Before leaving for Chompovon Primary School on the outskirts of the capital, students say, their parents give them 10 to 15 cents of pocket money. That's enough to buy some breakfast cakes and rice -- and pay their teachers a few cents before they walk into class.
The fee, a widespread practice in Cambodia's public schools, is a kind of informal toll that students must pay. If they don't, parents say, they risk receiving a lower grade or even being demoted.
Here, schoolchildren are taught at an early age what it takes to get ahead. And it only gets worse as they grow up. At every turn, Cambodians pay under the table: for a birth certificate, a travel visa, a fair ruling from a judge.
Transparency International, a corruption-fighting organization based in Berlin, says the majority of Cambodia's public servants earn their living by collecting bribes.
