Hi!
Your comment is really interesting!! It depends on social and cultural backgrounds!
I watch many American movies and it seems that to be suspended is something really serious for them!
Here in Portugal being suspended had some serious consequences some time ago: you could have to repeat the year because of the classes you missed! If a student is over 15 he can fail the year if he misses too many classes (and when he is suspended he/she cannot justify why he missed school- so it�s a punishment)
Nowadays, since our minister of education is a real misery, suspension doesn�t have that effect... unless the parents are strict and the student knows he/she will get in real trouble.
Here in portugal (and at my school) we call parents to school and sometimes give students extra work, such as helping to take care of the gardens, canteen...
But in USA (at least from what I see in the films) students can be expelled from school
Bye
