Interpretation deals with logic, analysis, and reasoning. The Ideas strand within Argument is comprehensive and evaluates the synthesis of ideas. The interpretation strand is much more specific to the paragraph level.
Analysis evaluates the discussion of evidence. At the lower level, is the interpretation accurate and focused? At higher level, students are expected to analyze thoughtfully, including subtle nuances while retaining clarity.
Justification evaluates a student’s ability to develop a link from evidence to assertion. As readers and teachers, we often find that students almost prove their argument but fail to fully land on their point: this criterion addresses that logic gap.
