I decided to go to Nicaragua because I wanted to do something after my studies.
After some researchers I found this program at La Esperanza Granada where you can become an an assistant for the teachers in the schools. You can participate to English classes, help at the kindergarden,... There is many ways you can help.
As student in communication, I worked at the office and I went to the computer classes 3 days/week.
This was really good to see both sides of the organisation : one more professional and one with the children.
