The Computing Progression Pathways suggests that at the red level, on the theme of algorithms, a student should demonstrate that he/she:

• Understands a recursive solution to a problem repeatedly applies the same solution to smaller instances of the problem. (Algorithmic Thinking) (Generalisation)
• Recognises that some problems share the same characteristics and use the same algorithm to solve both.(Algorithmic Thinking)(Generalisation)
• Understands the notion of performance for algorithms and appreciates that some algorithms have different performance characteristics for the same task. (Algorithmic Thinking) (Evaluation)

It is suggested that:

• Primary teachers focus on the badge statements from the Pink to Purple row.
• Secondary teachers focus on the badge statements from the Purple to Black row.
• The white row overlaps with the KS4 qualification specifications.
