The Secondary Transfer Test (STT) Format

Chesham Grammar School selects students based on their performance in the STT for The Buckinghamshire Grammar Schools (TBGS). This is a GL 11 Plus governed by the GL exam board. All 13 schools under TBGS use the STT as their method of selective testing. Notably, if your child attends a state-funded grammar school, they will automatically be entered into the STT for the appropriate year; registration for the STT is therefore only required where your child attended an independent school, or one outside Buckinghamshire. The content of the assessment tests beyond what is taught at primary education level; the test is designed to push candidates with the question difficulty and formatting. The unfamiliar format of the test and its difficulty can seem daunting. The 11 Plus Hero is here to help. We understand and are accustomed to the content of the test; its methodology and method of marking. We can provide a toolkit to your child, familiarising them with the test format and ensuring they have the best chance to succeed.

The STT: Overview

There are four key components to the STT, which is overseen and marked by the GL Exam Board, making it a GL 11 Plus Exam. The STT will assess candidates competency in English, Verbal Reasoning (VR), Non-verbal Reasoning (NVR) and Maths. For an in depth breakdown of the GL 11 Plus in Buckinghamshire, please visit our article ‘Selective Tests in Buckinghamshire – The GL 11 Plus Test’.

 

Overview:

The test consists of two exam papers, each taking approximately 60 minutes in length.

  • Paper One: Verbal Reasoning (VR) & English: VR and English each have their own section.
  • Paper Two: Non-verbal Reasoning (NVR) & Mathematics: NVR will include Spatial Reasoning (SR) too, and will have its own section. Maths will have its own section.

 

TBGS GL 11 Plus Test: Pass Criteria

Test scores are received by October for the following year of entry. For example, for entry in 2023, test scores will be received in October 2022. It is notable that younger children are not penalised for their age, the results are statistically standardised to compare any child’s score average to the average score of their school year. Further, there is no ‘pass mark’, for the STT; instead, admission is based on whether a candidate has met a ‘qualifying score’. This is the minimum aggregate score received upon sitting the STT that a child must receive in order to be eligible for admission to Chesham Grammar School. The qualifying score in Chesham’s 2023 admission policy is stated as 121. However, the ‘qualifying mark’ can vary from year to year. Although the qualifying mark cannot be predicted, it is estimated that the top 25% of students will achieve the qualifying mark. For more information please see our article ‘Selective Test in Buckinghamshire – GL 11 Plus”

Catchment Area

As a prerequisite, a child must achieve the qualifying score (currently 121) in order to be eligible for admission to Chesham Grammar School. The school does operate on a catchment area. This is contained on their website – https://0e58658be539ee7325a0-220f04f871df648cf4a4d93a111e3366.ssl.cf3.rackcdn.com/chesham/uploads/document/Chesham-Grammar-Catchment-2019-onwards.pdf?ts=1527690746 – it is notable that the catchment area is subject to change every year, so please check for the most updated version of the catchment area.
