This document discusses effective use of learning objectives and success criteria when planning lessons. It defines learning objectives as what students will learn and success criteria as how students will demonstrate their learning. It provides tips for writing clear, specific objectives and criteria, such as separating the learning from the context, using verbs that describe the learning rather than just the task, and avoiding simply repeating the objective in the criteria. The document also discusses common pitfalls to avoid and gives examples of well-written objectives and criteria for both literacy and maths lessons.
