     The pupils of the remote Beau-Roc primary school in Haiti are chanting.One of them plays a guitar

made from an empty oil tin.Their headmistress, Emile Jean-Noel, is one of the few women school

headteachers in the country.

     Today, over 70% of Haitian population live without proper food, water, schools, or housing. To

reduce the hunger that prevents learning and to encourage parents to send their children to school, meals

are provided by the World Food Programme.

     "We are so cut off that we have many difficulties," comments Emile, adding that finding chalk, school

books and other materials is practically impossible.Emile tries to encourage people around her to make use

of available resources.Her efforts are bearing fruit.One of her successes was convincing local women to

contribute to their children' s schooling and increase their income by selling embroidery( 刺绣) and other

handicrafts.

     Recent political instability has meant that the country has not invested (投资) in education for ten

years.Only 44% of children go to school and less than half of them finish primary school. Less than a

third of these children go on to secondary school.In rural areas it is not rare to find 17 and 18 year olds

in primary school- Beau-Roc has only 4 teachers for 260 pupils.Emile works constantly to improve her

pupils' environment.Under her direction, a local worker is now constructing a store house for the food

delivered regularly by the WFP.

      Not only is Emile' s salary small, but she receives it irregularly.For her, transport is a real headache.

She lives five kilometers away and has to take the tap tap, a privately-owned bus, costing more than she

can afford.

     "The decision to be a rural teacher in Haiti should not be taken lightly", Emile comments. "With all the

sacrifices and risks it requires, only those who are really cut out for teaching should do it." However,

Emile loves her job. "I always feel at home with the children and, because the parents understand what I'm

doing, I try to give my best."
