These regions are: Northern, Waikato/Bay of Plenty, Central, Southern, and Te Uepū ā-Motu (ERO's Māori review services unit).

[3] In May 2023, the Independent Children's Monitor was transferred from the Ministry of Social Development, and reconstituted as a departmental agency of the Education Review Office.

Reviews are carried out every three years on average, but are more frequent where the performance of a school or service is below standard or there are risks to the education or safety of the students or children.

In some cases of poor performance or major risks to students, the department may recommend to the Minister and Secretary of Education some form of intervention to the school's management.

The department recommended that the Ministry of Education shift its focus from its Early Attendance Service programmes to preventing children from missing out from schools.
