Pupils in Finland are thought to be among the brightest in Europe. They regularly score well in the OECD's PISA assessment tests. That's due in large part to their highly dedicated teachers. Finland has a bonus system that rewards educators who go the extra mile.Teachers earn bonuses for offering extra courses, doing environmental or violence prevention training, or offering additional assistance to disadvantaged children. The bonuses can add as much as a third to a teacher's basic salary. Both pupils and teachers benefit from the program, which also helps make teaching a more attractive profession.
