# Scoring grounded in observable behaviour.

> TAP uses Behaviourally Anchored Rating Scales (BARS) and Behavioural Observation Scales (BOS) to make every score consistent, defensible, and tied to real behaviour.

Unstructured ratings are subjective and hard to defend. BARS and BOS anchor each score to specific, observable behaviours, so different assessors evaluate the same response in the same way — and every result can be explained.

## The methodology behind TAP scoring

- **Behaviourally Anchored Rating Scales**: Each rating level is defined by concrete behavioural examples, removing ambiguity from scoring.
- **Behavioural Observation Scales**: Assessors record how frequently key behaviours are observed, building an evidence-based picture.
- **Competency mapping**: Every exercise and item maps back to the competencies and behaviours it's designed to measure.
- **Consistency across assessors**: Shared anchors mean ratings stay consistent across assessors and cohorts.

## Why it matters

- Objective, behaviour-based scoring
- Consistent ratings across assessors
- Defensible, explainable decisions
- Clear link between evidence and scores
- Foundation for AI-assisted evaluation
- Aligned with assessment centre best practice
