About Chislehurst and Sidcup Grammar School
Chislehurst and Sidcup Grammar School has been providing exceptional education in the London Borough of Bexley since 1931. Originally established as Sidcup County School for Boys, the school became co-educational in 1973, reflecting its commitment to providing outstanding academic opportunities for all students regardless of gender.
Under the leadership of Headteacher Nigel Walker, who has guided the school since 2009, the institution has undergone significant transformation and modernisation. The school's motto, "Abeunt Studia In Mores" (Through study character grows), encapsulates its philosophy that academic excellence and character development go hand in hand.
The school has invested over £10 million in the past decade to enhance its facilities, creating purpose-built spaces for art, music, technology, performing arts, and computing. These state-of-the-art facilities ensure that students have access to the resources they need to excel across all areas of the curriculum, from traditional academic subjects to creative and technical disciplines.
With over 1,400 pupils, the school maintains a vibrant learning community whilst ensuring personalised attention for each student. The school's location in Sidcup provides easy access for families across South East London and North Kent, making it an attractive option for parents seeking high-quality grammar school education.
The 11+ Assessment Process
Entry to Chislehurst and Sidcup Grammar School is through the Bexley Selection Test, a competitive examination designed to identify the most academically able students in the borough. The assessment consists of two comprehensive one-hour papers that evaluate students across multiple cognitive areas.
Test Components:
- English comprehension - assessing reading skills and language understanding
- Mathematics - covering numerical reasoning and problem-solving abilities
- Verbal reasoning - evaluating logical thinking with words and language
- Non-verbal reasoning - testing spatial awareness and pattern recognition
All questions are presented in multiple-choice format, allowing students to demonstrate their knowledge efficiently within the time constraints. The test is designed to be challenging yet fair, identifying students who will thrive in the rigorous academic environment of a grammar school.
Selection Criteria:
There is no predetermined pass mark for the Bexley Selection Test. Instead, the 180 highest-scoring candidates applying to each Bexley grammar school become eligible for places. This competitive approach ensures that only the most academically capable students gain entry, maintaining the school's high academic standards.
The success rate is approximately 30% of test-takers achieving scores sufficient for grammar school consideration, highlighting the competitive nature of the selection process.
