3 Assessment To gain the award of the Course, the learner must pass all the Units as well as the Course assessment. Course assessment will provide the basis for grading attainment in the Course award. Course assessment SQA will produce and give instructions for the production and conduct of Course assessments based on the information provided in this document. Added value The purpose of the Course assessment is to assess added value of the Course as well as confirming attainment in the Course and providing a grade. The added value for the Course will address the key purposes and aims of the Course, as defined in the Course Rationale. It will do this by addressing one or more of breadth, challenge or application. In this Course assessment, added value will focus on the following: breadth drawing on knowledge and skills from across the Course challenge requiring greater depth or etension of knowledge and skills application requiring application of knowledge and skills in practical or theoretical contets as appropriate This added value consists of: using mathematical reasoning skills to think logically, provide justification and solve problems using a range of comple concepts selecting and applying comple operational skills using reasoning skills to interpret information and to use comple mathematical models effectively communicating solutions in a variety of mathematical contets eplaining and justifying concepts through the idea of rigorous proof thinking creatively To achieve success in the Course, learners must show that they can apply knowledge and skills acquired across the Course to unseen situations. The question paper requires learners to demonstrate aspects of breadth, challenge and application in mathematical contets. The use of a calculator will be permitted. April 013 version 1.0 3

4 Grading Course assessment will provide the basis for grading attainment in the Course award. The Course assessment is graded A D. The grade is determined on the basis of the total mark for the Course assessment. A learner s overall grade will be determined by their performance across the Course assessment. Grade description for C For the award of Grade C, learners will have demonstrated successful performance in all of the Units of the Course. In the Course assessment, learners will typically have demonstrated successful performance in relation to the mandatory skills, knowledge and understanding for the Course. Grade description for A For the award of Grade A, learners will have demonstrated successful performance in all of the Units of the Course. In the Course assessment, learners will typically have demonstrated a consistently high level of performance in relation to the mandatory skills, knowledge and understanding for the Course. Credit To take account of the etended range of learning and teaching approaches, remediation, consolidation of learning and intration needed for preparation for eternal assessment, si SCQF credit points are available in Courses at National 5 and Higher, and eight SCQF credit points in Courses at Advanced Higher. These points will be awarded when a Grade D or better is achieved. April 013 version 1.0 4

5 Structure and coverage of the Course assessment The Course assessment will consist of one Component: a question paper. Component 1 question paper The purpose of the question paper is to assess mathematical skills. A calculator may be used. The question paper will sample the skills, knowledge and understanding that are contained in the Further mandatory information on Course coverage section at the end of this Course Assessment Specification. The question paper will consist of a series of short and etended response questions (some of which may be set in contets) that require the application of skills developed in the Course. Learners will be epected to communicate responses clearly and to justify solutions. The paper will have 100 marks. April 013 version 1.0 5

6 Setting, conducting and marking of assessment Question paper The question paper will be set and marked by SQA and conducted in centres under conditions specified for eternal eaminations by SQA. Learners will complete this in 3 hours. April 013 version 1.0 6
