Absolutely fine mate - glad to help. I started on a YTS, at 16, as a trainee quantity surveyor then building surveyor in a VERY small private practice on colledge day release for my ONC and HNC in Building Studies.
Uni, and did a degree in Building Surveying then "drifted into" project management through an employers agent / project surveyor natural progression. Been with a multi national developer . contractor / consultancy now for some time (10 years this year) and currently a Senior Project Manager in the Consulting business of the company.
If she is already working I would suggest she looks at the APM website
http://www.apm.org.uk/ and looks at the entry requirements and what is needed for the first step of membership. They acknowledge that everyone has to start somewhere and she may well be surprised at how much she does now can contribute to gaining experiences towards the nest stage. By applying and getting even the lowest "grade" of membership she is still, non the less, a member of a professionally recognised PM body.
Every sector is different (im in construction) so she would need to see what she can do in her current employment and role which is applicable, I would also suggest she then looks at what she needs to progress and speak with her line manager as part of annual assents and goal setting. These goals could be aligned with the APM requirements and she could (hopefully gain good recordable and acknowledged experiences) whilst with the same employer (if that s what she wants).
All in all this would be cheaper that a Prince2 course and a better long term investment.

I keep getting threatened to be sent on the Prince2 courses as I work predominantly for Public Sector Clients and they tend to call for P2 experience or qualifications on fee bids.
I have noticed more and more that it now just coming down to price
