CEM 11 Plus — fast-paced, unpredictable and highly competitive

Know The Provider

What Is CEM?

CEM stands for Centre for Evaluation and Monitoring and is part of Durham University. It is one of the two main providers of 11+ entrance exams in England, alongside GL Assessment. CEM was developed specifically to create a more school-curriculum-based assessment that is harder to prepare for through rote practice and coaching. The format is deliberately varied from year to year to discourage hot-housing and to identify children with genuine academic ability.

CEM is still very much active and continues to be used widely across several grammar school regions. Its papers are considered more unpredictable than GL Assessment, which makes thorough and broad preparation especially important for children sitting the CEM 11 plus.

Coverage

Which Schools & Regions Use CEM?

CEM is used by grammar schools across several important regions of England.

RegionDetails
BuckinghamshireAll 13 grammar schools in Buckinghamshire switched to a CEM-style test for their Secondary Transfer Test
Birmingham & West MidlandsSeveral Birmingham grammar schools including King Edward VI Foundation schools use CEM-based papers
GloucestershireGrammar schools including Pate's Grammar use CEM Assessment papers
WarwickshireGrammar schools in Warwickshire including Alcester and Stratford use CEM tests
ShropshireHaberdashers' Adams and other grammar schools in the county use CEM-style papers
Cheshire & North WestSeveral grammar schools in and around Cheshire use CEM-based assessments
Other AreasVarious individual grammar schools and some independent schools across England also use CEM papers

Always confirm with your specific target school whether they use CEM, as formats can change and some schools use a mix of providers.

Exam Structure

CEM Exam Format

One of the most important things to understand about CEM is that the format varies deliberately. The structure can change between regions and from one sitting to the next, which is why broad skills-based preparation is essential rather than drilling one specific layout.

FeatureDetails
Answer FormatTypically multiple choice or standard answer, depending on the region and paper
DeliveryPaper-based (not online)
Adaptive?No — fixed format, all children answer the same questions in the same paper
Number of PapersUsually 2 papers, though some regions use 3 shorter sections within those papers
DurationEach paper typically lasts around 45–60 minutes including instructions
Format VariabilityCEM deliberately varies question types and section lengths to reduce the effect of coaching
Mixed SubjectsSubjects may be mixed within a single paper rather than each subject having its own paper

What’s Tested

Subjects Covered

CEM typically tests three main areas, though how they are grouped within papers can vary.

English & Verbal Reasoning

Reading comprehension, vocabulary, synonyms, antonyms, cloze (gap-fill) exercises, spelling and verbal reasoning elements are often combined into one section. A wide vocabulary is essential.

Mathematics

Numerical reasoning, arithmetic, problem-solving, data interpretation, shape, space and measures. Questions often test application rather than just calculation, requiring strong reasoning alongside number skills.

Non-Verbal Reasoning

Not always included depending on the region, but where tested it covers pattern recognition, sequences, spatial reasoning and matrix completion. Some CEM regions have removed NVR entirely from their papers.

CEM deliberately blends English and verbal reasoning into a single section. This is different from GL Assessment where subjects are kept separate. Always check your region’s specific subject combination.

Question Types

Typical Question Style

Extreme Time Pressure

CEM papers are notorious for their very tight time limits. Children often cannot finish all the questions and are expected to work through sections extremely quickly. Speed is as important as accuracy.

Unpredictable Mix

Unlike GL, CEM papers do not follow a rigid predictable structure. Different question types appear throughout each paper and the mix can change from sitting to sitting, making broad preparation vital.

Vocabulary-Heavy

CEM places a particularly strong emphasis on vocabulary. Children with wide reading experience and a large word bank have a significant advantage. Vocabulary building should begin well before Year 5.

Results

Scoring & Results

AspectDetails
Score TypeStandardised Age Score (SAS) with an average of 100 and standard deviation of 15
Age AdjustmentRaw scores are adjusted for the child's age at the time of the exam so older and younger children within the year group are compared fairly
Competitive ScoreA score of around 118–121 or above is generally considered competitive, though thresholds vary significantly by school and region
Qualification MethodSome areas use a qualifying threshold (pass/fail), while others rank all candidates and offer places to the highest scorers
Results DeliveryResults are released by the local authority or school, typically in mid-October, ahead of the secondary school application deadline
TransparencyCEM does not publish past papers, which makes familiarisation practice more challenging than with some other providers

Sign Up

Registration

For state grammar schools using CEM, parents register directly with the school or through the local authority rather than through CEM itself. Registration typically opens in the spring or early summer of Year 5 and closes several weeks before the exam date. Some areas automatically register all children living within the catchment area, while others require parents to complete an application form. Out-of-area applicants can usually apply but should check whether any additional steps are needed and must be aware that deadlines can differ from in-area residents. Always visit your local authority or target school website for the most accurate and up-to-date registration guidance, as processes vary considerably between regions.

Preparation

How To Prepare

Build Vocabulary Constantly

CEM's English and verbal reasoning sections depend heavily on vocabulary breadth. Encourage wide reading across fiction and non-fiction from Year 3 onwards. Introduce a word-a-day habit and use vocabulary games regularly.

Practise Varied Question Types

Because CEM does not publish official past papers, use reputable CEM-style practice materials from publishers such as CGP and Bond. Vary the types of comprehension passages, cloze tests and maths reasoning questions your child encounters regularly.

Train for Speed Under Pressure

CEM is famous for its time pressure. Practise timed sections from early in Year 5 to build pace. Teach your child to skip questions they are stuck on and return to them. Never let them spend too long on one question.

Parent Questions

CEM 11 Plus — FAQs

CEM (Centre for Evaluation and Monitoring) is part of Durham University and is one of the two main 11+ providers in England. The key difference from GL Assessment is that CEM deliberately varies its format to reduce the advantage of coaching. It blends English and verbal reasoning into one section, has extremely tight time limits and does not publish official past papers. GL Assessment follows a more predictable structure with separate subject papers.
