An incentive for writing a school story

You remember or experience a situation in which a school system representative (teacher or director)
lied on an important issue, let's say a grading in a central subject.

What could you do with such an event to make it the core of a school story?
 
- Let the student tell about his disappointment being lied to on grading by a teacher/director
- Describe the student who really needs a good grade in this very subject
- Imagine the lots of work she/he did to improve in the coming school report
- Mention the progress that was visible in the tests and papers
- Show how friends and parents where happy that things got better
- Move the story to a point where it seems absolutely clear that improvement was done
- Depict a little scene where the teacher giving the grade was angry about this student
- Give some background why he felt motivated to refuse the better grade finally
- Tell details about his close relation to the director who wants bade grades at his school
- Let him utter some of the spreaded teacher rubbish about "good teachers give bad grades"
- Make a hint on the school system based on a scale of 5 or 6 grades that must be applied

So far, this might be enough. Can you use such a list of incentives to write a school story?

Use your fantasy, and you will find a beginning, an end and of course your own central action part.

My idea is, lying as one of the typical patterns of school life, used every minute at every school, especially by the weak characters that work there and are asked to educate young people. The reason is: the system awards them for lying, and they get punished for telling things as they are.The problem is: the leaders of the school system, directors and supervisors on higher levels, stick too often to the rules of lying, simply to avoid questions and quarrels.
