Secondary School English Writing: What Teachers Actually Look For
Published 13 June 2026
Most students approach English essays by trying to write well in a general sense — using “good words,” writing long sentences, trying to sound formal. Most parents don’t know what criteria the teacher is using at all.
The result is a lot of effort spent on things that don’t move the grade, and persistent weaknesses in areas that do.
Understanding how essays are actually assessed — what teachers are trained to look for and reward — changes how you practise and where you focus. Here’s what secondary school English teachers, and the exam marking schemes they follow, are actually looking for.
The Four Dimensions That Are Always Being Assessed
Across different school systems and exam boards — HKDSE, Cambridge IGCSE, PSLE, SPM, O-Level — English writing is evaluated along broadly similar dimensions. The specific weighting varies, but these four categories are nearly universal:
1. Content — Does the essay address the task? Is there enough information, detail, and development of ideas? Is it relevant throughout?
2. Organisation — Is the essay clearly structured? Does it have an opening, a body with developed paragraphs, and a conclusion? Does it flow logically from one idea to the next?
3. Language accuracy — Are the grammar, spelling, and punctuation correct? Is the vocabulary used correctly? Does the language get in the way of understanding?
4. Vocabulary and expression — Is the language varied and precise? Does the student use a range of vocabulary rather than the same words repeatedly? Is the tone appropriate to the task?
Most students — and parents — focus almost entirely on the fourth category because “good writing” feels like it means using impressive vocabulary. But in practice, Language accuracy (category 3) is often where secondary school students lose the most marks, because recurring grammar errors are very visible to trained assessors and directly affect how much the reader trusts the writing.
What “Language Accuracy” Really Means
When a teacher marks an essay for language accuracy, they’re specifically looking at:
- Grammar: Are verb tenses used correctly and consistently? Is subject-verb agreement applied? Are sentences complete (no fragments)?
- Spelling: Are commonly used words spelled correctly? Are high-frequency academic words spelled accurately?
- Punctuation: Are full stops, commas, and apostrophes used correctly?
- Word choice: Are words used in their correct sense? (Using effect when you mean affect, for example, signals vocabulary confusion rather than vocabulary richness.)
A single grammar error in a 300-word essay is noticed but doesn’t usually change the mark significantly. Persistent, recurring errors — the same mistake appearing four or five times — signal a pattern that assessors are trained to recognise and penalise.
This is why the most common secondary school grammar errors (tense inconsistency, subject-verb agreement, missing articles) matter so much: they tend to recur throughout an essay rather than appearing once.
The Invisible First Impression
Teachers who mark large volumes of essays report something that doesn’t appear in any rubric but is consistently reported: the opening paragraph creates a strong impression that colours how the rest of the essay is read.
An opening paragraph with multiple grammar errors immediately signals a weak language foundation. The teacher may not consciously intend to mark down the rest of the essay based on this — but research on marking psychology suggests that first impressions are difficult to fully correct for.
Conversely, a clean, clear opening paragraph — even in a simple, direct style — signals to the teacher that the student can write competently, and the rest of the essay benefits from that expectation.
Practical implication: help your child write a clean, clear first paragraph. Not impressive — just correct and relevant. This is often the highest-impact improvement available for a short amount of effort.
What “Organisation” Looks Like in Practice
Teachers are specifically looking for:
A clear opening that signals the essay’s topic or argument. The first paragraph should tell the reader what the essay is about. It doesn’t need to be elaborate — “This essay will discuss…” is fine for secondary level — but it needs to be present and relevant.
Paragraphs that each have one main idea. Every paragraph should be able to be summarised in one sentence. If a paragraph covers three different points, it will read as chaotic even if each individual sentence is correct.
Connecting language between paragraphs. Phrases like “Another important point is…”, “However,”, “As a result,”, “In contrast,” signal to the teacher that the student understands how to build an argument. Students who use these connectors tend to score better on organisation even if their ideas are not particularly sophisticated.
A conclusion that doesn’t just repeat the introduction. A weak conclusion (literally restating the opening) is better than no conclusion at all — but a conclusion that adds something, even briefly, scores meaningfully better.
The Vocabulary Trap
Many students and parents think that using “big” or “impressive” words will raise the language score. This is partially true but frequently backfires.
Using a sophisticated word correctly impresses an assessor. Using a sophisticated word incorrectly — whether the meaning is wrong or the context is unnatural — is a red flag. It signals that the student is reaching beyond their actual vocabulary range, and it draws attention to other potential weaknesses.
The safer and more reliable strategy is to use words you’re certain of and use them precisely. A student who uses the word significant correctly ten times will score better than a student who uses momentous twice in ways that feel slightly off.
Vocabulary range is built over years, not weeks. In the short term, the highest return on effort is accuracy: use the words you know correctly, vary your sentence structure, and don’t make avoidable errors.
How Marks Are Actually Allocated: An Example
For a typical secondary school essay in a Hong Kong DSE-style marking scheme, a 15-mark essay might be allocated something like:
- Content: 7 marks
- Language: 8 marks
For a PSLE Singapore-style composition:
- Content and language marks are combined under a holistic descriptor, but language errors move the piece down through descriptor bands
For Cambridge IGCSE First Language English:
- Reading and writing skills are assessed separately; writing is marked on Content/Organisation and on Language
The specifics vary, but in nearly all cases grammar errors directly affect the language component of the mark, and a high rate of errors will push a student out of the top descriptor bands even if their ideas are good.
What This Means Practically
For students: focus your revision on the error types you make most frequently, not on learning impressive vocabulary. Consistent tense, correct subject-verb agreement, and accurate spelling will move your grade more reliably than adding “moreover” or “nevertheless” to your vocabulary.
For parents: the most valuable thing you can do is help your child track which grammar errors recur across multiple essays. Three or four sessions of focused review — identifying the pattern, understanding the rule, looking for it specifically in the next essay — will produce visible improvement in the language mark.
Teachers notice and reward students who are clearly working to address their weaknesses. A student who consistently removes their most common error type from their writing is demonstrating exactly the kind of self-awareness and effort that good marks reflect.
Frequently Asked Questions
Should my child aim for a formal or informal tone in secondary school essays?
It depends on the task. Opinion essays, reports, and formal letters should use a formal register. Personal narratives and descriptive essays may use a more natural, personal voice. The key is consistency within a piece — mixing formal and informal registers within the same essay is a common error that teachers notice immediately.
Does essay length matter?
Yes, within the expected range. An essay that’s clearly too short signals that the student ran out of ideas or didn’t develop their points sufficiently — this affects both the content and organisation marks. An essay that’s significantly longer than required sometimes works against the student if it includes repetition, digression, or padding. Aim to meet the expected word count range with fully developed content, not filler.
My child has good ideas but poor grammar. Which matters more?
Both matter, but poor grammar affects the language mark directly and also affects how the examiner receives the ideas. A high-content, low-accuracy essay will typically sit in the middle descriptor band. Improving grammar to a consistent level without losing the strength of ideas is the most effective path to the top band.
Is it better to write simple, correct sentences or complex, potentially incorrect ones?
Simple and correct beats complex and incorrect almost every time at secondary level. Short sentences with accurate grammar score better than long sentences full of errors. Once grammar is solid, complexity can be introduced gradually and purposefully.
How can my child improve their essay organisation quickly?
The fastest method: before writing, spend three to five minutes on a brief outline. Write down the topic of each paragraph in one sentence. Check that the sequence is logical and that each paragraph is a separate idea. Students who plan even briefly write significantly more organised essays than students who write without any pre-planning.
