At S.C.A.O school a volunteer can really have an impact on the life of children from a poor community ! New ideas are welcomed by everyone and volunteers can take over responsibility if they want to. You will get a great insight into the daily struggles of an NGO trying to support education in a poor country like Cambodia and can try to solve them! Alone, you can't change the world, but at S.C.A.O you can at least change the world for a few children.
The volunteers can expect to be treated in a truly welcoming way. The whole community has an interest, that the volunteers are happy (as their children will get better education), so everyone treats the volunteers very well, help them with travel recommendations, organize TukTuk drivers etc.
