Choosing the right path through to senior school is one of the biggest decisions you'll make for your son, and the Common Entrance exam sits at the heart of that journey. It is a set of standardised papers, usually taken at 13+ and sometimes at 11+, that many independent senior schools use to understand a boy's academic readiness and offer him a place. Understanding how it works, what it covers, and how schools use the results helps you approach the whole process with confidence rather than worry.

This guide walks through what the exams test, how schools use them alongside scholarships and other entry routes, and practical, gentle ways you can support your son through his preparation. We draw on more than a century of experience within independent schools, and throughout we hold one principle above all: academic ambition matters, but so does raising a happy, resilient boy.

Purpose and Structure of the Common Entrance Exam

The Common Entrance, or CE, at 13+ sets out the academic standard senior schools expect, while also looking at broader skills such as reasoning and extended writing. It is administered by the Independent Schools Examinations Board (ISEB) and is used across many independent senior schools to inform offers and place boys at the right academic level.

What the CE Exam Assesses

The 13+ CE tests a broad, curriculum-based range of subjects. English, mathematics and the three sciences form the core, alongside optional subjects such as modern languages, history, geography, classics and religious studies. Papers look at factual knowledge, technique, and a boy's ability to apply what he has learned to new problems.

The format varies by subject. You can expect multiple-choice and short-answer questions alongside extended essay-style writing in English and the humanities, problem-solving and algebra in maths, and data interpretation and practical-style questions in science. Some language papers also include speaking and listening, arranged by the receiving senior school.

Prep schools often build their teaching around the CE specifications, so rather than testing anything unfamiliar, the exam simply reflects what a well-taught 13 year old should know. It also gives boys valuable practice in reasoning, organisation and exam technique, skills that will serve them well once they arrive at senior school.

Timeline and Registration Process

13+ CE exams normally take place in the summer term, in May or June, timed around the move into Year 9. Senior schools will let you know which papers your son needs to sit, and whether he should take the standard CE papers or the Common Academic Scholarship (CASE) papers if he is being considered for a scholarship.

If your son is with us at prep school, we take care of registering him through the ISEB system as part of our normal process. Families joining from a state or non-participating school may need to register directly with ISEB, or work with the senior school to confirm dates and venues. Deadlines for entry, any access arrangements, and candidate details are set well ahead of time, so it's worth checking both the senior school's admissions timetable and the ISEB registration portal early.

On the day, your son will sit his papers under standard exam conditions, with timings set by the exam centre. Some senior schools also ask for an interview, references or additional assessments alongside CE, so we keep communication open with both prep and senior schools throughout.

Levels and Grading Standards

Most CE subjects are offered at two levels, Core and Foundation, with mathematics also offering an Additional level for particularly able boys. Core is the level most senior schools ask for. CASE papers sit above Core and are designed for scholarship candidates.

Papers are marked out of 100 and translated into grades from A to E. Each senior school sets its own pass mark and scholarship threshold, so the same score can lead to a different outcome depending on where your son is applying. We will always advise on the level that best suits your son, based on how he is progressing and the academic standard of his chosen senior school.

ISEB publishes past papers and subject guidance that reflect what the syllabus expects, and we use these to help boys become familiar with question styles and the level of rigour senior schools are looking for.

Subject Range and Exam Formats

Boys will sit a mix of compulsory core papers and optional subjects, with paper length and style varying across each one. Some subjects also include a spoken element. Every senior school sets its own expectations, so it's always worth checking theirs directly.

Core Subjects and Optional Papers

English, mathematics and science form the core that most senior schools require. English papers typically include comprehension, a shorter writing task, and a longer piece of composition. Mathematics covers arithmetic, algebra, geometry and problem-solving across several timed papers, with calculator rules set individually by each school.

Science is often split into biology, chemistry and physics, or combined into a single paper. Popular optional subjects include modern languages, history, geography, religious studies, and Latin. Some schools ask for a full slate of optionals, others are happy with a smaller selection, so marks are converted to grades according to each school's own thresholds.

Speaking and Listening Assessment in Languages

Modern languages such as French, Spanish and German usually carry a spoken element alongside the written papers. This typically takes the form of a short conversation, in person or recorded, lasting around five to ten minutes, and looks at pronunciation, spontaneous responses and everyday vocabulary.

Listening assessments use audio recordings with multiple-choice or short-answer questions, sometimes as a standalone paper and sometimes woven into the written paper. It's worth checking with each senior school whether speaking and listening forms a formal part of the assessment, as this shapes how we prepare boys and plan the timetable.

Classical Civilisation and Additional Offerings

Latin and Classical Civilisation are offered by many senior schools, often alongside one another. Latin papers test grammar, translation and comprehension, with Core level focusing on set vocabulary and standard prose, and Additional level introducing unseen passages and more complex grammar.

Classical Civilisation explores Greek and Roman history, literature and culture through source analysis and essay writing, and some schools also offer Classical Greek as an option. Beyond these, boys may also be assessed in art, music or design technology, often through practical work or a portfolio rather than a timed written paper.

Foundation, Core and Additional Levels

Papers are set at Foundation, Core and Additional level to match a boy's ability and where he is headed. Core covers the standard syllabus most boys sit, and assumes a secure grasp of the material and the ability to apply it. Foundation is a gentler option, offered where a school wants to give a boy a safety net rather than the full Core demands.

Additional level is aimed at higher-attaining boys and often underpins scholarship assessment. It brings harder questions, more extended problem-solving, and in some subjects, extra papers. Because each school decides which level it wants for each subject, we always encourage families to confirm this early, so preparation can be tailored from the outset.

Entry Pathways and Scholarship Opportunities

The move from prep to senior school can involve formal assessments, informal offers and dedicated scholarship routes, sometimes all within the same application. Understanding how pre-tests, Common Entrance and CASE fit together will help you plan preparation, decide whether additional tutoring is needed, and set realistic expectations together with your son.

Understanding Pre-Tests and Conditional Offers

The ISEB Common Pre-Tests usually take place in Year 6 or Year 8, and give an early, standardised read on ability in maths, English, and verbal and non-verbal reasoning. Senior schools use these results to shortlist boys and issue conditional offers, meaning a place is secured provided later CE or school-specific results meet an agreed standard.

Every senior school treats pre-tests a little differently, some see them as advisory, others as a firmer gateway, so it's always worth checking each school's approach directly. We find the best preparation is steady practice with timed papers and familiar question formats rather than heavy rote learning, always with your son's wellbeing and confidence held front of mind.

CASE and Common Academic Scholarship Exams

CASE, the Common Academic Scholarship Examination, runs alongside CE for boys who are academically strong and being considered for a scholarship. It is more demanding than standard CE, and many schools use it to decide scholarship awards at 13+. CASE papers typically ask for deeper subject knowledge, higher-order reasoning, and more extended writing in English and maths.

If a scholarship is on the horizon for your son, we would encourage an early conversation with us so we can plan a strategy together. Expect additional papers or different formats, and do check whether the school in question combines CASE results with an interview or school reports when making its final decisions. Scholarships can be academic, musical or sporting, and may be honorary, fee-reducing, or both, so it's worth understanding exactly what's on offer before committing to the process.

Transition from Prep to Senior School

Common Entrance at 13+ remains the most common route for boys moving on from prep school, though schools vary in exactly how they use the results. Some treat CE as the formal entry qualification, others combine it with their own assessments. It's worth knowing, for each school you're considering, precisely which subjects are tested and where the grading thresholds sit.

In practical terms, this means gathering past CE papers, focusing revision on the right subjects, and making sure school reports and references accompany the application at the right time. Just as importantly, it's worth talking to your son about the pastoral side of any senior school you're considering, the academic step-up matters, but so does the warmth and support that will help him settle and thrive.

Successful Preparation and Supporting Your Child

The most effective preparation is steady and realistic, balancing syllabus coverage and practice papers with proper rest and time to be a boy. Focus on specific gaps, keep mock exams regular, protect sleep and friendships, and stay closely in touch with tutors and school.

CE Preparation and Past Papers

Past CE and CASE papers are the best way to help your son get comfortable with question styles and timing. We recommend focusing on papers from the last three to four years, matched to the subject and level his target senior school expects.

Short, focused sessions work best: one timed paper a week per core subject, with careful marking and some targeted revision the following day. Keeping track of recurring question types, whether that's algebra, unseen poetry or scientific method, helps build a clear picture of where to focus next.

A simple record of the date, paper, score and two areas to work on gives visible, motivating progress, and helps us set practical goals together with his teachers. Associations such as IAPS, HMC and GSA also offer helpful guidance on required papers, so do confirm the details directly with the senior school in question.

Mock Tests and Timetables

A mock timetable that mirrors exam day, with the same start times, breaks and materials, helps take the mystery out of the real thing. Gradually lengthening papers over time builds the concentration your son will need, without any last-minute cramming.

A gentle, colour-coded weekly timetable that balances English, maths, science and languages with time for sport, hobbies and rest tends to work well. One full mock under timed conditions every three to four weeks, alongside shorter subject-focused mocks weekly, strikes a good balance.

After each mock, we find it's far more valuable to spend time understanding the mistakes than simply redoing the whole paper. That focused, encouraging feedback is what turns practice into real improvement, and steadily reduces any exam nerves along the way.

Supporting Your Son's Wellbeing

Sleep, good food and time with friends are not extras during exam preparation, they're essential. A well-rested boy learns faster and copes far better with the pressure of exams, so we always encourage a quiet evening ahead of any mock or exam.

Simple routines, a bit of outdoor exercise, regular meals, a predictable bedtime, make a real difference. It's worth staying attentive to changes in mood too; withdrawal, irritability or a sudden dip in performance can be a sign your son needs a bit of extra support. Please do speak early with his form teacher, we take pastoral care seriously and are always here to help.

Families sometimes find evidence-based resources such as the Parent Power Toolkit by Tooled Up Education helpful for framing supportive conversations at home, though we're always happy to talk through what might work best for your son specifically.

The Role of Tutors, School and Wider Support

It helps to be clear about who does what: school provides curriculum continuity and pastoral care, while a tutor is best used to target specific gaps, perhaps weaker fraction work, or essay structure, rather than covering everything from scratch.

We're always glad to share progress reports and talk through mock results and how your son is settling, and associations like IAPS, HMC and GSA offer useful guidance on recommended syllabuses and the transition from prep to senior school.

Study groups, informal parent tutoring circles, or our own revision sessions can all help boys feel less alone in the process, and a bit of camaraderie goes a long way. Keeping communication open between you, any tutors and the school means everyone is pulling in the same direction for your son.

Frequently Asked Questions

At what age do boys typically sit the Common Entrance, and how does it fit with the move from prep to senior school?

Boys most commonly sit Common Entrance at 13+, at the end of Year 8, for entry into Year 9 at senior school. A smaller number of schools still use 11+ selection, but for most independent senior schools, the formal academic check happens at 13+.

Your son may already hold an offer from a senior school that is conditional on his CE results, in which case the exam simply confirms the place. Some schools also ask for an interview or school reports alongside the papers.

What subjects are usually examined, and what kind of content should we expect in each paper?

The core subjects are English, mathematics and science (biology, chemistry and physics). English typically brings a mix of comprehension, extended writing and grammar; maths covers arithmetic, algebra and problem-solving; and science combines subject knowledge with some practical interpretation.

Beyond the core, boys commonly choose from modern languages, humanities such as history, geography and religious studies, and classics, including Latin and Greek. Paper length and style vary, some rely on multiple-choice or short answers, others ask for essays or translation.

How can we help our son prepare in a calm, confidence-building way without adding extra pressure at home?

A steady routine of short, focused sessions works far better than last-minute cramming, and builds both skill and confidence over time. Keeping evenings free of intense study, and prioritising sleep, good food and exercise, protects his wellbeing throughout.

Gentle, specific praise, and treating mistakes as part of learning rather than something to fear, makes a real difference. Talking to his teachers about progress helps you focus on the areas that matter most, without duplicating what school is already doing or adding unnecessary stress.

Where can parents find reliable past papers and sample questions, and what is the best way to use them?

ISEB publishes official past papers and exam packs that match the Common Entrance and CASE formats, and many prep schools and reputable tutors provide these too. The ISEB online shop and your son's school are both good places to start.

We'd always suggest using past papers first as a diagnostic tool, and only timing them under exam conditions once a topic has been properly covered. Reviewing answers together, with a focus on technique, is a great way to build both understanding and exam stamina gradually.

How are the Common Entrance and the ISEB assessments linked, and what does that mean for our son's preparation?

ISEB sets the Common Entrance syllabuses and past papers used by most independent schools, and also provides wider guidance and resources for families. Some senior schools add their own thresholds or extra tasks, but most base their expectations on the ISEB framework.

We'd recommend preparing to the ISEB syllabus as a solid baseline, then checking each senior school's specific requirements, whether that's Core-level papers, or Additional and CASE for scholarship candidates.

How demanding is the Common Entrance in practice, and what support is typically offered to protect wellbeing alongside progress?

The exam tests breadth and technique more than specialist depth, so while it is academically demanding, it's usually very manageable with two years of steady preparation. The papers can be longer than boys have encountered before, so pacing and technique matter as much as knowledge.

We build a programme of lessons, mock exams and pastoral support right across Years 7 and 8, and keep a close eye on workload throughout. Booster sessions, regular past-paper practice, and open conversations about stress or confidence are all part of how we support every boy through the process.
