Splitting Marks When the Ensemble Is Uneven
A SACE Stage 2 ensemble of five performs well overall, but the contributions are uneven. The vocalist carries the melody confidently and shapes phrasing; the keyboard player is secure but plays mechanically; the bassist and drummer lock together well; the rhythm guitarist has several wrong chords in the second work. The teacher must assign individual results for an ensemble performance. The school's advice is that each student is judged on their own contribution within the ensemble, and that the ensemble's overall cohesion is also relevant. Two students' parents have asked why their children might receive different results for the same performance. The teacher must decide how to differentiate and how to explain it.
1. Explain how the teacher should differentiate individual results within a single ensemble performance.
Read the worked answer
Differentiation is required because the assessment is of each student's contribution, not a single group score.
How to differentiate:
- Identify each student's audible role and judge accuracy, control and musical decision-making within it.
- The vocalist's confident phrasing and the rhythm guitarist's wrong chords are both observable and specific; they should not be averaged into one group impression.
- The keyboard player's mechanical playing is a genuine interpretation weakness even though the notes are secure; accuracy alone is not the criterion.
- The bassist and drummer should be credited for the locked groove, which is ensemble evidence, while recognising that their individual lines may be simpler.
Avoiding distortion:
- Do not let the strongest player's performance lift a weaker player's result, or vice versa.
- Do not penalise a player twice for the same error.
Explanation to parents: the same performance can yield different results because the criteria apply to each student's own contribution, and the comments name the specific evidence.
2. The rhythm guitarist's parent argues that the wrong chords are the group's problem because the ensemble should stay together. Evaluate this argument.

The argument has a grain of truth but does not transfer responsibility for the errors.
Where it is right:
- Ensemble cohesion is a shared criterion, and the group's ability to cover or recover from an error is relevant to everyone's judgement.
- If the group stopped or lost tempo because of the wrong chords, that is a shared cohesion issue.
Where it is wrong:
- The wrong chords are an individual accuracy error. Another player cannot prevent a chord being played incorrectly.
- Treating the error as purely collective would remove individual accountability, which the assessment requires.
Fair treatment:
- Record the specific wrong chords and their frequency in the second work.
- Note whether the group recovered smoothly, and credit that recovery to the ensemble.
- Judge the guitarist on the accuracy of their own part, while the group's recovery is reflected in the cohesion comment.
Conclusion: the parent's point should be acknowledged and then distinguished: shared recovery is credited, individual errors are attributed.
3. The teacher must write comments that justify the differentiated results. Explain what makes a comment defensible to a moderator and to parents.
Read the worked answer
A defensible comment is specific, evidence-linked and criterion-referenced.
Qualities of a defensible comment:
- Specific: names the work, passage or moment, such as wrong chords in the second work rather than vague praise or criticism.
- Evidence-linked: points to what is audible in the recording, with timestamps where possible.
- Criterion-referenced: connects the observation to accuracy, balance, interpretation or cohesion, not to effort or personality.
- Proportionate: weighs the observation against the student's other contributions, so one error does not define the result.
- Consistent: uses the same standards across all five students, so the differentiation is explainable.
For parents: translate the criteria into plain language and show the specific evidence, avoiding comparison with other named students.
For moderators: keep the comments aligned with the recording, so the moderator can verify each claim. A comment that cannot be checked against the recording is a liability, not a justification.
