The document discusses establishing a guaranteed and viable curriculum through teacher collaboration. It emphasizes that the fundamental purpose of schools should be student learning. Key steps include: 1. Teachers work in teams to identify essential learnings and "power standards" from state standards. 2. Teams ensure every student learns these standards through developing common formative assessments and ensuring consistent curriculum pacing. 3. Data from common assessments is used to inform instruction and provide timely support for students who are not learning or have already mastered the material. The overall goal is establishing curriculum, instruction, and assessments aligned to prioritize what is most essential for students to learn.
