In term 3, 2012, 22 teacher-assessors collected data from 5,000 children in 200 schools around the country. The information they collected will inform the education community in New Zealand about how our learners are achieving in science and writing. This endeavour marks the beginning of a new national monitoring study of primary student achievement in English-medium schools in New Zealand. The National Monitoring Study of Student Achievement: Wānangatia Te Putanga Tauira (NMSSA) is a programme to assess and understand student achievement across the curriculum at the primary level in New Zealand. It replaces the National Education Monitoring Project, well known to teachers as NEMP, which operated between 1995 and 2010.
