what happens when a test company gets it wrong

[patrice]

Here in France, even if things evolve, they are a little different.
Schools are mainly government (Ministère de l'Education)
On the day by day basis, teachers are free to build their own lessons and tests, the books are mainly for help, books are not automatically the lessons.
For national tests (such as Baccalauréat), they are made by government employees.

I see a few differences with US:
- All the tests/exams are made public after the start of the exam.
- Since France is spread all other the earth (Europe, Latin America, Pacific ...), there are different set of questions for different places for the same exam.
- Students can get back its corrected answers after the exam.
- The tradition is "open" questions for exams: In the exam, the student get only the questions, not the candidate answers.
