About the school
Herschel Grammar School is a co-educational grammar school with academy status, located on Northampton Avenue in Slough, Berkshire. The school is named after Sir William Herschel, the astronomer who discovered Uranus while living in Slough, and has built a strong reputation for academic excellence and consistently high GCSE and A-level results.
Herschel Grammar School was established in around 1952 in town-centre buildings formerly occupied by Slough Secondary School, before moving to its purpose-built site on Northampton Avenue in 1958. The school has since grown to around 900 pupils, with approximately 250 in the sixth form.

Admissions information
The Herschel Grammar School entrance test is administered through the Slough Consortium of Grammar Schools. Here is everything you need to know about the admissions process and exam structure.
The Slough Consortium consists of four grammar schools in Slough – Herschel Grammar School, Langley Grammar School, St Bernard’s Catholic Grammar School and Upton Court Grammar School – that share a single 11 plus entrance examination. Herschel Grammar School uses the Slough Consortium test results to determine eligibility for a place. The test is provided by GL Assessment and all questions are multiple-choice.
The Slough Consortium consists of two papers, each lasting around one hour, sat on the same day with a short break in between. The papers cover Verbal Reasoning, Non-Verbal Reasoning, English and Mathematics. Answers are recorded on a separate answer sheet and marked using Optical Mark Recognition (OMR).
Registration is completed online through the Slough Consortium portal. For the 2026 examination, registration opens on Friday 1st May 2026 and closes on Friday 5th June 2026. One registration covers all four consortium schools. A child sits the exam in Year 6, in September, for entry to Year 7 the following September.
Results are made available online in mid-October 2026, before the Common Application Form deadline of 31st October 2026. A standardised score of 111 or above means a child is eligible for consideration for a grammar school place, placing them in approximately the top 35% of the cohort. School allocations are confirmed on National Offer Day in March 2027.
