Coded sequences in 11+ Non-Verbal Reasoning assess a child's ability to identify underlying patterns and rules within a series of abstract shapes or figures. These questions require logical deduction to predict the next item in a sequence or decode the rule governing its progression.
Success in this area hinges on meticulous observation and systematic thinking. Children must analyse how shapes change, rotate, reflect, or combine across the sequence, often with multiple elements evolving simultaneously. Regular practice helps children recognise common patterns and develop efficient problem-solving strategies.
Coded sequences present a series of images that follow a specific, often complex, rule. The task is to deduce this rule and apply it to find the missing image or the next image in the sequence. Each element within the shapes – such as its size, colour, orientation, or the number of components – can change independently or in conjunction with other elements.
Children should be taught to break down each figure into its constituent parts and observe how each part transforms from one step to the next. For instance, if a square contains a circle and a triangle, analyse how the square, circle, and triangle each change across the sequence. This systematic approach prevents overwhelm and helps in identifying all active rules.
Effective strategies are crucial for tackling these questions efficiently. Encourage your child to:
Practising with a variety of question types helps in building a repertoire of recognisable patterns.
While sequences can be unique, several common patterns frequently appear. Familiarity with these can speed up problem-solving:
Encourage your child to categorise the patterns they encounter during practice to build recognition skills.

A coded sequence is a series of abstract figures or shapes that follow a specific, logical rule or pattern. The child's task is to identify this rule and use it to determine the next figure in the sequence or a missing figure.
Coded sequences are a common question type in GL Assessment 11+ Non-Verbal Reasoning papers. They may also appear in independent school exams that include a Non-Verbal Reasoning component.
Improvement comes from consistent practice. Encourage your child to break down each figure into its elements, look for individual patterns (e.g., rotation, size change, shading), and then combine these observations to deduce the overall rule. Timed practice is also beneficial.
Yes, sequences can involve a single rule or multiple concurrent rules. Patterns can include rotation, reflection, changes in size or number of components, alterations in shading or colour, and positional shifts of elements. Some sequences may also involve alternating rules.
