How to Score a Perfect 25/25 in Selective Writing: The 2026 Masterclass — Selective online practice for the NSW exam

Scoring a perfect 25/25 in the NSW Selective High School Placement Test Writing section is rare. It is the only part of the exam marked by human beings, which means you aren't just trying to beat a computer algorithm—you are trying to captivate a tired marker who has read hundreds of responses that exact same day.

With the 2026 format locking in an equal 25% weighting and a strict 30-minute digital timer, a perfect score requires more than just a good imagination. It demands strategic precision, technical flawlessness, and a deep understanding of the marking rubric.

Here is the ultimate guide to scaling that mountain, including a real-world breakdown of what separates an average story from an exceptional one.

Understanding the 2026 marking rubric

To get a perfect score, you need to know exactly what the two independent markers are looking for. Your 25 marks are split into two distinct categories:

Set A: Content, form, and organisation (15 marks) — This is about what you say and how you structure it. It assesses your originality, your ability to stick to the prompt, and the logical flow of your paragraphs.

Set B: Technical accuracy (10 marks) — This is about the mechanics of your language. It assesses spelling, punctuation, vocabulary choices, and sentence variety.

To score 25/25, you cannot drop a single point in either set. Here are the elite tips to ensure you maximise your marks.

Tip 1: The "unique angle" strategy (maximising Set A)

When students see a stimulus—for example, a picture of a locked door—90% of them will write a predictable story about a haunted house or a secret treasure. Markers call this the expected response.

To score 15/15 in Set A, you must provide the unexpected response.

The strategy — Take 60 seconds to brainstorm the most obvious ideas, and then throw them away. Force yourself to find a different perspective. Instead of writing about the person trying to open the locked door, write from the perspective of the person hiding behind it. Originality is heavily rewarded.

Tip 2: Master the "show, don't tell" evolution

Markers are looking for sensory language that creates an immediate atmosphere.

Average (telling) — The weather was really bad and John was scared.

Band 6 (showing) — Rain hammered against the tin roof, drowning out the frantic thud of John's heartbeat.

The upgrade — Delete your adverbs (words ending in -ly, like really, very, quickly). Instead, upgrade your verbs. Don't say someone "ran quickly"—say they "sprinted" or "bolted". Strong verbs earn high marks in both Set A (style) and Set B (vocabulary).

Tip 3: Technical flawlessness and the 5-20-5 strategy

Because there is no spell-check in the 2026 digital test interface, your raw typing accuracy is critical. You must ruthlessly manage the 30-minute countdown to ensure you have time to edit.

0–5 minutes (plan) — Deconstruct the prompt. Choose your text type. Dot-point your beginning, middle, and end.

5–25 minutes (draft) — Type your response. Aim for 350–450 high-quality words.

25–30 minutes (polish) — This is where you earn your final marks. Fix any typos. Upgrade three boring words to high-level vocabulary. Check your punctuation.

The masterclass: Putting it into practice

To see exactly how this rubric is applied, let's look at a practical example. We will use the same prompt, the same core idea, and a strict ~330-word limit to demonstrate how execution, rather than length or wild ideas, dictates your final score.

The prompt — Write a narrative about a difficult choice between loyalty and honesty.

The core idea — The protagonist sees their best friend steal a USB drive from a strict teacher's desk.

Draft 1: The 15/25 response (average / Band 4)

Leo and Sam were best friends. One day after school, Leo was waiting for Sam in Mr. Harrison's classroom. Mr. Harrison was the strictest teacher in the school. While Mr. Harrison was looking away, Leo saw Sam take a shiny silver USB drive from the teacher's desk and put it in his pocket. Leo was shocked. He didn't know what to do.

The next day, Mr. Harrison stood in front of the class. He looked very angry. "Someone has taken my USB drive," he said loudly. "It has all my important files on it. If the person who took it doesn't confess, the whole class will stay in during lunch."

Leo looked at Sam. Sam looked down at his desk and didn't say anything. Leo felt really bad. He knew he should tell the truth, but Sam was his best mate. If he told on Sam, Sam would get in huge trouble and probably wouldn't be his friend anymore. But if he didn't tell, everyone would miss out on lunch, which wasn't fair.

Leo raised his hand slowly. His heart was beating very fast. "Mr. Harrison," Leo said, his voice shaking. "I know who took it."

Mr. Harrison looked at him. "Who was it, Leo?"

Leo took a deep breath. "It was Sam," he said.

Sam looked at Leo with a betrayed expression. Mr. Harrison told Sam to go to the principal's office. After class, Leo tried to talk to Sam, but Sam walked away. Leo felt sad that he lost his friend, but he knew he did the right thing in the end because honesty is the best policy.

The critique (why this scores 15/25)

Set A (content and form — 8/15) — The narrative has a clear beginning, middle, and end. However, it relies heavily on clichés ("heart beating fast," "honesty is the best policy"). It simply narrates a sequence of events without exploring the emotional weight of the choice.

Set B (technical accuracy — 7/10) — The spelling is correct, but the grammar is basic. Almost every sentence is structured the same way (subject–verb–object). It relies on telling rather than showing (e.g. "He looked very angry" instead of describing the anger).

Draft 2: The 25/25 response (exceptional / Band 6)

The silence in Mr. Harrison's classroom was suffocating, broken only by the rhythmic ticking of the wall clock. From my desk in the back row, I watched a shadow detach itself from the doorway. It was Sam. His hand darted out like a striking snake, snatching the silver USB drive resting on the teacher's pristine desk before retreating into his pocket.

My breath hitched. Sam, the boy who had shared his lunch with me since Kindergarten, was a thief.

The inevitable interrogation arrived the following morning. Mr. Harrison's face was a mask of barely contained fury. "The drive contains the entire term's examination papers," he announced, his voice slicing through the quiet room. "Unless the culprit steps forward, the Year 6 excursion is cancelled."

A collective gasp echoed off the linoleum floor. I glanced at Sam. He was staring intensely at his shoelaces, his knuckles white as he gripped his desk. A heavy knot formed in my stomach, twisting with every second that passed. If I remained silent, forty students would pay the price for a crime they didn't commit. If I spoke, I would be signing the death warrant of a lifelong friendship.

Loyalty and integrity waged a violent war in my mind. Was friendship simply a shield we used to hide each other's flaws? Or was true friendship having the courage to stop someone from becoming the worst version of themselves?

The wall clock ticked loudly, counting down the seconds of my silence. The pressure in my chest expanded until it demanded release.

"Sir." The word tasted like ash in my mouth.

Twenty heads swivelled toward me. Sam's eyes met mine, widening in sudden, panicked realisation. I saw the plea in them, the silent, desperate begging.

I closed my eyes, shutting out his betrayal, and forced myself to sever the bond. "I saw who took it."

The reasoning (why this scores 25/25)

Set A (content and form — 15/15) — The plot is the same, but the execution is deeply engaging. The writer uses the ticking clock to bookend the story, creating a cyclical, complete structure. The protagonist's internal monologue actually questions the meaning of the prompt ("Was friendship simply a shield..."), showing high-level maturity and original thought.

Set B (technical accuracy — 10/10) — Exceptional control of language. The writer uses powerful, precise verbs and imagery (suffocating, pristine, slicing, sever). They successfully use show, don't tell ("knuckles white as he gripped his desk" instead of "Sam was nervous"). The sentence variety is excellent, mixing short, punchy sentences ("It was Sam.") with complex emotional descriptions.

The final reality check

Scoring 25/25 means taking a risk with your ideas but being incredibly disciplined with your grammar. It requires regular, timed practice on a computer keyboard so that the physical act of typing becomes second nature, freeing up your brain to focus entirely on crafting a masterpiece.
