An understanding of consultant-level practice across your specialty is required. Based on this understanding, you should decide the type and number of submissions that will be most appropriate to demonstrate achievement of the learning outcomes and the Higher Specialist Scientist Standards of Proficiency.
It is important to emphasise that within the HSST there is no required use of particular assessment tools (DOPs, CBDs etc) at particular stages of your training. You and your Supervisor should discuss and agree on what is most appropriate for you in the consultant role for which the HSST is preparing you.
It is useful to think about your e-portfolio as your personal portfolio which clearly demonstrates all your learning, development and assessment activities. Your portfolio evidence will be reviewed by your Supervisor as part of the Annual Review of Progression, therefore it is important that you capture sufficient, convincing evidence of your learning and development while on the programme.
The HSST assessment strategy is very much learner-led and this can be a tricky transition to make after years of experience of taught programmes with set assessment criteria. However, there are valid reasons for using this flexible approach. It allows trainees to undertake individual training programmes within their training centres which is aligned with their career goals.
