NAPLAN online enables the use of tailored testing, instead of a static approach tailored tests give students questions that are better suited to their ability, resulting in better assessment and more precise results. Trials by ACARA show that students are more engaged with tailored tests.

In NAPLAN online, students attempt the same number of questions in the same amount of time as in paper NAPLAN. Based on their responses, tailored testing provides questions more aligned to individual ability, providing teachers with more detailed information about what each student can do, rather than what they cannot do.

The ACARA website provides information that explains what tailored testing is, and research supporting its use in NAPLAN online.
