“Misguided school-age career counselling” is another problem, as it often suggests to young women that ICT careers are too hard or somehow unfeminine.
No they don't - they keep trying to convince young women that IT is cool, with things like Women in Science and Engineering. They have been doing this since I was at university, 30 years ago. The snag is, when older folk tell teenagers that something is cool, they will have actually convinced them of the exact opposite.
Another problem is that young women (and men) considering a career in IT may have noticed the impact of ICT* visas, where people from India are brought to the UK to fill IT jobs or the offshoring of IT jobs, all conspiring to reduce opportunities and salaries. They may also have noticed the significant percentage of graduates from IT related courses who cannot find employment. Careers in medicine, law or banking are likely to have better prospects and salaries, which is decidedly more cool than being jobless.
*ICT = Intra Corporate Transfer, a sneaky way to have someone working in the UK under Indian terms and conditions.
