The Ministry of Education is rolling out software to store children's details, including achievement levels.
The PaCT program would allow teachers to monitor students' academic success from Years 1-11.
A ministry spokesperson said it had not been decided if the database would be mandatory for all schools.
Hora Hora School principal Pat Newman said he had absolutely no confidence in the ministry's ability to oversee the development of new software, especially after the problems caused by Novopay.
"The Ministry of Education, who currently can't even pay teachers, is now proposing to take every child's data using another new computer programme."
