NAPLAN online adaptive testing: why each child sees different questions
NAPLAN reading, conventions of language and numeracy are tailored: the questions your child sees depend on how they answer earlier ones. A harder set is not a bad sign, and results account for question difficulty.
Last checked against the official sources.
In tailored tests, the questions your child sees depend on how they answer. Results use both how many questions were correct and how hard they were, so seeing harder questions does not mean your child did badly.
How it works
ACARA describes a branching design. Each student at a year level starts with a similar set of questions, called testlet A. Their answers decide the next testlet, which may be less complex (B) or more complex (D). The same idea applies again at the next stage.
The NAP page says reading, numeracy and conventions of language are all tailored. Reading and numeracy follow the testlet pattern above. Conventions of language has a spelling section and a grammar and punctuation section, each with 2 branching points.
How results are calculated
ACARA says a result is based on both the number of questions answered correctly and the average difficulty of the questions assigned. Its page adds that a student who completes a more complex set is more likely to achieve a higher scale score.
That is why two children can answer the same number of questions correctly and receive different scale scores.
What ACARA says it is for
ACARA says tailored testing measures achievement more precisely across a wider range of abilities. Students who struggle early are given questions better suited to their level, which helps them keep their confidence, while strong students receive more complex questions to keep them engaged.
If your child comes home saying the test was hard, or easy, you do not need to read much into it. The test is designed to adjust. Quote ACARA to them if it helps: they should not be concerned if they find questions challenging.
Familiarity with the format
The demonstration site is not tailored, but it includes example branching messages so children can see what happens. In conventions of language, students cannot return to the spelling section once they move on to grammar and punctuation.
What this means for practice
Each student answers a set number of questions in each test, about the same as the old paper tests, but which questions they see depends on how they answer. For that reason a question-count target is not a useful way to practise.
ACARA says students are not expected to study, so any practice is optional. If you want some, keep it light. ExamExplained is run alongside a tutoring business, and its free NAPLAN practice is original, not official, and not endorsed by ACARA.
