The document discusses shifting assessments to higher levels of depth of knowledge (DOK). It explains that Common Core State Tests (CST) only assessed levels 1-2, which involve recall and basic skills. In contrast, Smarter Balanced Assessments (SBAC) will assess levels 1-2 as well as higher levels 3-4, which involve strategic thinking, rationalization, and reasoning across multiple steps. Examples are provided for mathematics questions at each DOK level to illustrate the increasing complexity of thinking required. The document emphasizes that developing skills at all DOK levels is important for students.
