Curlewis Public School students has shown that sometimes old school is better, completing their NAPLAN testing using pen and paper rather than the recently troublesome digital way.
The school's principal Jacqui Jones said they could have used the Internet to complete the testing but had chosen not to.
That turned out to be a lucky thing, when thousands of students nationwide were affected by technical glitches with NAPLAN Online on Tuesday, leaving teachers, students and parents upset.
"We had the option, but our Internet is quite intermittent," Ms Jones said.
"Our kids would be quite capable [of using the Internet to complete the tests], but our Internet needs to be improved."
Five students in Year 3 and 10 in Year 5 completed their NAPLAN tests at the school, and Ms Jones said they all "went really well".
About 170 students at St Mary's College did take the Year 7 and Year 9 NAPLAN tests online, but principal Max Quirk said they had "very limited problems".
"[NAPLAN Online] dropped out for two to three minutes and then carried on ... but whatever time was lost, students got back at the end," Mr Quirk said.
"We had practice sessions beforehand, so the system could cope with it and so students and staff were familiar with it."
Gunnedah South Public School reported no glitches at all. NAPLAN students were even treated to a barbecue breakfast every morning of the three days of tests.
"[Students] were really positive - they had a really nice start to the day and enjoyed the breakfast the school staff cooked for them," Gunnedah South Public School principal Peter Baum said.
The Australian Curriculum, Assessment and Reporting Authority (ACARA), which manages NAPLAN testing nationwide, said in a statement it would continue "to investigate the cause of connectivity issues experienced by some schools".
"Another 400,000 online tests were successfully submitted [on Wednesday]," the statement said.
"Overall feedback is that online testing has proceeded smoothly, with few connectivity issues experienced."
ACARA said "any inconvenience to schools and students during testing is regretted".
"If technical issues are experienced in the coming days, there are procedures in place to manage them and ensure that all students are able to take the tests.
"The technology and logistics of a national online project of this size are highly complex ... and the co-operation and assistance of all involved is appreciated."
