How the CT rubric dimensions work
Task A is scored on three independent dimensions and Task B on two; each has its own pass line, so one weak dimension can fail a task.
The CT rubric uses bands from 1 (highest) to 5 (lowest). For Task A, meaning transfer and language proficiency require Band 2 or above, while application of textual norms and conventions requires Band 3 or above. For Task B, revision skills require Band 2 or above and error categorisation Band 3 or above.
Because the dimensions are scored independently, an excellent score in one cannot compensate for a weak score in another. Pass-line numbers are also not comparable across dimensions: always read each band against its own descriptor.
