Not all roles fit neatly into sectors. Some just require specific levels of study or an advanced skill set. These kinds of jobs are often grouped together and called ‘professions’.
Roles within professions are hugely varied and cover everything from teaching to finance, legal work to marketing and scientific roles to publishing.
Routes into professions are as varied as the jobs themselves, but most will require higher study as they involve advanced knowledge in a particular area.
What matters most when you’re considering a career in the professions is that you choose something you’re passionate about because they give you the chance to really focus and dedicate your life a particular area of interest.
