The assessment criteria shown below have been developed to provide a broader range of assessment opportunities for students of all abilities. Each national curriculum statement has been broken down into three distinct levels from bronze (A) to silver (B) to gold ©. Individual student performance can be recorded, providing a map of progress across the whole curriculum. Students can use this mapping to independently identify how they are progressing and this data can also be shared with parents.

This is the first lesson in a series teaching Python Programming. It really starts at the very beginning. It’s designed to be used by children and adults with no experience of programming. Python and the Python Logo are trademarks or registered trade marks of the Python Software Foundation.
