My DD has recently gone through the process of applying for the Bar. He must go in with his eyes open but he does not have to decide which route at the moment.
The Bar Standards Board and the Bar Council have useful advice on training for the Bar. He does not have to do a LLB. It is worth noting that around 45% of Barristers do not have a LLB. What matters is that he has an academic degree from a top flight university. It is no co-incidence that around 40% of young Barristers are Oxbridge educated. The vast majority are from high calibre RG universities. A first is a great help but not vital. The Bar Standards Board produced excellent stats on this career and all their information is worth reading to make an informed decision. If he is commercially minded, a degree is Economics is no hindrance. However, I would have thought if he wants to work in England, do not do a law degree in Scotland.
You cannot mix and match specialisms at the Bar. Human Rights is ludicrously sought after and every single one of DD's friends who wanted to do it, did not get Pupillage. Criminal has more opportunities but remember that there are only about 450 pupillages on offer every year, but that 1400 approx are on the BPTC each year (the training course for the Bar). You can have several goes to get pupillage so at least 2500 can apply in any year. The majority of pupillages are in London.
The BPTC in London costs more than £19,000. So trainee Barristers need to get Scholarships from the Inns of Courts to help. Some of these are very generous but you need to be good. If you do not get a scholarship, the fees are more debt. The Inns also have scholarships for the pupillage year too if the pupil has a low pupillage award from a family or criminal set. The pupillages are offered by Barristers Chambers and they give a financial award ranging from £12,000 to around £70,000 p/a at the top end. Criminal will be nearer the bottom figure. Start looking at Barristers Chambers to see what area of work they do and pupillage information. Mini pupillages (work experience for one week) are available from many Chambers when the student is typically in 2nd year at university.
Many people love being a barrister but there has to be a strong desire to do it. Some family chambers at the top end make plenty of money but the work is very hard and unrelenting.
Building up a CV in your chosen field at university and whilst doing the BPTC is vital. Or even taking a year off between university and the BPTC to give you the edge in the area of work you want is common. People become Paralegals, do research, volunteer or do a Masters. There are lots of options.
This career is ultra competitive and university and degree count. Look at the Inns of Court for further information and go to as many events about law as he can (especially at university) so he is informed about which route to take. Do not believe anyone who says it is a breeze!
There are nearer 6000 training contracts to be a solicitor each year so, other than for the city solicitors, slightly less competition. You have to plan strategically. It is not for the faint hearted and it can result in huge disappointment for the majority. I lost many nights' sleep worrying about DD and her career.
