NCEA and New Zealand Scholarship exams begin today for about 140,000 students and this year, about 8000 of them will be sitting NCEA exams online.
Students have been preparing for 120 exam sessions this year, says New Zealand Qualifications Authority deputy chief executive Kristine Kilkelly.
"Our recent evaluation shows that nearly all survey responses from students, who have taken part in a digital exam, preferred an online exam rather than written exams," Ms Kilkelly said.
"This is reflected in participation in this year's NCEA exams online, with a 60 per cent increase in participation compared to 2017."
Since 2014, almost three quarters of New Zealand secondary schools and around 30,000 students have experienced at least one digital examination, Ms Kilkelly said.
Fifty-two schools are planning to participate in Digital Pilot examinations in 2018, which are available at NCEA Levels 1-3 in English, Media Studies and Classical Studies, she said.
NZQA aims to have NCEA examinations available online for 14 subjects at Levels 1-3 in 2019.
The range of subjects will be further expanded in 2020 and beyond, the authority says.
