• Insufficient lease term. OPEC requires the lease on school premises to run for a minimum period aligned with the school’s operational plan. A short-term lease will be flagged. Negotiate the lease term before signing.
• Inadequate proof of funding. Applicants who cannot demonstrate sufficient capital to sustain operations will not receive a licence. Prepare bank statements or audited accounts showing adequate reserves.
