The attitude towards students who were less able than others is awful. Actively bully or put down students who didnt perform as well, and no praise given when that student does extra work on that topic - only criticism.
"We're counting down the days till you've left". Unacceptable to hear from Teaching staff from the School, especially from a Head of Department, regardless of the situation.
Grudges often kept from previous years despite offering a clean slate for the move up to GCSE year or A levels.
Teachers would actively lie to justify their reasoning's against a student, and would actively try to remove students from the course despite results or work shown.
All in all, the attitude towards students who try to achieve highly but cant quite meet their upper-tier piers is disgusting - could be counted as bullying. Psychologically damaging.
