How to get a better idea of the situation? One ought to ask people who have own exoerience of school. Is there any clear idea of what kind of school was good for life, and what on the other hand was no longer motivating or folliwed, or was opposed. Tens of years ago in my school in Helsinki, it seemed to be so that the five first years of school were ok, but 6th grade and after that even teachers said as their estimate that school did not work like was the idea in having a school, and that something ought to be done to correct the school to much better, or maybe re-estimate how many years of school and find other alternatives, for example studies to a profession that one likes. If many teachers and adults share the same observations, it is easier to improve school.
