"Why aren't these events held in yrs 7 or 8 long before the students select GCSE options that might then narrow their choices later on?"
This is actually a really good question. I know that some large organisations where it's all about people - think accounting, consulting, law firms etc - have long had mentoring programmes, formal and informal. Then when they realised women weren't on these programmes, they created women only programmes. But it didn't have the impact they hoped.
The next step that these firms are now focusing on is the realisation that often by the time these mentoring programmes kick in, the relevant individuals have already decided whether or not this is a long term path for them - ie to make partner or similar according to industry. And for the women, with all the mentoring in the world, they'd already decided it wasn't for them because of all kinds of reasons. So now, HR teams are looking at introducing mentoring for women at a much earlier stage in their careers. ie, rather than waiting for the best to start rising to the top and them help to accelerate that, they're trying to get in early so that the women who are talented and have potentially excellent careers within these organisations do thrive within them, and, importantly, stay.
I'm not sure if there's much data on the success of this type of programme as yet. I'm more aware of research that shows where the problem starts and this is just the currently proposed solution. But it would be interesting.
And certainly, from my own perspective, I was extraordinarily ambitious as a teenager and in my early 20s. But as I worked in large global organisations, I increasingly questioned whether being at the top within my field in one of these was something I wanted. I wasn't sure about the culture and the sense that you practically had to give up your soul to do it. I also started to get frustrated by the number of times I would do brilliant work but get just a fraction of the credit a man doing similar, or sometimes worse, work would get. Promotion opportunities always seemed to be less for me.
And sure, you could say that was just me. But I have enough happy clients and ex colleagues to know that my competence wasn't in question.
With these mentoring programmes of course, the big problem is whether they help to shift th culture. Because from my experience (and I don't think I'm alone in this - I've got female friends with similar experience) the thing that pulls you down is a combination of being looked over (which mentoring might solve) and the fact that the appeal of the "big job" lessens as you see what sacrifices you have to make elsewhere.
