GL Assessment 11 Plus Explained: What It Is, How It Works, and Why the Provider Matters

GL Assessment 11 plus explained — if your child is sitting the Kent Test, they are sitting a GL Assessment test, whether you realise it or not. Understanding what GL Assessment is, how its tests are structured, how it differs from CEM (the other major 11 plus test provider), and what specific characteristics define the GL Assessment format is fundamental to choosing the right preparation materials.

What is GL Assessment?

GL Assessment is one of the two principal providers of 11 plus selective entry tests in England. Formerly known as NFER-Nelson, GL Assessment produces standardised tests used by local authorities and schools across the country for selective secondary school admissions. They are used in Kent, Kent, Essex, parts of the West Midlands, and various other selective areas. GL Assessment has been producing educational assessments for decades and maintains large normative databases that underpin the age standardisation process.

GL Assessment vs CEM: The Essential Distinction

CEM (Centre for Evaluation and Monitoring, part of Durham University) is GL Assessment's main competitor as an 11 plus test provider. CEM tests are used in areas including Birmingham, Wiltshire, parts of Yorkshire, Gloucestershire, and Worcestershire. The differences between GL Assessment and CEM tests are fundamental and significant enough that practice materials designed for one are not effective preparation for the other.

GL Assessment tests use discrete, clearly labelled sections for each subject type — verbal reasoning questions in one section, NVR questions in another. The question type is signalled at the start of each section. Questions within a section all follow the same format. This structure means children can learn specific question types and develop a strategy for each one. CEM tests use a more integrated approach where reading, vocabulary, mathematics, and reasoning skills are blended across sections rather than separated — the format is more holistic and considerably less susceptible to drilling of specific question types.

Key Features of GL Assessment Tests

Multiple choice throughout — answers selected from options and marked on a separate answer sheet. Discrete question types that can be practised deliberately. Machine marking of answer sheets. Age-standardised scoring into English, maths and reasoning totals for Kent. Always prefer GL-style materials labelled for Kent preparation.

Why the Provider Matters for Preparation

Because GL Assessment tests use discrete question types in consistent formats, preparation through systematic question-type practice is highly effective. This means that practice papers must be labelled as GL Assessment format or GL-style to be appropriate for Kent preparation. Papers labelled CEM-style or designed for specific CEM areas are structured completely differently and will not prepare a child for the specific formats, question types, and timing structure of the Kent Test. Always check the provider's labelling before purchasing any practice material.

Key Takeaways

  • GL Assessment produces the Kent Test papers — use GL-style preparation materials that reflect the current Kent format
  • CEM is GL Assessment's main competitor — their tests are fundamentally different in structure and approach
  • GL tests use discrete, labelled sections with consistent question type formats — this structure makes systematic preparation highly effective
  • Multiple-choice papers use a separate answer sheet; there is also a writing exercise
  • Official GL Assessment familiarisation materials are the gold standard for preparation accuracy
  • Always verify that practice papers are explicitly labelled GL format before purchasing

Frequently Asked Questions

How do I identify GL format vs CEM format practice papers?

GL-format papers have distinct labelled sections for each question type (verbal reasoning, non-verbal reasoning, etc.) with multiple choice options. CEM-format papers are more reading-integrated and look structurally different. Publisher descriptions typically specify the format.

Does GL Assessment change its format each year?

The overall structure is consistent from year to year. Specific papers change annually. GL Assessment has added spatial reasoning more prominently to Kent Tests in recent years — ensure preparation materials are current and include this subject area.

What does NFER have to do with GL Assessment?

GL Assessment was formerly known as NFER-Nelson — these are the same organisation at different points in its history. Older practice materials may be labelled NFER; these are produced by the same provider, though newer materials are more representative of the current format.
