This assessment test allows you to assess your pupils against the national curriculum specification for Python programming. It should be used at the end of Key Stage 3 as a summative assessment rather than as a formative assessment. The national curriculum specifies that by the end of Key stage 3 pupils should have been taught to “use two or more programming languages, at least one of which is textual, to solve a variety of computational problems; make appropriate use of data structures (for example, lists, tables or arrays); design and develop modular programs that use procedures or functions (for example, sub programs).” This test allows you to assess if your pupils have met this criteria. It includes a 6 page PDF document which should be printed and given to your pupils to complete under test conditions. There is no practical element to this test and is completed through a written test. This resource also includes a mark scheme to aid the teacher in marking the paper and even includes grade boundaries and descriptions that can assist the teacher when writing pupils’ long reports.
