Overview
TCAS (Thai University Central Admission System) is the national process for entering Thai universities, run by the Council of University Presidents of Thailand (CUPT, ทปอ.). It is not one exam. It combines four admission rounds with shared national tests: TGAT (general aptitude), TPAT (professional and academic aptitude) and A-Level (subject knowledge). This page follows TCAS70, the cycle for the 2027 academic year (Thai year 2570).
Who can apply
Students who finished school abroad or hold a GED need equivalence documents through the CUPT equivalence system: a certificate of equivalent qualification and a GPAX equivalence certificate if complete, or a provisional certificate if their studies or GED exams are not finished. Each applicant can give up a confirmed seat only once in order to apply in a later round.
Exam pattern
The national tests listed in the TCAS70 blueprint are:
| Test | Subject |

Results for each round are published in the TCAS system on fixed dates, followed by a window to confirm the seat.
