Chislehurst and Sidcup Grammar School 11 plus is a well known mixed grammar option in Sidcup, often chosen by families who want a selective academic setting with a broad intake and a clear, structured approach to learning. The school sits close to Sidcup High Street and is within reach of several main travel routes, so the daily commute often becomes part of the decision early rather than an afterthought.
Families usually feel more settled once two points are clear. First, Chislehurst and Sidcup Grammar School admissions are part of the Bexley Selection Test system, not a school written entrance exam. Second, qualifying as selective does not automatically mean an offer. The test confirms eligibility, and then published oversubscription rules decide how places are allocated.
It helps to map the full grammar school application UK timeline before Year 6 becomes crowded with school events and deadlines. This step by step guide on your site helps keep the process realistic and manageable from the start: grammar school application UK timeline.

For September 2026 entry, the most reliable reference point is the school’s published Year 7 admission arrangements, which explain eligibility, priority criteria, distance measurement, waiting lists, and appeals.
Chislehurst and Sidcup Grammar School selection is based on the borough wide Bexley Selection Test. Families must register during the published registration window set by the local authority. The council’s Starting at Secondary School guidance for September 2026 explains who should register, how to do it, and what happens next.
Registered children sit the test in September of Year 6, usually in one session with two multiple choice papers and a short break. The papers are taken under timed conditions, which is why stamina and calm pacing matter as much as raw ability.
The published description of the Bexley test explains that it assesses comprehension and verbal ability alongside numerical reasoning and non verbal reasoning. Verbal skills form a large part of the overall outcome, but weaker performance in any area can still affect the final selective decision.
Because GL Assessment provides the papers for this route, many families find it helpful to use free official familiarisation materials so the multiple choice layout and timing feel familiar well before test day. These materials are designed to build confidence with format without overloading your child.
Registering for the test does not replace applying for a Year 7 place. Offers are made through the secondary application process. Most London families apply online using eAdmissions, which allows preferences across boroughs to be ranked in one place.
Results are usually shared in October, before the secondary application deadline. Families often use the outcome to judge how realistic each grammar preference is. The council updates families through its Bexley Selection Test results information, which is the best source for confirmed timelines.
National offer day is in early March. Waiting lists can move after that point as families accept other schools or change plans. If a place is not offered, parents have the right to appeal. Many families find it helpful to read clear guidance on appeals from ACE Education so expectations stay realistic and evidence focused.

Chislehurst and Sidcup Grammar School does not operate a simple catchment guarantee. The first layer is meeting the Bexley selective standard. After that, places are allocated using the school’s published oversubscription rules.
Distance is measured as a straight line from the home address to the school entrance point named in the admissions arrangements. Travel time is not considered, which means similar distances can still result in very different daily journeys.
A calm way to think about offers is in layers:
Doing one real journey at school start time can help the routine feel practical rather than theoretical. Many families use the TfL Journey Planner to test routes from Sidcup, Bexleyheath, and Chislehurst early.
There is no interview for Year 7 entry at Chislehurst and Sidcup Grammar School through the Bexley route. Selection is based on test performance and the published admissions criteria.
Key skills tested include careful reading, quick language understanding, accurate application of number knowledge, and recognition of visual patterns. Because the papers are multiple choice and timed, pacing, sensible skipping, and checking answers matter just as much as solving the question.
Preparation works best when it feels like training rather than judgement. For Chislehurst and Sidcup Grammar School, the main themes are strong reading comprehension, verbal reasoning technique, number confidence, and steady non verbal pattern recognition.
