NSW Check-in Assessment common mistakes
NSW Check-in Assessment · Understand the traps and how to avoid them.
Choosing an answer option that matches a word or phrase seen in the passage rather than the option that answers the question actually asked.
Under time pressure, students pattern-match surface words instead of re-reading the question stem and checking what it requires (e.g., 'the main purpose' versus 'one detail mentioned').
What to do instead
Before reading the options, restate the question in the student's own words and underline the key instruction word (main idea, purpose, best evidence). Then eliminate any option that only echoes passage wording without addressing that instruction.
Answering inference questions with a statement the text states directly, or with a personal opinion the text does not support.
Students conflate 'what the text says' with 'what the text implies', and often lack a habit of locating the evidence line before choosing.
What to do instead
Practise a two-step routine: find the sentence(s) that support each candidate answer, then ask 'does the text say this outright, or does it only let me conclude it?' Only the second counts as an inference, and the support must be locatable.
Misreading negation, qualification, and scope words such as 'not', 'except', 'least', 'only', and 'mainly'.
These small words reverse or narrow the task, and fast readers skim over them because they carry little semantic weight in isolation.
What to do instead
Circle or highlight every negation and qualifier in the question stem before evaluating options. For 'EXCEPT' and 'NOT' questions, rewrite the task positively (e.g., 'three of these are true; find the false one') before starting.
Writing a response that retells the source text or lists features of the language without explaining effect or linking to the question focus.
Students default to summary because it feels safe, and they have not internalised that analysis questions reward explanation of how and why, not description of what.
What to do instead
Use a fixed paragraph frame: claim, evidence (brief quotation or reference), explanation of effect on the reader or on meaning. Draft the explanation sentence first and check it answers 'so what?' before adding evidence.
Running out of time because the student reads every passage at the same pace and spends too long on early items.
No timing plan and reluctance to leave a hard item means later, often easier, questions are never attempted.
What to do instead
Set a per-section time budget, mark any item unresolved after roughly a minute, and move on. Reserve the final minutes to return to flagged items; practise with a visible timer until the pacing habit is automatic.
Choosing a distractor that is arithmetically plausible but ignores the units, the question's rounding instruction, or the real-world context of the problem.
Students compute with the numbers they see and stop at the first numerical match, without checking whether the answer is sensible in the situation described.
What to do instead
After computing, run a two-question check: 'what units should this be?' and 'is this a sensible size for this situation?' Write the unit next to the working before selecting an option.
Making a place-value or decimal-alignment error when adding, subtracting, or comparing decimals, such as lining up the last digits instead of the decimal points.
The column method learned with whole numbers is applied mechanically, and trailing zeros are omitted so the numbers look shorter than they are.
What to do instead
Pad all decimals to the same number of places with trailing zeros, then align decimal points vertically before operating. Estimate the answer first so a misplaced decimal is immediately visible.
Applying an operation to the wrong quantity in multi-step problems, for example finding a percentage of the original price when the question asks for the discount, or reversing a ratio.
Students grab the first procedure that the numbers suggest rather than mapping each quantity in the problem to a role (whole, part, rate, difference).
What to do instead
Before calculating, annotate the problem by labelling each given number with its role and writing a one-line plan of the steps in order. Check the plan against the final question sentence before computing.
Giving a numerical answer with no working, so method marks are lost and errors cannot be self-corrected.
Students believe working is only needed when the answer is uncertain, and they underestimate how much partial credit rewards visible steps.
What to do instead
Make showing each step a non-negotiable routine, including the substituted formula and intermediate values. During review, cover the answer and follow the written working to see whether it alone justifies the result.
Misreading tables, graphs, and diagrams by using the wrong axis, scale, or legend, or by reading a value from the gridline rather than between gridlines.
Visual displays invite a quick glance, and students do not check axis labels, units, or the increments between marked values.
What to do instead
Before reading any data, state aloud the label and unit of each axis, the scale increment, and what the legend symbols mean. Then locate the required value by tracing from both axes and estimate between gridlines explicitly.
