Filling in the A in the GAISE Framework with Assessments for Statistics in the Common Core State Standards

LOCUS is an NSF Funded DRK12 (DRL-1118168) project focused on developing assessments of statistical understanding. These assessments measure students’ understanding across levels of development as identified in the Guidelines for Assessment and Instruction in Statistics Education (GAISE) Report: A Pre-K-12 Curriculum Framework. LOCUS assessments measure statistical understanding at two levels: Beginning/Intermediate and Intermediate/Advanced. The intent of these assessments is to provide teachers, educational leaders, assessment specialists, and researchers with a valid and reliable assessment of conceptual understanding in statistics consistent with the Common Core State Standards (CCSS).

All Versions of the LOCUS Assessments Focus on the Practice and Process of Statistical Problem Solving

  • Formulating Statistical Questions (10-15% on Beg/Int; 15-20% on Int/Adv)
  • Collecting Data (25-30% on Beg/Int; 20-25% on Int/Adv)
  • Analyzing Data (30-35% on Beg/Int; 25-30% on Int/Adv)
  • Interpreting Results (25-30% on Beg/Int; 30-35% on Int/Adv)

LOCUS assessments have been administered to the following populations of test takers: students in grades 6-12 (including AP Statistics), students in introductory statistics, preservice teachers, and inservice teachers.
