CUET UG Normalisation: Raw Marks, Percentile and the NTA Score Explained

CUET (UG) runs each paper in several shifts with different question sets, so NTA does not rank anyone on raw marks. It converts them twice: first to a percentile within your shift, then — by matching percentiles across shifts — to a normalised NTA score back on the raw-mark scale. Universities receive that NTA score. This guide goes through the method in NTA’s own terms, what the 2025 and 2026 results show about it, and why the marks-vs-percentile tables circulating online cannot be right.

In words: your standing in your own shift is fixed first. Then NTA asks, “what raw score sat at this same percentile in every other shift of this subject?”, and averages those. If your shift’s paper was harder, the other shifts’ raw scores at your percentile are higher, and the average lifts you; if it was easier, the average pulls you down. That is the whole correction — there is no separate difficulty weighting.

Two things follow. First, a percentile of 100 is easy to reach and says little: every shift’s top scorer is 100, so the more shifts and papers, the more 100s. Second, the NTA score is what universities use — DU, for example, adds the NTA scores of the papers in an accepted combination for each programme — often four. A “percentile” quoted for a whole application has no NTA definition at all.

The point of the example is the direction of the correction, not its size. A candidate in a harder shift (where 180 was enough for the 95th percentile) ends up above their raw score; a candidate in an easier shift ends up below it. Two candidates with the same raw marks in different shifts can therefore receive different NTA scores, and two with different raw marks can receive the same one. That is intended — and it is why nobody outside NTA can convert a raw score into an NTA score in advance.

NTA keeps the underlying records for 90 days from the result, and grievances must be raised within 30 days of it, under Delhi jurisdiction. After that the NTA score is final for the year: the 2026 score was valid for admissions in 2026-27 only.

Environmental Science is the counter-example to every marks table online: its best 2026 candidate had an NTA score of 170, not 240, and was still 100 percentile in their shift. The General Aptitude Test topped out at 212.65. A table that maps “240–250” to 100 percentile ignores that the scale of each paper is set by who sat it.

The same logic applies to the five-paper totals NTA prints for its toppers list. The highest in 2026 was 1232.19 (1225.93 in 2025), and twentieth place was 1177.65 (1176.44 in 2025). Those are sums of NTA scores out of a theoretical 1250 — NTA uses them to rank a table of toppers, not to give anyone a percentile.

The provisional keys and each candidate’s recorded responses came out on 9 June 2026, with challenges open until 11 June at ₹200 per question, non-refundable. NTA does not tell candidates which challenges succeeded, and there is no re-evaluation or re-checking after the result. The drop from 28 dropped questions in 2025 to 8 in 2026 is the clearest sign that the 2026 papers were cleaner — and under the 2026 rule a dropped question gives +5 to everyone who appeared.
