The qualifications authority says it is advancing with the use of AI for examination of exams, while raising questions about its misuse by school students.
Appearing before the Education and Workforce Selection Committee for its annual review on Wednesday, NZQA officials told MPs that Artificial Intelligence created risks to the integrity of internal evaluation, but 80% of NCEA credits last year came from internal evaluated work.
The chief executive of the authority, Grant Klinkum, told the deputies that he was providing data to inform the government’s work on the qualification of NCEA.
He said that an example of this data was the fact that last year 80% of the NCEA credits reached were through internal evaluation and 20% were through external evaluations.
“Now, if you think about the risks of AI -generated in the internal context, you can expect a different balance between internal and external, because one reason for external evaluation is that it helps triangular the results that are achieved internally,” he said.
“AI is clearly a challenge for the educational system in general and, of course, a huge opportunity, but as it is a challenge that would lead it, it is 20% of the end results of sufficient external ones in the current environment.”
Klinkum said the NZQA was using the automated test score.
“In May this year, for the first time we will use the automated test score for the essay assessments that are administered to the year 10,” he said.
“Indeed, this is the one making the first marking scan.”
Klinkum said the decision followed an automated work marking trial of 36,000 students who found a contract rate of 80% – the same as if humans made the marking.
He said the automated test score would make the first round of marking on May writing tests.
“We will mark 40% on both sides of the border between the passage and fail through human marking, so that at least 20,000 items of ATS marked material are marked by humans to ensure that someone at some points of the limit is not harmed.
“And of course, human marking will prevail if there is any difference of opinion,” Klinkum said.
He said the change would allow NZQA to return results to students faster.
“This allows us to return these assessments to schools and students earlier so that they have the opportunity to prepare for the next evaluation a few months later if they have failed to evaluate the writing for the first time,” he said.
RNZ reported last year that some schools were changing the way students evaluated the threat of AI cheating.
