The Computing Progression Pathways suggests that at the black level, on the theme of programming & development, a student should demonstrate that he/she:

• Appreciates the effect of the scope of a variable e.g. a local variable can’t be accessed from outside its function. (Abstraction) (Algorithmic Thinking)
• Understands and applies parameter passing. (Abstraction) (Generalisation) (Decomposition)
• Understands the difference between, and uses, both pre-tested e.g. ‘while’, and post-tested e.g. ‘until’ loops. (Algorithmic Thinking)
• Applies a modular approach to error detection and correction. (Abstraction) (Generalisation) (Decomposition)
