Hi there.

Yes, you indeed can apply for CDS 1 OTA in 2023 considering your age. Here I am listing the eligibility criteria for CDS OTA.

• Must be at least 19 years old before taking the test and cannot be more than 25 years old while taking it.

  The candidate must be single, widower, or divorced and have not remarried.

  Tattoos are only permitted on the inside elbow to the wrist area, as well as the back of the palm. Any other tattoo will result in disqualification.

  A minimum height of 148 cm is required for women.
