She doesn't think the scores tell the whole story: she says there are teachers who want to do better but haven't been taught properly.

The President has attempted to tackle the problem with efforts like the teachers' test. He says for teachers that aren't improving, the government will have to find a way to remove them from schools.

Now the Peruvian government is focused on improving teacher training. They feel that poor education is a hindrance to development.
