Direct answer

Holistic scoring means examiners judge Writing as a whole performance across four criteria, but the weakest criterion often caps the task score. A Band 7 essay is not four averaged subscores; it is sustained evidence at Band 7 on Task Response, Coherence, Lexical Resource, and Grammar, with no criterion stuck at Band 6. AI tools that output one number without per-criterion evidence miss this ceiling logic.

How holistic scoring works in Writing

Whole-task view Examiners read TR, CC, LR, and GRA together, not grammar alone

Weakest-criterion cap One Band 6 criterion can hold the whole essay at 6

Task 1 + Task 2 blend Both tasks contribute to one Writing band

AI flattening risk Single-score AI hides which criterion leaks

Common holistic traps

Skill	Student belief	Examiner read
Grammar looks strong	Band 7 GRA	Essay stays 6.5 overall
Connectors everywhere	Band 7 CC display	TR still Band 6
Rare vocabulary	Band 7 LR spikes	Ideas under-developed

Train with criterion passes

Score TR only on a fresh essay, then CC, LR, GRA in separate passes.

Key takeaways

Holistic scoring caps at your weakest criterion, not your best paragraph.
TR and CC floors dominate Band 6→7 Writing jumps.
Per-criterion passes reveal the true ceiling.
Raising the floor criterion lifts the whole essay.
