Not a bad start, but I've got a couple of suggestions if you don't mind.
It may seem like there's not much to write down, but she should be able to expand a lot more on some of her work history.
If this has been mainly part time work while she's studying, she probably doesn't need loads of details under each heading - but she could do a little overview before she goes into the list of jobs that she's done.
I'd also try to tailor the CV to the job that she's applying for. There's a lot of competition out there for jobs (even part time ones), so she really needs to sell herself at the application stage.
There are slightly different skill sets for admin and sales jobs for example. So play up to the experience that is relevant to the job she's applying for. That might mean having 2 different versions of the CV on file, but it's worth the effort.
If there's a written job spec for the job she applies for, read it thoroughly and address all the requirements that they're asking for - even if that means yet another version of the CV
So bearing all that in mind, and going back to my point about expanding on what she's done and writing a summary of her work experience.
For example for an admin job, she could write something starting off :
"I have worked for Medway Council as an admin assistant for the previous two Summers, whilst continuing with my studies. . . Having worked there for 4 months in 2008, Medway Council were keen to re-employ me this year . . .This post has involved x,y,z . . . and has given me the opportunity to get a firm grounding in administration skills . . . "
Finally, have a think about the interests section.
I appreciate that this is only likely to be a part-time job until she finishes studying and not a career choice, but employers want to see a bit of enthusiasm about the job that you're applying for . . . even if it's not entirely 100% true.
As it stands, employers may read that section as saying "I want to be a professional hair stylist. That's where my interests lie. I just want this job as a stop gap."
While possibly true, it's not what employers want to hear.
Try to pick interests that say something about her ability to do the job.
For example for a sales assistant job, people skills are probably high on the requirements list. Try to find an interest where she can talk about how she enjoys the chance to meet new people etc etc.
Hope that helps.
And it's probably true!
