How long does a private ADHD assessment take?


The clinical assessment appointment itself typically lasts 60 to 90 minutes. Before the appointment you will complete pre-assessment questionnaires — for children these include Conners 4 rating scales completed by both parents and teachers. After the appointment, your full written diagnostic report is typically provided within two weeks. The total time from booking to receiving your report is usually four to six weeks depending on availability. For children, school input is required before the assessment can be completed, so it is important to arrange this promptly after booking.
