The writing test is not about handwriting skills and NAPLAN Online is not about keyboarding skills. There are variations in how fast and well a student can type, just as there are variations in how fast and well a student can write by hand.
ACARA research shows that online writing is similar to handwriting in terms of the quality of writing produced by students at each year level. It also shows that students generally appreciate the use of online features such as editing tools (noting that online features such as grammar and spell-check are disabled during NAPLAN testing).
Students do not have to be able to touch type to successfully complete the test.
