A-levels still tend to be the gold standard for employers. Many organisations seek evidence of a good academic attainment – which A-levels indicate – and will then offer their own vocational training programmes.
A recent CBI report confirmed that a degree in science, technology, engineering or maths (the so-called STEM subjects) gave undergraduates a clear advantage in the jobs market. The A-level route is usually needed for such degree subjects.
In a nutshell, if your daughter is reasonably good at passing written examinations, I would recommend the A-level route so that she keeps her future options open.
