Hi Bhavesh!!! For taking the IELTS, your minimum age should be at least 16 years & you must have a valid passport and you will be eligible to take the exam if you fall into one of the categories:

• Planning to study in UK/Australia/Canada/New Zealand/USA
• Being a medical professional, planning to work or study further in UK/Australia/USA
• Planning to emigrate to Canada/Australia/New Zealand.

Hope that helped.Thank you
