PGCE Reference

I need to ask a university teacher for a reference but none of them really know me that well, despite me being in final year. Should I ask my personal advisor for one? She is also a lecturer but has not taught me yet and I've only been to see her twice, lol. Please help

I asked the former head of department three years after graduating. I wasn't sure she would even remember me, but she was more than happy to write one. They are used to dealing with requests like this. Remember, it's an academic reference, not a personal one, so they don't need to know you well on a personal level. They just need to be able to comment on your academic performance and suitability for teaching from an academic perspective. Your personal advisor should be able to gather information about you from various sources to write one.

Ok cool, thank you! Also, they say the second reference needs to be from a professional, who can comment on my suitability for teaching - I worked in a little independent shop over the summer... would the owner be a suitable referee? Or would I be best asking the headteacher of the school where I obtained experience? (this was only for 10 days)

Go with whomever is going to be able to justify why you are suitable for teaching and comment on your character accurately. Would the shop owner be able to provide examples of times you demonstrated some of the qualities needed to be a good teacher? Does the headteacher know what you did whilst you were at their school or be able get sufficient information from the class teacher?
