Common Reasons for CTET Application Rejection

To ensure your CTET 2026 admit card is generated without issues, avoid these common mistakes:

Blurry Images: Ensure your face is clearly visible. If you resize a very small thumbnail, it will blur. Start with a high-quality original photo.
Incorrect Background: CBSE prefers a white background. Photos with dark or "scenery" backgrounds are often rejected.
Signature in All Caps: Do not sign your name in CAPITAL LETTERS. Use your running handwriting.
Wrong Format: The portal only accepts .jpg or .jpeg. If your photo is a .png, our tool will automatically convert it to JPG during the download.
