Common Entrance Maths at 13+: What Parents Need to Know
Join us for an overview of what 13+ Common Entrance maths exam covers, how it differs from KS3 and how to help your child prepare.
Parents can hear very different advice about when to begin 11+ preparation, from starting several years in advance to waiting until Year 5 or even Year 6. With such different timelines, it can be hard to know when to start preparing and what your child needs at each stage.
The right timing depends on more than a year group because target schools have their own admissions processes and children may need different amounts of time to prepare. There is no single timeline that works for every child, but understanding the usual admissions process can make the decision clearer.
Today, we’ll look at what the 11+ involves, when preparation typically begins, how to check if your timing is on track and which local resources are available to Notting Hill families.
The 11+ refers to entrance assessments used by selective schools as part of their admissions process for children moving into senior school.
Rather than one national exam, the 11+ takes different forms depending on the school, so assessment formats and requirements vary. For Year 7 entry, children usually take the relevant assessments during Year 6.
Some independent schools use the ISEB Pre-Tests, a set of four online, adaptive tests covering English, mathematics, verbal reasoning and non-verbal reasoning. The tests assess both what children have learned and how they use reasoning and problem-solving skills.
For maths, ISEB’s test framework is based on the National Curriculum Programme of Study up to the end of Year 5, including:
number and place value
addition, subtraction, multiplication and division
fractions, decimals and percentages
measurement
geometry
statistics
Some questions focus on arithmetic fluency, while others ask children to solve mathematical problems using one or more of these areas.
For families in our local community, Notting Hill Prep explains that 11+ processes typically assess English, maths, verbal reasoning and non-verbal reasoning, often through the ISEB Common Pre-Test alongside interviews and group assessments.

11+ maths questions can test both fluency and the ability to use familiarmaths skills to solve problems.
Focused 11+ preparation commonly begins around Year 5, although children can start building the maths foundations they need in Year 4, depending on their current skills and the requirements of their target schools.
The level of preparation can then change as the assessment gets closer. One useful progression is:
Year 4: Strengthen core maths skills and address gaps that could make later 11+ work more difficult.
Year 5: Become familiar with the content and question formats used by target schools.
Year 6: Continue practising the relevant assessment format and build confidence with the types of questions children will encounter before their test date.
Families can start researching target schools before focused preparation begins to keep track of registration deadlines and upcoming assessments.
As a local example, Notting Hill Prep incorporates focused English and maths preparation for 11+ and 13+ pre-tests from Year 5. Children become familiar with the types of questions and expectations they may encounter while continuing with their wider school curriculum, as the school favours firm foundations and a broad education over exam technique in the early years.
For schools that use the ISEB Pre-Tests as their 11+ assessment, families can check the current ISEB calendar for registration and testing dates. Individual senior schools set their own test deadlines, so families should always check the admissions information for each target school.

11+ preparation is on track when children strengthen the maths skills they need for the assessment, become familiar with its format and maintain a healthy balance between preparation, school and other activities.
Parents can assess how preparation is progressing across four areas:
| Area | Signs preparation is on track |
| Maths foundations | Your child understands the maths behind the questions and can use their knowledge to solve problems without relying on memorised exam techniques. |
| Assessment format | Practice includes the question styles and, where relevant, the online format used by target schools. |
| Individual needs | Preparation focuses on specific gaps or skills that still need work instead of treating every topic as equally difficult. |
| Workload | 11+ work fits alongside normal schoolwork and activities without taking over most of your child’s time outside school. |
Children taking the ISEB Pre-Tests should become familiar with the online platform and question styles before test day. ISEB provides familiarisation materials to help children understand what to expect.
11+ work should still support the maths children are learning rather than become a separate cycle of exam practice. Notting Hill Prep takes a similar approach locally by incorporating 11+ skills into its normal curriculum and familiarising children with assessment formats to reduce nervousness around the process.
