Personas without made up stuff?

I am currently putting together some personas and am creating a template that will be informed by user research. What I'm attempting to do is avoid the classic 'assumptive' persona and avoid adding made up stuff. For example I don't want a fake name but will call my first user type 'Student'. I'm not using a fake portrait but use an icon or illustration.

The question is, has anyone done this or seen examples of truthful, non asumptive personas?

I essentially want a persona which people can use and not have to guess what has been filtered out or made up. Suggestions?
