"If successful, it will pave the way for online exams in the future."
The NZQA website states the pilot was "part of NZQA's digital transformation journey" and an ongoing investigation of computer-based methods of assessment.
The 2015 pilot was a revamped version of the test built on results from a 2014 trial, and was achieved in conjunction with Dunedin-based digital resource Education Perfect.
Student and teacher feedback on the 2014 trials yielded digital tests tailored for the screen this year, including working space visible alongside the question, time for students to familiarise themselves with the online exam, and touch screens and styli that aped paper and pen "being the medium used on a daily basis for solving mathematical problems".
Teachers also last year found marking "cumbersome" due to the randomisation of questions, which were vital to the system and would remain.
"While this will be the second computer-based pilot, it will be the first on such a scale - approximately 13,000 students from 146 schools have registered to participate and we have a good range of school types and deciles involved," the NZQA website states.
The pilot also broke ground as the first time emCAT results would count for Level 1 NCEA.
