By visiting this website you have some idea that Continuing Professional Development (CPD) is required by your registering body.
It is best that you read what is required for your specific profession as each body will have a guide on their websites. A common theme is that a variety of CPD is needed and that a little more often is a preferred way. The key is recording everything as you do it as it is easy to forget what you have done it a couple of months later.
Reflection is also important and a requirement of many registering bodies. There is a reflective template on the site you are free to use.
