The document provides amended marking instructions for the 2016 National 5 History exam in Scotland. It outlines general marking principles, such as always marking responses positively and how many marks are awarded for different levels of response. It also provides specific guidance on how to mark different question types, such as describing events, explaining reasons, making judgements, evaluating sources, comparing sources, and assessing how fully a source describes an event. Markers are instructed to code candidate responses to indicate which aspects are being credited. All marking must be done according to these principles and instructions.
