SATS papers - Science 2009 Marking Scheme

The Science 2009 Marking Scheme for the SATs (Standard Assessment Tests) provides a detailed framework for assessing students' responses in the levels 3–5 tests A and B. The Qualifications and Curriculum Authority, which is an exempt charity, first published this marking scheme in 2009 and holds the copyright. The scheme is designed to ensure consistency and accuracy in marking by external markers hired by external marking agencies under contract to the QCA. The mark schemes are structured in tabular form, indicating the number of marks available, the requirements for awarding marks, examples of creditworthy responses, and additional guidance for markers. This comprehensive approach ensures that scientifically correct answers are recognized, while also allowing for alternative expressions of correct scientific understanding.

The marking scheme stipulates that for questions requiring a description of the relationship between two continuous variables, a general comparison or a pair of specific comparisons will be credited accordingly. The booklet also provides guidance on applying the mark schemes, emphasizing the use of professional judgement by external markers in cases of alternative wording or diagrammatic responses. The level threshold tables, which determine the grade boundaries, were made available on the National Assessment Agency's website later in the year. This marking scheme is a crucial tool in maintaining the integrity and standardization of the assessment process, ensuring that students' knowledge and understanding of science are evaluated fairly and accurately.
