I think you should go and have a chat with the management at the school to address the worries you have concerning this report. Explain to them where and why you feel hard done by, which will allow them to give their interpretation of how things stand. Remember, they will be just as keen on getting you employment as you are.

p.s. a friendly tip - don't go putting the name of your instructor on a public forum without seeking his permission to do so first, he may not appreciate you doing so.
