Most new government school teachers in Sri Lanka come through the National Colleges of Education (NCoE). Students join after their A/Levels, complete a 3-year National Diploma in Teaching, and move into the government teaching service.
Places are limited and selection runs on strict rules. This guide explains those rules so you can check your eligibility before the next gazette appears. For a comparison with private and international school routes, read our guide on how to become a teacher in Sri Lanka.
What the NCoE course involves
The main programme is the 3-year pre-service National Diploma in Teaching (NDT). It’s run under the Ministry of Education, with curricula developed by the National Institute of Education (NIE). Students specialise in 1 subject area, such as primary education, science, mathematics, English, ICT, religion, aesthetic subjects or physical education.
There are colleges across the country, including Maharagama, Siyane, Hapitigama, Pasdunrata, Ruhuna, Nilwala, Sri Pada, Uva, Peradeniya, Mahaweli, Wayamba, Pulathisipura, Ruwanpura, Sariputta, Jaffna, Vavuniya, Batticaloa, Addalaichenai and Dharga Town. Each college teaches specific courses and mediums.
A separate National College of Education on Technology at Kuliyapitiya runs a 4-year English-medium Bachelor of Education degree in technology subjects. Its 2026 gazette called for 210 student teachers.
Who can apply
The rules below come from the gazette of 7 November 2025, which admitted 2 groups at once: students who sat A/Ls in 2023 and in 2024. Each new gazette can change the details, so always read the current notice before applying.
- Citizenship: Sri Lankan citizen.
- Age: 25 or under on 1 January of the intake year. The limit for clergy and religious applicants was 30.
- Marital status: unmarried.
- A/L year: you must have sat the A/L examination in the years named in the gazette.
- Health and character: good physical and mental health and good character.
Educational requirements
G.C.E. A/L
You need 3 passes in one sitting. The subjects must match the course you apply for. A science course expects science subjects, for example, and a commerce-based course expects commerce subjects. The gazette lists the accepted subjects for each course.
G.C.E. O/L
- 6 passes, including your medium language (Sinhala or Tamil) and Mathematics, with at least 3 credit passes.
- If you passed in 2 sittings, the first sitting must include 5 passes, including the medium language, and 3 credits.
- For English-medium courses, you need at least a credit pass in English Language or an ordinary pass in English Literature.
Some courses add their own rules. Aesthetic subjects and physical education include a practical test, and the 2025 notice set a minimum of 40 marks to qualify.
How to apply online
Applications are online only, through the Ministry of Education portal at ncoe.moe.gov.lk. The application window is short. In 2025 it ran for 3 weeks, from 7 to 28 November.
- Read the full gazette in your language. It lists every course, medium, college and subject requirement.
- Check your O/L and A/L results against the course you want.
- Keep your NIC, A/L index number and result sheets ready.
- Complete the online form and choose your courses carefully. You can’t change them after submitting.
- If you’re eligible under 2 A/L years, the 2025 notice asked for a separate application for each.
- Print or save the confirmation slip.
How students are selected
Shortlisting is done by computer, using district or national quotas depending on the course. For each course, about twice as many applicants as there are places are called for interview.
The interview stage includes document checks and, for some subjects, a practical test. Final selection uses your A/L Z-score, your grades and your interview or practical marks.
Your district matters. A Z-score that misses out in Colombo may be enough in a district with fewer applicants for the same course. Apply for the course you’re genuinely suited to, and check which colleges teach it in your medium.
Preparing for the interview
- Bring originals and copies of every certificate named in the gazette. Missing documents are a common reason for rejection.
- Be ready to explain why you want to teach and why you chose that subject.
- For aesthetic and physical education courses, practise the practical components well before the test date.
- Our guide to common interview questions covers the general questions panels ask.
If you don’t get a place
You still have routes into teaching. Graduates can join government schools through graduate teacher recruitment and train later through a Postgraduate Diploma in Education. Private and international schools recruit teachers directly, often with a degree and a teaching diploma.
If you’re 25 or close to it, check the age limit first. It’s the rule that most often closes this route. See our guide to jobs for A/L school leavers for work you can do while you wait for the next intake.
