While you are out of practice, it is best to develop a Personal Development Plan (PDP) so that you can evaluate your current knowledge and skills and to identify any knowledge and skills gaps especially in relation to your intended future roles. If you are still registered with the GPhC, your online CPD recording system has a PDP template which you may find helpful.
If you have not been on the GPhC register for more than 12 months, you will be expected to submit a portfolio of evidence of current competence and also a PDP as part of your application for returning to the register.
It is always good practice to keep a learning portfolio (especially when you are out of practice) so that you can use this portfolio to collate your evidence in preparation for your return to practice. This could then be updated to suit the GPhC's requirements,if you decide to submit a registration application.
As part of your learning portfolio you can use the CPD framework and your PDP to identify areas you feel you need to develop, against the competencies for the role you will undertake. In this way, you can start from reflection and work through a complete CPD cycle for each of the areas identified. You may also become aware of additional learning that you need to undertake and this can be recorded by starting a new CPD cycle.
