Once admitted, those wishing to practise as barristers must contact the relevant bar association to register and sit the bar exam. The frequency and availability of these exams depends on the relevant bar association. Generally, the bar exams focus on three main areas of practice which are relevant to barristers; namely evidence, procedure and ethics. The exams are usually administered during the course of a day and comprise a variety of question types, usually answers are given in essay form. Candidates are informed of their results within a few months and pass rates are very competitive. Passing the bar exam in and of itself does not automatically allow one to practise as a barrister, in many jurisdictions (such as New South Wales) further requirements apply.
