Now that I've been in the UK long enough to qualify for home fees, I'm starting to look into going for my PhD. The biggest thing that worries me is the references requirement. I completed my masters degree in 2003 in the US, and haven't been in touch with any of my professors since then. Plus, I was a good but not great student, and I'm concerned that if I try to contact them to ask for references, they will a) not remember me after all this time, or b) remember me, but not favourably enough to write a reference. My favourite professor, the one who brought out the best in me as a student, has long since retired and I don't know if I can track him down. Even if I could, he is in his eighties by now and I'm not sure what his memory is like.
Does anyone know what universities are hoping to learn from referees? All my former professors could really attest to is what I was like in my early twenties studying a subject that I enjoyed but wasn't passionate about. Now I'm ten years older and have found something I genuinely love and want to study. I don't think that who I was then is in any way relevant to who I am now and what kind of student I would be. I understand that referees don't have to be academic ones, but then how would my colleagues be able to speak to my abilities as a student when they only know me from work? Is it worthwhile to try to track down my favourite professor in the hope that he will remember me, or will colleague references be enough? Is it important for referees to be distinguished/successful people? Anyone who got into a PhD programme in the UK after 10+ years away from higher ed, what referees did you use?
Thanks in advance for any advice.
