About Southend High School for Boys
Southend High School for Boys is a boys' grammar school with a mixed sixth form in Southend-on-Sea. It's rated 'outstanding' by Ofsted and has been offering an excellent education to boys since 1895. Students at SHSB achieve impressive exam results every year.
The school has a nurturing and innovative environment. The parents' association is thriving, and the alumni network is one of the largest in the UK.
How to apply to Southend High School for Boys
Southend High School for Boys is a selective school. This means that your child will need to take the 11 plus exam to be eligible for a place.
SHSB is a member of the Consortium of Selective Schools in Essex (CSSE). All 10 grammar schools in the CSSE use the same 11 plus exam. This means that your child will only need to take the exam once – even if they’re applying to other schools in the consortium.
The deadline to register for the CSSE 11 plus exam is 27th June 2025. The exam will take place on Saturday 20th September 2025 and you’ll receive your child’s results in mid-October. You can then use these results to decide whether to apply for a place at Southend High School for Boys.
To apply, you’ll need to name the school as one of your preferred schools on the secondary school common application form. This will be available on your home council website from early September and must be submitted by 31st October.
Remember – passing the 11 plus doesn’t guarantee that your child will be allocated a place at your preferred school. Many grammar schools are often oversubscribed with qualified children. Schools and their admissions authorities work through admissions criteria to prioritise children for places. We’ve included the admissions criteria for Southend High School for Boys below.
What subjects are on the entrance exam?

How does place allocation work at Southend High School for Boys?
Each of the two CSSE papers are worth up to 60 marks (120 in total). Your child’s final marks will be standardised and weighted.
Each school in the CSSE sets its own qualifying score, and this varies from year to year. In 2023, a total standardised score of 303 was the lowest score for which boys who live within the priority area were offered a place at Southend High School for Boys. A score of 342 was the lowest score for which boys who live outside the priority area were offered a place at the school.
Of the 180 places available in Year 7 at Southend High School for Boys, 150 are reserved for children who pass the CSSE exam and primarily live within the school's priority area. This covers the postcode areas SS0, SS1, SS2, SS3, SS4, SS5, SS6, SS7, SS8 and SS9. If there are fewer than 150 children from the priority area who have scored the pass mark or higher, then more places will be available for children who live outside of the priority area.
10% of places (15 within the priority area, and 3 outside the priority area) are reserved for children who exceed the pass mark and are ‘looked after’ or ‘previously looked after’ children, or children entitled to Free School Meals.
Atom’s top tips for 11 plus preparation
The 11 plus is designed to select the most academically able children in the country. Here are our top tips to help you and your child feel confident for exam day!
Bitesize learning
It’s important to build a good knowledge base before the 11 plus. Using a ‘little and often’ approach when learning is key – our brains encode new information more effectively when dealing with smaller ‘chunks’ of information. For children aged 10–11, child psychologists recommend regular study sessions of 20–30 minutes.
Atom Home makes learning a more enjoyable process for your child. They'll explore exciting worlds full of interactive questions, earning coins to spend in the Atom shop. Atom adapts to your child, showing them questions at just the right level of difficulty to keep them motivated.
Read widely
11 plus exams test your child’s ability to analyse and interpret written information. Regular reading is a great way to help your child build these skills.
Encourage them to read books from different genres and by a diverse range of authors. Increasing the variety of your child’s reading will help them understand different styles, tones and purposes. Meanwhile, reading a little every day will help widen their vocabulary, sharpen their analytical thinking, and enhance their imagination.
Refine exam technique
When your child feels confident with the topics they’ve learnt in Year 5, they’ll be ready to put their knowledge to the test.
Practice tests can help your child develop problem-solving skills and build confidence working under test conditions. They’re also a great way to consolidate learning and highlight knowledge gaps for further improvement.
With Atom Home, you'll unlock online mock tests and printable practice papers. Enjoy automatic marking and progress tracking with the online tests, and help your child get familiar with the real exam experience with printable practice papers.
Celebrate progress
Setting regular, achievable goals and celebrating your child’s progress – no matter how big or small – will help keep their motivation high.
Make sure to encourage a growth mindset. This means celebrating effort, as well as achievement! When your child makes mistakes or struggles to understand a particular topic, help them understand that they’ll improve through practice. Regular praise will help your child improve their resilience when tackling new and challenging topics.
