Exam system · Thai national ladder
Four rounds, one account, and a set of papers that decide in March what a student has been building since Matthayom 4.
TCAS is not an examination. It is the admission system that four different kinds of application pass through, and the papers sit inside it rather than above it. Round one takes a portfolio. Round two takes quota applications, which are regional and institutional rather than national. Round three is the central ranked round that most candidates think of as TCAS proper. Round four is direct admission, run by the faculties that still have places. A student can appear in more than one round, and the rounds close in order, so a place accepted early removes the later ones.
The current cycle has moved the papers earlier and made most of them free. The general and aptitude papers now fall at the very end of January, the medical aptitude paper in February, and the subject papers in the middle of March, all delivered on paper after a period of digital sittings. The general and aptitude papers carry no fee, subject papers are free for up to seven, and the first seven ranked choices in round three cost nothing. Candidates registered with the education equality fund receive a discount on the portfolio round's fee.
What is still charged is worth understanding, because it is also the strategy. Round three is priced per ranked choice, starting at 150 baht for a single choice and reaching 900 baht only if all ten are used. The fee ladder and the ranking decision are therefore the same decision, and a candidate who ranks ten programmes without a reason for each of them has paid to broaden a list they cannot actually prepare for.
From 15 August 2569 (2026)
Round one, portfolio. It opens before any paper is sat, which is why a portfolio has to exist before the final year begins.
30 January – 1 February 2570 (2027)
The general aptitude papers and the faculty aptitude papers two to five, on paper.
13 February 2570 (2027)
The medical aptitude paper, on its own date because it belongs to the medical faculties' consortium rather than to ทปอ.
13–15 March 2570 (2027)
The subject papers, registered for between 14 and 20 January. Rounds two, three and four follow from March through to mid-June.
Families read the four rounds as four chances at the same thing. They are four different applications with different evidence: a portfolio built over years, a quota claim based on where a student lives or studies, a national ranked list scored from the papers, and a faculty's own direct call. Preparing for round three and hoping the others will catch a fall is how a strong candidate ends up with one route instead of three.
The general papers, the faculty aptitude papers and the coded subject papers are prepared separately, because they are written by different bodies and test different things.

Yes, and it is time rather than money. Every paper has to be prepared to a standard, and preparation taken from a paper that counts to one that does not is the most expensive thing in the calendar. Free changes the cost of entering; it does not change the cost of being ready.
As many as the student would genuinely accept, which is usually fewer than ten. Ranking is priced per choice from 150 baht upward, so an unconsidered long list costs money and, more importantly, hides the fact that no real preference order has been worked out.
It needs guidance rather than production. The system now carries a shared portfolio standard and a verification step designed to keep out work the candidate did not do, so the useful help is the kind that makes a student's own work legible and honest, not the kind that supplies it.
Every external figure on this page carries its source. Edulom has not yet taught a student in Thailand, so there are no figures here about us.
TCAS runs four rounds: Portfolio, Quota, Admission and Direct Admission, administered by ทปอ.
