For Cambridge International A Levels, they describe performance at three levels – grades ‘E’, ‘C’ and ‘A’.  \nGrade descriptions sit alongside other key documents that illustrate examination standards, including:  \n• the syllabus, which presents what students should be taught over a course of study and explains how this is assessed  \n• the specimen assessment materials, which illustrate the structure of the assessment and the kinds of tasks that candidates complete  \n• grade thresholds, which show the total mark required to achieve a grade. Grade descriptions are produced with a wide range of audiences in mind. For teachers, they support lesson planning and curriculum development, while students may gain useful insights into what is required to achieve a high grade and what candidate performance at lower grades typically looks like. For university admissions staff and employers, and those less familiar with Cambridge, they paint a picture of typical performance at different grades. Cambridge publishes grade descriptions for a qualification once examinations have taken place for the first time and we review them when a qualification is  \nsubstantially revised. They are developed by highly experienced examiners who understand performance standards in the subject area and have studied samples of candidate work.  \nHow do I use this resource?  \nGrade descriptions are presented as a grid, with content areas at the start of each row and the different grades at the top of each column. The content areas group together various aspects of the syllabus – they reflect topics, assessment objectives, key concepts, syllabus aims and/or components. The way they are organised is specific to each subject. For each content area there is a descriptor for each grade. Reading across the row from left to right, the descriptors represent increasing  \nlevels of performance, with each grade descriptor building on, and including, the last.  \nEach column represents overall performance at a particular grade. Reading down the column from top to bottom, the descriptors capture the range of knowledge, understanding and skills that a candidate comfortably achieving the grade is likely to demonstrate.  \nWhere content areas for the first and second halves of the A Level are distinct, they are also assessed a different standards. Performance for content areas assessed at AS Level is therefore described separately in this document.  \nCambridge produces grade descriptions to support teaching and learning and the interpretation of candidate scores and grades. We do not use them to set grade thresholds. As such, they cannot be used to challenge the grade awarded to any individual candidate.  \nGrade Descriptions  \n\n| Area of knowledge,\u003Cbr>understanding and skills | Typical performance at grade E | Typical performance at grade C | Typical performance at grade A |\n| --- | --- | --- | --- |\n|  |  |  |  |\n| Basic principles of computer science | Key areas of knowledge: • Defining data types and storing data, file handling\u003Cbr>• Communication protocols\u003Cbr>• Types of processor, virtual machines and Boolean algebra\u003Cbr>• How operating systems and translators work\u003Cbr>Topics assessed at • Digital storage and compression of data, including numerical, text, image and sound\u003Cbr>AS Level standard: • Computer networks, including the transmission of data and the use of IP addresses\u003Cbr>• Computer hardware, including construction of logic circuits and use of sensors for monitoring and control\u003Cbr>• Computer architecture and the use of assembly language\u003Cbr>• System software, including operating systems, language translators and the use of an Integrated Development Environment (IDE) |  |  |\n|  | • Stude","cbCaipOrTEytGdrn","https://ap.wps.com/l/cbCaipOrTEytGdrn","pdf",192015,"English","# What are Grade Descriptions?\n## How do I use this resource?\n# Grade Descriptions\n## Basic principles of computer science\n## Data security, data management and use of AI","[{\"question\":\"What are grade descriptions used for in Cambridge International A Levels?\",\"answer\":\"They describe the level of performance typically demonstrated by candidates achieving different awarded grades.
