Many teachers across Papua New Guinea are worried that overcrowded classrooms are restricting students' learning.
While the government's free education policy has boosted enrolment numbers and school attendance rates, some schools are struggling to accommodate the influx of students.
One Port Moresby primary school principal, who asked not to be named, is glad more students are attending school but she says overcrowding is taking its toll.
"The teachers are having a difficult time in teaching the class. I don't think effective teaching is taking place because the students are just too many for the teachers to teach them. But my teachers are trying their very best but at the end of the day I see that my teachers are exhausted."
She says the capital's education authorities have promised more classrooms and teachers, but not until next year, despite the region's schools desperately need them now.
