What are the ISEB Pre-test Assessments?
ISEB tests by the Independent Schools Examinations Board are online exams that assess the academic abilities of a student for entry into an independent secondary school in the UK. The tests are adaptive, and as the name suggests, they change the level of difficulty based on your child.
They give schools an accurate and reliable measure of the potential and preparedness of a student for work in a demanding academic setting.

What is Changing at ISEB from 2022?
ISEB Test Changes
The ISEB Pre-Test saw multiple changes in 2022, with a new provider taking over from GL Assessments. Here’s what you need to know:
Most Important: Registration Process
It is now necessary for parents to independently register their children for the ISEB Test, rather than the previous system in which registration automatically took place via their chosen senior school.
Exam Format
- The English section now provides two separate scores: one for comprehension and another for SPaG (spelling, punctuation, and grammar).
- Instead of a single long passage, the English comprehension section now features several shorter texts, each with fewer associated questions.
- The full text of the comprehension passages can now be viewed by scrolling, children no longer need to click through multiple pages.
Content Updates
- A new question type, “how many cubes,” has been added in the non-verbal reasoning section.
- The question bank has been expanded to include more individual questions. Apart from the new cube-related questions, the types of questions students need to prepare for remain the same.
Improved Accessibility
- Students have the option to hide the timer to minimise distractions.
- There are options to adjust the font size and apply a colour overlay to make the questions easier to read.
- All students are permitted to use pencil and paper for notes and rough work throughout the entire test, a change from previous years when this was restricted to certain subjects.

How to register your child for the ISEB Pre-test?
Before your child sits the ISEB Pre-Test, they must be registered through the new ISEB guardian portal.
Registration is free of charge. You only need to register your child for the test once, no matter how many schools they sit the exam for.
What is in the ISEB Pre-test?
The ISEB Pre-Test includes four tests: English, Maths, Verbal Reasoning (VR), and Non-Verbal Reasoning (NVR). The test takes 2 hours and 15 minutes to complete.
It is completed online and can be taken in one day or across multiple days at any time. The tests are adaptive, meaning that each student receives a unique set of questions. You can not go back and change previous answers. The tests are taken in Year 6 for entry to Year 7 or Year 9. Results are available to the senior school you are applying to immediately.
What is in the Maths Section of the ISEB Pre-Test?
The Mathematics questions in the ISEB Pre-Test cover topics including:
- Number and place value
- Calculations (addition, subtraction, multiplication and division)
- Fractions, decimals and percentages
- Measure
- Geometry
- Statistics
Some questions may be straightforward calculations, some may cover more than one topic, while others might be problem-solving.
Number questions come up more often.
Questions are multiple-choice.
Use a piece of paper to help with your working out. Working out is not marked.


What is in the English Section of the ISEB Pre-Test?
The English Section of the ISEB Pre-Test contains two sections.
Questions are multiple choice and are based on the KS2 national curriculum.
The test is up to 40 minutes long.
Section 1: Reading Comprehension.
The test contains several passages. They may be fiction, non-fiction, or poetry.
Each paragraph or verse is numbered.
Questions will either refer to a specific paragraph, sentence (specified in the question) or the whole text.
The tests aims to assess the following skills:
- Literal: Understanding details explicitly stated in the passage.
- Deduction: drawing logical conclusions on what must be true from what is given in the text, backed by prior experience and knowledge of the world.
- Inference: Drawing an implied meaning not directly stated in the passage.
- Vocabulary: Understanding of words in context.
- Summarising: Expressing concisely the relevant points.
- Literary Devices: Picking out and making sense of techniques such as personification, alliteration, similes, metaphors, and more.
- Comparative Analysis: Comparisons are made across the text, between characters, or in Levels of Formality.
Section 2: Grammar
The Grammar section of the ISEB Pre-Test assesses the following skills:
- Spelling: Understanding spelling rules and where they do not apply.
- Punctuation: Understanding how to use punctuation correctly.
- Grammar: Understanding different word types (adjectives, verbs, adverbs, and more), tenses, sentence structures, formal and informal language, and more.
- Vocabulary: Understanding word meaning, word families, prefixes, and suffixes.
There are three types of questions in this section:
- Cloze Sentences – your child will be expected to fill in the blank space in a sentence.
- Shuffled Sentences – your child will be expected to rearrange a sentence so it is in the correct order.
- SPaG (Spelling, Punctuation and Grammar) – spot the mistake type question.
What is in the Verbal Reasoning Section of the ISEB Pre-Test?
The verbal reasoning section of ISEB Pre-Test is typically 25 minutes long. They aim to assess your child’s logic and comprehension skills.
Questions can ask the child to:
- Analogy – comparing two pairs of words that highlights their similarities.
- Compound Words – two words that can be joined together to make a new word.
- Embedded Words – hidden word at the end of one word and the beginning of the next word.
- Form a Word – combining words using rules to create a new word.
- Insert a Letter – identify a letter that completes the end of one word and the beginning of another.
- Letter Codes – identify the pattern in a set of letters to crack the code to form a new word.
- Letter Sequences – work out the missing letters in a sequence.
- Move a Letter – move one letter from the first word and put it into the second word.
- Number Analogies – find the relationship between numbers and select similar pairs or numbers.
- Synonyms – find words which mean the same thing, or are closest in meaning.
- Word Completion – find the missing word that completes a longer word.
- Word Opposites – find a word from a set that is opposite in meaning to the others
- Word Pairs – identify a pattern within the word pairs presented to find the missing word from the last pair.
- Word Relationships – find the relationship between a set of words and apply that relationship to find the answer


What is in the Non-Verbal Reasoning Section of the ISEB Pre-Test?
The non-verbal reasoning section of the ISEB pre-test usually lasts around 30 minutes.
Instructions on how to answer the question are given before each question.
This test assesses your logical, critical thinking and problem-solving skills through shapes, figures and diagrams.
The exam contains two types of questions:
- Analysing 2D figures: spotting the differences and similarities, finishing diagrams, spotting patterns, predicting and code matching.
- Manipulating 3D figures and diagrams to view them in a different way.
New type of questions: ‘how many blocks?’ and ‘silhouettes’.
What Score does my Child need to get the ISEB Pre-Test Assessment to Pass?
Your child will be given a standardised age score (SAS) once they have completed the test.
It does not matter the time of the academic year they sit the test or how old they are.
There is no set pass mark for the ISEB Pre-Test as every school has different requirements, but you want to be aiming for at least 115 (SAS) or 120+ (SAS) if you are applying for a highly academic independent school.
100 is the average score, and 80 is low.
The SAS is calculated on the following:
- Number of questions answered correctly and incorrectly
- The difficulty of questions answered
- The age of your child
Do not worry if your child is a summer baby, younger students get extra marks added, but older students will never lose marks.
Results will be sent directly to the school they are applying for. You will not see the results.
Is the ISEB Pre-Test Accessible for SEND Students?
The ISEB Pre-Test is accessible for SEND pupils.
Their online testing platform has the following feature to support SEND students:
- Adjustable font size.
- Students can select a coloured overlay of their choice to improve the visibility of the questions.
- Visible timer (even for students with 25% extra time), the timer can also be hidden if it makes pupils anxious.
- Question instructions are simple and easy to follow.
Where suitable, students are given 25% extra time.
Other arrangements that can be made:
- A reader
- Supervised rest breaks
- A separate room
When you register on the ISEB website, you can apply for extra time or other arrangements. You must let the school know of your child’s needs. The arrangements must be approved by the school before the exam.
ISEB Pre-Test is also accessible for EAL students (students with English as an additional language). You must discuss this with the senior school you are applying to. They may provide you with extra time or a bilingual dictionary.
How to Prepare My Child for ISEB Pre-Test?
Preparing your child for the ISEB Pre-Test can seem overwhelming, but with a structured approach, you can help them feel confident and ready.
Here are some practical steps to guide their preparation:
- Make sure they understand the exam format.
- Ensure they are confident with the national curriculum before they tackle practice papers.
- Create a study plan with a balanced routine that includes practice for each section of the test, with regular breaks to keep your child motivated.
- Teach exam techniques like eliminating wrong answers, reading questions carefully, and managing stress during the test.
- Support your child’s mental and physical well-being by ensuring they get enough rest, eat well, and stay active.
- Practice papers and online resources are excellent tools for building familiarity with the test. Focus on areas where your child feels less confident and track their progress.
While some independent preparatory schools help prepare children for verbal and non verbal reasoning, state schools do not. Here are a few ways you can help your child with verbal and non-verbal reasoning:
Verbal reasoning:
- Ask your child to find certain words in a story e.g. words that end in -ight or -ness, or compound words.
- Play games such as Scrabble, Articule, Bananagrams and Scrabble.
- Write coloured post-it notes around the house with key terminology.
- Create a word bank with new words. Make sure you learn their meaning through repetition and putting them into context!
Non-verbal reasoning:
- Playing spot the difference. A lot of NVR questions involve this.
- Play with LEGO, Laser Pegs and shape puzzles! This improves spatial awareness.
- Download apps such as learning patterns.

FAQ’s
Your child can sit the exam when and where they choose to. There is no ‘best time’ as they will be given a standardised age score (SAS) which takes into consideration when your child sits the exam during the academic year.
No, your child should attempt every question to the best of their ability. The ISEB Pre-Test is an adaptive assessment, meaning the difficulty adjusts based on their responses. Skipping questions may not be beneficial, as each answer helps determine the level at which they are performing. However, if they are truly stuck on a question, it is better to make an educated guess rather than leave it blank.
There is no fixed number of questions that your child must answer. The test is time-limited, and they should aim to work efficiently while maintaining accuracy. Since it is an adaptive test, the number of questions may vary, and the focus should be on answering as many questions correctly as possible rather than rushing through.
After your child completes the ISEB Pre-Test, their results are sent directly to the schools they have applied to. The schools will then use these scores, alongside other admissions criteria such as interviews, school reports, and references, to determine whether your child will be invited to the next stage of the admissions process. Some schools may have additional assessments or exams as part of their selection process.
