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

• Uses nested selection statements. (Algorithmic Thinking)
• Appreciates the need for, and writes, custom functions including use of parameters. (Algorithmic Thinking) (Abstraction)
• Knows the difference between, and uses appropriately, procedures and functions (Algorithmic Thinking) (Abstraction)
• Understands and uses negation with operators. (Algorithmic Thinking)
• Uses and manipulates one dimensional data structures. (Abstraction)
• Detects and corrects syntactical errors. (Algorithmic Thinking)
