Continuing Professional Development. Your CPD is your ongoing learning. Nurses are lifelong learners. You will do and learn new things all the time as you, the public, patients and healthcare are always changing. It is your experiences, your knowledge and skills in theory and in practice. It can be formal or informal. A qualification say, or possibly how you made a difference with a patient by the caring way you communicated with them. It all counts. There is always something we can continue to learn about to grow.
