It is always a good idea to have an up to date CV, and not just because you need one for your progress file. If you apply for a job, a course, or work experience, it is a great way to let everyone know what qualifications and skills you have. You should update your CV at least every year and add in any new qualifications or achievements. A template for your progress file CV is here.
