What are coaching requirements

hello
there are some clubs in my city which don't play table tennis, and i thought that i could teach kids how to play the game in one of the clubs because i love table tennis and i want to do something good for the society.
i trained my brother and some of his friends four hours a week for 2 months and i seen significant improvement in their playing, that what led me to look for this information but i couldn't find much of information, i will be grateful to you if u help me with your experience.
what are the requirements for table tennis coaching?
what is the way to get a certificate from ittf?
should i be present in the courses or there are online courses?

Thanks in advance

Hi Hassan,

Well done on wanting to do something for the community and in particular with Table Tennis.

The best thing is to contact your State or National Table Tennis Association.  Each country has their own requirements.

Pursue it, you will find it rewarding.
