A majority of voters want information on schools' achievement in national standards to be released publicly for comparison, a Herald-DigiPoll survey shows.
But a sizeable minority oppose its release.
The poll coincides with the primary teachers' union, the New Zealand Educational Institute, advising schools to refuse requests under the Official Information Act to divulge achievement information.
Schools have sent national standards information to the Ministry of Education and it is due to be published for the first time in September.
League tables for secondary schools' NCEA results are commonly published but not for primary schools.
