The Nauru government is extending the school day to raise achievement levels.
Nauru's primary and secondary students currently don't have classes in the afternoon meaning they spend one and a half hours less in the classroom than the Pacific average.
An education advisor, Joanna Crawford-Bryde, says the impact of this is reflected in poor results in national examinations and limited achievement compared with other areas.
"And you can fairly confidently draw a direct correlation between the limited hours we are having of schooling at the moment, so students currently compared to other places around the Pacific, we have approximately 20 percent less [time] per day, so for example, in ten years of schooling students in Nauru would actually only be getting eight years compared to students elsewhere."
Nauru's education advisor, Joanna Crawford-Bryde, says the longer hours will allow teachers to explore the curriculum in greater depth.
Schools will now teach through to 3pm each day.
