ACARA has developed a tailored test design, which could be applied to NAPLAN online. The 'tailored test' is a multistage, branching test design that delivers different sets of questions ('testlets') to students depending on their achievement on previous questions. Online delivery of assessments allows the use of a tailored test design to better match questions to an individual student's ability in a way that is not feasible for paper-based testing.The tailored test design for reading and numeracy was developed and trialled in schools in 2013. Reading and numeracy tests had a number of testlets. Each testlet was developed as a mini-test. Each student completed three testlets.
The diagram and discussion below illustrate a proposal for the potential paths that students may take through NAPLAN online reading and numeracy tests:
- Tailored tests provide a more precise measurement of student performance. This design allows for greater differentiation of students by using a wider range of question difficulty, without adding to the length of the test for each individual student.
- Trials of the tailored test design suggest that students are more engaged with tests that adapt to their achievement. Students who struggle with the initial set of questions are given questions that are more suited to their ability, so that students are less likely to become discouraged as they progress through the tests. High-achieving students are given questions that better challenge their abilities.
- The tailored test design has the potential to reduce anxiety in students who may find the current paper-based format of NAPLAN too challenging.
- While each student will still answer the same number of questions as for the paper tests, the number of items in the whole test is larger. As a result, a wider range of aspects of the curriculum can be tested across the NAPLAN cohort.
