Gillick competence refers to a judgement about the whether the understanding and intelligence of the child is sufficient to consent to treatment. Gillick competence needs to be assessed on a decision by decision basis, checking whether the child understands the implications of the treatment. Consent needs to be given voluntarily. When prescribing contraception to children under 16 it is important to assess for coercion or pressure, for example coercion by an older partner. This might raise safeguarding concerns.
