Assessment Objectives Explained

Edexcel GCSE Mathematics tests three Assessment Objectives (AOs). Understanding what each AO demands — and how marks are distributed — helps you know exactly what examiners want to see.

The Three Assessment Objectives

AO	Description	Approximate Weighting
AO1	Use and apply standard techniques	~40%
AO2	Reason, interpret and communicate mathematically	~30%
AO3	Solve problems within mathematics and in other contexts	~30%

These weightings apply across all three papers combined.

AO1: Use and Apply Standard Techniques (~40%)

AO1 is the most heavily weighted objective. It tests whether you can perform mathematical procedures accurately and efficiently.

What AO1 Looks Like

AO1 questions require you to:

• Recall facts, terminology and definitions.
• Use and interpret mathematical notation correctly.
• Carry out routine calculations and procedures accurately.
• Use mathematical instruments (ruler, protractor, compasses) with precision.

Example AO1 Questions

Example 1: Simplify 4x³ × 3x². Answer: 12x⁵ (1 mark)
