The CSAB Round 1 opening and closing ranks 2026 help students understand the rank range at which seats were allotted in NITs, IIITs, IIEST and other Government Funded Technical Institutes during Special Round 1. CSAB Special Rounds are conducted after JoSAA to fill vacant seats in the NIT+ System. In 2026, CSAB Special and DASA are being conducted under a common process with two seat-allocation rounds, although their seat pools and eligibility rules remain different.
The 2026 opening and closing rank data also include DASA-CIWG and DASA-Non CIWG entries. Students checking regular CSAB cutoffs should use only the Home State, Other State or All India rows applicable to them and should not mix them with DASA rows.
CSAB Round 1 Opening and Closing Ranks 2026
The opening rank is the best, or smallest numerical, All India CRL among the candidates included in a particular allotment combination. The closing rank is the last, or largest numerical, CRL in the same combination. The official CSAB OR-CR portal states that all ranks are All India CRL ranks and that the table covers fresh allottees and candidates whose seats were upgraded.
| Field | What it means |
|---|---|
| Opening Rank | Smallest numerical CRL allotted in that row |
| Closing Rank | Largest numerical CRL allotted in that row |
| Quota | Home State, Other State, All India or a separate DASA quota |
| Seat Type | OPEN, EWS, OBC-NCL, SC, ST or the relevant PwD seat type |
| Gender | Gender-Neutral or Female-only, including supernumerary seats |
A larger closing-rank number does not mean a better rank. For example, a closing rank of 30,000 is less competitive than a closing rank of 10,000. Students must also remember that an OBC-NCL, EWS, SC or ST row still displays the candidate's All India CRL, not the category rank.
CSAB Cutoff 2026 (Special Round 1)
The CSAB cutoff 2026 changes for every institute, programme, quota, seat type and gender pool. Therefore, one single cutoff cannot represent an entire college. The following entries are selected examples from the official Round 1 cutoff data. All rows shown below are for OPEN, Gender-Neutral seats and exclude DASA quotas.
| Institute and programme | Quota | Opening rank | Closing rank |
| NIT Tiruchirappalli - Computer Science and Engineering | Other State | 1,397 | 1,471 |
| NIT Rourkela - Computer Science and Engineering | Other State | 2,181 | 4,508 |
| NIT Warangal - Computer Science and Engineering | Other State | 2,335 | 3,119 |
| NIT Calicut - Computer Science and Engineering | Other State | 5,854 | 6,999 |
| IIIT Allahabad - Information Technology | All India | 5,423 | 6,391 |
| Dr. B. R. Ambedkar NIT Jalandhar - Computer Science and Engineering | Other State | 13,081 | 15,784 |
| Central University of Jammu - Electronics and Communication Engineering | All India | 108,937 | 245,924 |
These examples show why students should not judge CSAB only through top-NIT CSE cutoffs. Depending on the institute and branch, Round 1 closing ranks extend across a very wide range. If the opening and closing ranks are identical, it usually means that only one included candidate, or candidates with the same CRL, determined that row's rank range.

How to Check College-Wise CSAB Opening and Closing Ranks
Students can check the complete college-wise CSAB opening and closing ranks through the official website:
- Visit csab.nic.in.
- Open the DASA and CSAB-Special section.
- Click CSAB Special Opening and Closing Ranks 2026.
- Select Special Round 1.
- Choose the institute type, institute name and academic programme.
- Submit the filters and check the quota, seat type, gender, opening rank and closing rank in the result.
Always match all five factors before using a cutoff: institute, programme, quota, seat type and gender. For an NIT, a Home State cutoff should not be compared with an Other State cutoff. For an IIIT or another institute using All India quota, check the All India row. Similarly, a Female-only or PwD cutoff is not applicable to the general Gender-Neutral pool.

CSAB vs JoSAA Cutoffs: Which Ranks Are Higher or Lower?
CSAB closing ranks often reach larger numerical values than JoSAA closing ranks because CSAB fills vacancies left after JoSAA. However, this is a common trend, not a rule. Popular branches may have very few vacancies, and a CSAB row may be based on only one or two fresh or upgraded candidates. As a result, its cutoff can remain close to the JoSAA cutoff or even show a smaller numerical rank.
| Point of comparison | JoSAA | CSAB Special Rounds |
| Main purpose | Regular allocation, including NIT+ seats, through JoSAA rounds | Filling seats vacant after JoSAA and consequential vacancies |
| Seat availability | Wider seat pool at the start of counselling | Vacancy-based and usually smaller |
| Cutoff behaviour | Generally more stable across several rounds | More volatile because some combinations have very few seats |
| Choice process | Choices submitted in JoSAA | Fresh registration and choice filling are required for CSAB |
| Correct comparison | Match institute, branch, quota, seat type and gender | Use the identical combination before comparing |
Therefore, saying that the CSAB cutoff is always higher or always lower is incorrect. In rank language, a higher numerical closing rank usually means the seat was available at a less competitive rank. Students should compare the 2026 CSAB Round 1 data with the final JoSAA 2026 cutoff only after matching every filter.
What to Expect From CSAB Round 2
CSAB Round 2 will depend on the seats available after Round 1 willingness, reporting, upgrades and cancellations. The official CSAB 2026 schedule places the DASA and CSAB Special Round 2 result on 12 August 2026 at 5:00 PM IST.
Students may see three broad outcomes:
- The closing rank may move to a larger number where seats remain available and candidates with later ranks receive allotments.
- The cutoff may change only slightly when very few seats are available.
- A programme-category combination may show no meaningful movement if no new or upgraded allotment occurs in Round 2.
Round 1 closing ranks are useful reference points, but they are not guarantees for Round 2. The movement depends on actual vacancies, candidates' locked preference order, rank, quota, seat type and gender pool. A candidate near the Round 1 closing rank may have a possibility, but no fixed rank gap can guarantee an allotment. The safest approach is to use the exact Round 1 row relevant to the candidate and wait for the official Round 2 allotment and updated opening-closing ranks.
CSAB Round 1 Opening and Closing Ranks 2026: Conclusion
The CSAB Round 1 opening and closing ranks 2026 help candidates understand the institute-wise and programme-wise rank ranges recorded during Special Round 1. Students must check the exact combination of college, branch, quota, seat type and gender before comparing their rank with the CSAB cutoff 2026. DASA quota rows should be considered separately from regular CSAB allotment rows.
Candidates can use the CSAB Special Round 1 cutoff as a reference while estimating their Round 2 possibilities, but it should not be treated as a guaranteed prediction. Actual movement will depend on vacancies created after Round 1, candidate willingness, upgrades and cancellations. Students should wait for the official Round 2 result and updated opening and closing ranks before making a final assessment.
