I am not sure if other NGOs try to rate them. It is a good and fair concept to rate NGOs
2. On what different criteria should / can NGOs / nonprofits / charities / trusts be rated?
It should be , if at all, based on the achievemennts and results
3. Who should rate them? i.e. backgrounds of such organisations or individuals
It needs to be people from various sectors and their opinions
