Who can apply
You can apply if you
- hold one of the high school qualifications below
- have one English test result from the last 2 years that meets the minimum score
- have never confirmed your right to a place in the TCAS Clearing House system
You qualify with any one of these.
| Qualification | What you need |
|---|---|
| Thai high school (Mathayom 4 to 6) | A complete GPAX of at least 2.80 over 6 semesters, or an equivalent |
| GED diploma | At least 165 in each subject |
| GCE O Level, GCSE or IGCSE, with AS or A Level | At least grade C in five different subjects, plus AS at least grade A to E in five subjects, or GCE A Level at least grade A to E in three subjects |
| International Baccalaureate | At least 4 in five different subjects |
If your records are not on a 4.0 scale, for example from an international school or an overseas school, apply with the HSCES High School Equivalence Certificate and GPAX Equivalence Certificate. A GED is different. Apply with your GED diploma and your GED score report. The BIR programme does not accept the HSCES certificate for a GED in TCAS 3.
If your school cannot issue all 6 semesters of grades in time, read Common questions.
These are the minimum English scores. You need one test only.
| Test | Minimum score | Required for | Counts as your English test for |
|---|---|---|---|
| TOEFL | 500 on the paper test, or 61 on the iBT | None | |
| IELTS | 6.0 overall | None | |
| TU-GET | 500 on the paper test, or 74 on the computer test | None | |
| SAT Evidence-Based Reading and Writing | At least 50 percent |
