Understanding Work Based Assessment and CBD

In Competence by Design (CBD), competency involves more than ‘know how’. It requires that trainees also ‘show how’ and demonstrate the ability to ‘do’ independently. While learning is often associated with teaching, there is also high value in using assessment as a learning tool.

Work based assessment (WBA) maintains this formative focus by having frontline clinical teachers observe and document authentic observations in the workplace on a regular basis. The results of individual assessments are shared with trainees in a way that guides learning improvement. When these individual work based assessments are aggregated over time, the data from multiple observations and multiple sources gives a clearer picture about a trainee’s performance and progress.

Clinical Teaching and Assessment (Observe, Feedback, Document)

In CBD, frontline clinical teachers do not make judgements about learners. Instead the expectation is that they observe trainees in practice and provide written-verbal feedback designed to promote learner growth. Feedback is documented in various work based assessment (WBA) tools chosen by individual specialty committees and programs. Completing WBA tools involves clinical teachers rating learners practice performance using entrustability scales and detailed narrative descriptors.

What is an entrustability scale?

These scales use entrustment anchors to rate a trainee’s ability to safely and independently perform practice activities indicative of EPA achievement. Entrustment anchors align well with expert observer performance judgements and are shown to be highly reliable compared to traditional WBA rating scale anchors. The following entrustability scale is incorporated within several WBA tools endorsed by The Royal College.

WBA and learner promotion

One goal of work based assessment is to collect as much information as possible about a learner, from as many sources as possible. Over time this data is pooled together to create a comprehensive image of the learner’s competence and help inform competence committee discussions about resident promotion. By shifting these broader promotion discussions to the competence committee, interactions between individual learners and observers can focus on coaching feedback designed to help improve learners’ performance.

WBA tools in practice

In CBD, both trainees and observers initiate practice observations. These may be direct or indirect. Optimal performance feedback results from direct observation, however this is not always feasible given workflow demands or desire for increasing trainee independence. Regardless of the WBA tool used, or whether observations are direct or indirect, clinical teachers assessing trainee performance should remember:

  • Narrative comments focused on behavior specifics are the most valuable information in any WBA tool. Good comments provide trainees with detailed guidance for improvement and competence committees with rich context for the performance ratings.
  • Isolated practice activities are linked to, but not inclusive determinants of EPA achievement (e.g. performing a knee exam is only one part of the osteoarthritis management EPA).
  • WBA tools provide performance rating information and feedback specific to only that activity and context. As an observer, you are not deciding a trainee’s overall competence moving forward.
  • Trainee progression decisions are informed by multiple observations using an entrustability scale.
