To draw a parallel, there are Golden Hellos of up to £25k for STEM teachers (in 2007, it was £6k; in 2011, it was £9k. At this rate, it will be £50k by 2018 and they still won't get anybody)
Actually recruited as of last month......
According to the Department for Education, some 32,543 people started – or expect to start – teacher training courses this term, compared with a target of 34,890. It represented 93 per cent of the total.
But figures showed much larger under-recruitment in some vital disciplines, despite the promise of tax-free scholarships of up to £25,000 to attract the brightest graduates.
In design and technology, only 44 per cent of places were filled, while the recruitment rate stood at 67 per cent for physics,
Government comment
"Despite a tightening labour market, trainee teacher recruitment is holding steady - with low vacancy rates in priority subjects like maths and science.
Vacancy rates are low because it is allowing schools to recruit non-specialists. In difficult areas, students can now do entire GCSE Maths courses without having a single lesson from a Maths specialist. And these are the kids that the military is trying to recruit.
But it's not just recruitment; look at retention.
40% of new teachers leave the profession within 5 years.

In summary, the Government has its head in the sand about the problems, is announcing ever increasing headline amounts and levels of confidence, and facing ever decreasing rates of recruitment and retention.
The same applies to the military. Golden Hellos do not work when the major faults causing people to leave remain.
You should never try to bail the boat instead of fixing the leak.

p.s. In 2004, the Labour Government set a target of 25% of science teachers to be physics specialists, when the rate was 19% and decreasing. After 10 years of continuous effort by all three major parties, the rate is now(Dec 2013).....18%.
