A model system of assessment of NGSS for California

The model system of assessments was designed to satisfy multiple goals: 

  • to support the vision of teaching and learning with NGSS laid out in the K-12 Science Framework;
  • to facilitate the teaching and learning of science at all levels in K-12;
  • to address all three dimensions of the performance expectations of NGSS;
  • to provide data on performance at the student, class, school, district and state level; and
  • to fulfill federally mandated requirements while prioritizing the preceding goals.
