Source: CBSE, CTET September 2026 Information Bulletin, section on online uploading of scanned images (published May 2026). The Bulletin gives sizes in centimetres, not pixels. At 100 DPI, 3.5cm x 4.5cm is roughly 138 x 177 px; at 200 DPI it is about 276 x 354 px. Either works as long as the file lands in the KB range.
No other document upload is asked for at the application stage: the Bulletin lists only the photograph and the signature, plus the fee payment. Keep your eligibility documents, such as your D.El.Ed or B.Ed mark sheets, ready for later verification, but you do not scan them for this form.
CTET 2026 dates so far
This cycle has had more changes than usual, so here is the sequence from CBSE's own public notices:
- 8 May 2026: notice for the 22nd edition; applications open 11 May to 10 June 2026.
- 25 August 2026: after a Supreme Court review judgment on the TET requirement for teachers, CBSE reopened the portal from 25 August to 1 September 2026 for candidates who had missed the first window. Those who had already applied did not need to apply again.
- 7 September 2026: online correction window from 7 to 10 September 2026, open to both groups. No correction is allowed after 10 September.
- 14 September 2026: the exam will be held on 12 and 13 December 2026. City and date details come on the portal 15 days before the exam, and the admit card two days before.
The original date of 6 September 2026 no longer applies. If you applied in either window, your photo and signature from the application will appear on the admit card.
How to prepare the two files
- Take a recent, clear, front-facing photo against a plain light background. The Bulletin stresses a latest photo because it is matched with your face at the centre.
- Crop it to a 3.5:4.5 portrait shape (width to height), with your full face and top of the shoulders.
- Resize it to between 10KB and 100KB as a JPG with the photo resizer. Aim for 40-80KB so it is well inside the range.
- Sign on plain white paper with a dark ball point pen, in your usual running signature.
- Scan or photograph the signature, crop it to a wide 3.5:1.5 strip, and bring it to 3-30KB with the signature resizer. If your scan has a grey or shadowed background, see removing the background from a signature.
- Upload both on ctet.nic.in and check the preview before paying the fee.
The 3KB to 30KB signature range is much smaller than most bank or SSC exams, which usually ask for 10-20KB. A signature saved at 50KB for another form will be rejected here, so re-export it for CTET.
Fee and correction rules that affect your photo
The Bulletin fee is Rs 1,000 for one paper and Rs 1,200 for both papers for General and OBC (NCL) candidates, and Rs 500 and Rs 600 for SC, ST and differently abled candidates, with bank GST charged extra. Payment is online only, and the fee is not refunded.
Your particulars cannot be edited after the fee is paid, except during the correction window CBSE announces. For this cycle that window closed on 10 September 2026. If your e-admit card shows a wrong photo or signature compared with your confirmation page, the Bulletin tells you to contact the CTET Unit immediately.
If you are preparing for the next CTET
CBSE usually issues a new Information Bulletin for each edition. The photo and signature sizes above are from the September 2026 Bulletin; the next edition's Bulletin may keep them or change them, so check it when it comes out. Keeping a clean original photo and signature scan on your phone means you only need to resize them, not reshoot them. For other exams with different sizes, see reducing photo size in KB on a phone.
Common mistakes
- Uploading a signature above 30KB because it was saved for a different exam.
- Using a square selfie crop instead of the 3.5 x 4.5 portrait shape.
- Using an old photo that does not look like you on exam day, even though the Bulletin says it will be matched at the centre.
- Saving a PNG or screenshot and renaming it .jpg instead of exporting a real JPG.
- Assuming the September exam date still stands: the 22nd edition is now on 12 and 13 December 2026.
