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

• Understands that iteration is the repetition of a process such as a loop. (Algorithmic Thinking)
• Recognises that different algorithms exist for the same problem. (Algorithmic Thinking)(Generalisation)
• Represents solutions using a structured notation. (Algorithmic Thinking) (Abstraction)
• Can identify similarities and differences in situations and can use these to solve problems (pattern recognition). (Algorithmic Thinking)(Generalisation)

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.
