Portfolio Station & Self-Assessment

CST Interview Guide

Portfolio Station


For 2027, the Portfolio station accounts for 45% of the final CST selection score and lasts 15 minutes. Candidates are required to upload supporting evidence of their achievements, which will be assessed against the updated portfolio scoring criteria.


The prepared presentation is now included within the Portfolio station, rather than the Management station.


Portfolio Station Structure (15 Minutes)


  • 3 minutes: Prepared presentation

  • 2 minutes: Questions relating to the presentation

  • 5 minutes: Portfolio question 1

  • 5 minutes: Portfolio question 2

The two portfolio questions focus on Patients, Partnership and Communication and Colleagues, Culture and Safety.

Portfolio Evidence

Candidates must upload a portfolio index and supporting evidence during the designated upload window (19–24 February 2027). Achievements are assessed using A–E grading indicators, with assessors reviewing the submitted evidence alongside interview performance.


We recommend reviewing the official 2027 portfolio guidance carefully and ensuring all achievements are supported by appropriate documentation.
