It is not necessary for assessors to have prior knowledge of a trainee when completing a WPBA, but they should be a Consultant, SpR, StR, Associate Specialist, or senior nurse, psychologist or social worker who feels confident to assess the case.
For CT1-CT3 trainees; nurses, psychologists and social workers at band 7 or equivalent can be assessors.
For ST4 - ST6 trainees; nurses, psychologists and social workers at band 8 or equivalent can be assessors.
CT1-CT3 trainees cannot assess each other and ST4-6 trainees cannot assess each other but ST4-ST6 trainees can assess Core trainees.
Trainees should try and use a range of different assessors (ideally a different one for each assessment).
As always, we would recommend that trainees check with their educational supervisor if they are unsure about the suitability of a particular assessor.
