KeyMaths3UK gives you the tools to assess maths skills of students aged 6 years to 16 years 11 months and assist in intervention planning  

  • KeyMaths3UK is a comprehensive, norm-referenced measure of essential mathematical concepts and skills.
  • KeyMaths3UK is untimed and individually administered.  

KeyMaths3UK content presents the full spectrum of maths concepts and skills in three areas: Basic concepts (conceptual knowledge), Operations (computational skills) and Applications (problem solving). Each area is further divided into subtests (see Table 1 below)

Table 1: KeyMaths3UK Areas, Subtests, and Item Counts 

Areas and Subtest  No. of items 
Basic Concepts  
Numeration 49 
Algebra 39
Geometry 36 
Measurement 40 
Data Analysis and Probability  40 
Mental Computation and Estimation 40
Written Computation: Addition and Subtraction 35
Written Computation: Multplication and Division 31
Foundations of Problem Solving 27
Applied Problem Solving 35

The five basic concepts subtests represent a carefully selected set of concepts and skills at each level that form the foundation for mathematics learning and connections across subtests.

KeyMaths3UK also includes two separate written computation subtests (Addition and Subtraction; Multiplication and Division). Operations skills are fundamental for success in mathematics and are often the source of maths learning difficulties.

Applications subtests

The two applications subtests assess a student’s ability to apply conceptual knowledge and operational skills to solve maths problems.

The Foundations of Problem Solving subtest includes items that require students to identify missing elements in a problem, operations needed to solve a problem, and optimal strategies for solving the problem.

The Applied Problem Solving subtest presents maths problems in real-world contexts and includes items that require standard and nonstandard problem-solving strategies.

In-depth subtest topic descriptions and behavioural objectives are included.


Several types of norm-referenced scores are provided, including scaled and standard scores and percentiles.


KeyMaths3UK provides extensive, in-depth coverage across a broad range of mathematical concepts and skills. It has four main uses: 

  • Measures maths proficiency by providing comprehensive coverage of the concepts and skills that are taught in regular maths instruction
  • Measures student progress by providing highly reliable scores
  • Supports instructional development by providing accurate information regarding the specific concepts and skills within the examinee’s functional range
  • Supports educational placement by providing a variety of normative scores, which can be used to identify with accuracy the level at which the examinee is functioning.
