Mr McAllen said many of the teachers brought along samples of their marking.
"They might bring along something that was especially tricky to mark, or something that was on the borderline between merit and excellent, for example. They can get feedback from other teachers on their marking."
Mr McAllen said the moderation meetings were valuable for all teachers, but particularly for those from smaller schools, where there may be only one or two teachers for a subject.
"It also helps to build those connections between the different schools," he said.
This is the second moderation meeting among Whanganui secondary schools this year. There was one held in term two at Wanganui Collegiate School.
The schools represented at the meetings were Whanganui High School, Wanganui Collegiate, Whanganui Girls College, Whanganui City College, Cullinane College, Rangitikei College, Nga Tawa Diocesan School, Patea Area School and Ruapehu College.
Subject areas included digital technology, English, ESOL, languages, learning support, mathematics, materials technologies, performing arts, physical education and health, sciences, social sciences, te reo and visual art.
