Science literacy achievement: senior secondary schooling

Table 1: Distribution of PISA Science Literacy Scores for New Zealand (2006, 2009, 2012 and 2015)
Notes:
  1. The scientific literacy domain has undergone considerable expansion and change since being a minor domain in PISA 2000 and PISA 2003, it is not therefore possible to compare science outcomes from PISA 2006 onwards with these earlier PISA assessments.
  2. Figures may differ slightly to those reported elsewhere due to rounding.

Notes:
  1. This table presents percentages based on total response ethnicity. Total response ethnicity is when people who have been identified in more than one ethnic group have been counted in each ethnic group.
  2. Figures may differ slightly to those reported elsewhere due to rounding.
