Vet that charity is an archives tag for lorenweisman.com that asks for people to consider to look deeper into the validity of a non profit or charity.
As you vet, it is not about finding a charity that gives 100%. They are few and far between. Any charity will need operational flow and they do report it. I prefer charities that have operational costs of at most 35% and down. Those that have higher budgets seem a little suspect to me.
In the end,
Look before you leap and give. Make sure that you are helping the charity or the people you want to help. Take those extra moments to ensure your donation is going where it is supposed to go and to those you want it to go to.
