Students who are sick cannot complete NAPLAN at home. Students who are absent on the day of testing may be able to complete catch-up tests if they return to school within the NAPLAN test window. If a student is unable to attend school, they will be counted as absent and will not receive NAPLAN results for any tests they are absent for.
There are comprehensive NAPLAN test administration and security procedures that need to be followed for NAPLAN assessments, and the tests are overseen by teachers to ensure results are comparable. It is not practical to administer a secure test in a home environment in the event that a student is ill.
