PISA is an age-based survey, assessing 15-year-old students in school at grade seven or higher. The PISA research intends to provide the comparative educational efficiency across countries and so as to define the civil literacy. In order to examine school factors how to effect education outcomes, PISA mainly focus on students’ social-economical background indicators which variables are explainable. Those relative variances include school types (public or private), school location (urban or rural), and student immigration status and so on, through international comparable analysis to reveal the reality of education quality and equity.
In order to examine the correlation between school environment and student performance, PISA takes school characteristics and accountability into account as well. The school input is also a factor of student performance. Learning motivation, learning strategic and self-confidence of students plus family and school input are cross interacting.
