Writing is the part of exam preparation where families get the least help, because marking an essay well takes a skilled person real time. WritingHub is Test Academy’s answer to that bottleneck — an AI marker that grades a child’s writing against the real criteria in seconds.
What it actually does
A child writes a piece, submits it, and WritingHub returns four things almost immediately: a clear strength, a single specific next step, inline corrections marked through the text itself, and a style-matched exemplar — a model response written in a similar voice, so they can see exactly what “better” looks like for their piece rather than a generic ideal. Crucially, the grading is done against the same kinds of criteria used in the real exam, so the feedback maps to what actually earns marks.
Why it matters for results
Writing improves through a tight cycle: write, find out precisely what worked and what didn’t, revise, repeat. The thing that normally breaks that cycle is the wait — a piece handed in on Monday comes back the following week, by which time the child has moved on and the feedback lands cold. WritingHub compresses the loop to a single sitting. A child can write, read the feedback, and rewrite there and then, which is when the lesson actually sticks. And because the feedback is shaped as one strength and one next step, it’s something a young writer can act on, rather than a discouraging wall of corrections.
Why it’s ahead of other Sydney centres
This is a defensible technology advantage, and writing is exactly where it bites hardest. Human marking of writing is slow and expensive, so most centres can only return marked pieces occasionally and with a lag — which means a child writes far less, and waits far longer for feedback, than the skill demands. An AI marker that grades against the real criteria in seconds removes both constraints at once: a child can write often and improve fast. Getting that marking genuinely useful — specific, criterion-aligned, paired with a style-matched exemplar — is hard, and it’s not something a generic grammar checker or an occasional human red pen can replicate.

Marked against the real criteria
WritingHub grades against the same kinds of criteria used in the real exam, so the feedback maps to what actually earns marks rather than vague impressions.
Feedback in seconds, not days
A child can write, submit, and act on the feedback in the same sitting — instead of waiting a week for a marked piece to come back cold.
A strength and a single next step
Every piece comes back with one clear strength and one specific thing to improve, which is far more actionable for a child than a wall of red ink.
A style-matched exemplar
It shows a model response written in a similar style, so a child can see exactly what 'better' looks like for their own piece, not a generic ideal.
