PRINCE2 Practitioner certification is suitable for anyone managing projects. This could be as part of a formal project management function or a role which involves project management as part of day-to-day work. The Practitioner certification aims to confirm that you have sufficient knowledge and understanding to apply and tailor the method in a range of different project environments and scenarios.
Attaining your Practitioner qualification is only one part of becoming a successful and effective project manager. It is important to ensure that you supplement this with real-life experience working on projects, in addition to investing in personal professional development and wider training.
