Online NAPLAN testing will continue on Wednesday despite thousands of students across hundreds of WA schools struggling to complete their assessments due to a technical issue.

Schools had been encouraged to complete the national standards testing online, with 50 per cent of facilities choosing to do so, compared to just 15 per cent the previous year.

Thousands of students struggled to complete the first day of NAPLAN testing online.

The large number of children logging in to complete assessments caused country-wide glitches, with thousands of students being repeatedly logged out, or having work deleted.

Radio 6PR Perth Live presenter Oliver Peterson spoke to a number of students about the glitches.
