This document discusses assessment in education. It emphasizes that assessment, curriculum, and teaching should be aligned with overall learning goals. When these are aligned, it is a strong predictor of student achievement in math and science. Formative and summative assessments both have important roles to play - formative to help students develop independent learning skills and self-reflect, summative to check progress. Assessments should be deliberately designed to improve learning rather than just audit performance, and must be valid, reliable, and consistent with their intended purpose. Effective assessment is ongoing to provide frequent feedback opportunities for students.
