Exam intelligence brief
Premium admissions analysis built from the current evidence stack
Chislehurst and Sidcup Grammar
11+ exam brief for parents: how the process works, how competitive it really is, and what current evidence says about the score profile needed.
Editorial read
Officially, "Only pupils who have sat the Bexley Selection Test and who are deemed selective will be eligible to be considered for entry to the school." The school also says "The selection process is extremely competitive." The provided evidence does not include a clean published Chislehurst & Sidcup qualifying score or final offer score. The homepage notes only that "The overall pass mark is also up a fraction on last year," without giving the figure.

What the score really means
Use this as a planning guide, not a guaranteed cutoff.

Plain-language interpretation
In plain English: the school does not publish a guaranteed pass mark. Use no official pass mark as a working guide, and read the competitive range band as the point where every extra mark matters.

Historical trend
For September 2025 entry, the school says 5856 children sat the Bexley Selection Test and 2009 (34%) were deemed selective. For September 2026 entry, 5866 sat the test and 2070 (35%) were deemed selective. This confirms sustained competition across the Bexley grammar system, but not a published school-specific offer-score trend.
Waiting-list reality
Official appeals guidance warns that "although their child’s score may be just one mark under the selective score, there may be 90 or more students who also scored at that mark."
What strong preparation looks like
Prep roadmap
Strong candidate profile
The profile of stronger candidates is still being expanded from the current evidence base.
Borderline profile
Borderline-candidate guidance is still being refined from the score and waiting-list evidence.
Focus areas to prepare
Common misconceptions
- Passing the Bexley test does not guarantee a place at this school.
- A near-miss score is not rare; the school notes there may be many pupils on the same mark just below the selective threshold.
- Strong exam performance alone may not be enough if interview and overall profile also matter.
- This school confirms eligibility depends on being deemed selective in the Bexley Selection Test, but the evidence supplied does not give a clean published Chislehurst & Sidcup offer score for National Offer Day.
What happens after the test
Results & waiting list
Waiting-list intelligence
- Official appeals guidance warns that "although their child’s score may be just one mark under the selective score, there may be 90 or more students who also scored at that mark."
- There is a Headteachers’ Appeal / September Review process before National Offer Day, followed by the normal independent appeals process after offers are made.
