Yes you do need the verification of 10th and 12th for the DGCA to issue you an FRTOL .
For those you who are facing issues in getting 10th and 12th verification sent to your home ( for eg some CBSE offices will only send it to the DGCA )
Write a written request for the same . Make copy and get a received stamp on it when you submit the written request at your respective regional office .
In the written request ask them to send to the below mentioned address.
To
Director Training & Licensing,
For File Number 9999/2012 (eg )
Directorate General of Civil Aviation, Technical Centre,
Opp. Safdarjang Airport,
Aurbindo Marg, New Delhi 110003
By mentioning your file number this should ensure that the verification letter is put into your file at the DGCA .
Many times the verifications are sent but once it reaches the DGCA most of the time it wont be there in your file .
Alternatively if your board does not give it to you , you can also ask the flight school in India where you will be doing your recency to request it for you .
