We live in a world in which change is a constant. While change has always existed, lately it has definitely accelerated. There is an idea in society that we should embrace change and adopt whatever is new, with an underlying assumption – wrong to many – that what is new is always better.one that is often wrong

In the world of ELT, new materials are developed every year. It is unthinkable for most teachers to be using teaching materials that were published 10 years ago. Some would even claim that anything published before 2020 is already out-dated.

How does all this impact on the Global Scale of English (GSE) – published over 10 years ago? When it was launched in 2014, it constituted a significant innovation in ELT. The following quotes were provided by ELT experts at the time of launch.

At the beginning of every school year, we welcome new learners into our classrooms with the same core question: Where are our students now, and how far can we take them?

For English teachers, this reveals a huge challenge. In a single class, we might have one student at an A2 level, while others are solidly B1 or just entering A2+. Navigating such a wide range of abilities can feel overwhelming.

We’ve all seen it: students can spend months (or even years) studying English and still feel like they haven’t moved up a level. Teachers work incredibly hard, and students put in the effort, but progress feels intangible. Why is that? And more importantly, how can schools make it easier to see and support that progress?

In recent years, I have found a powerful ally in answering that question: the Global Scale of English (GSE). Backed by Pearson and aligned with the CEFR, the GSE offers more than just levels, it provides a clear, data-informed path to language growth. Most importantly, it gives teachers and school leaders the ability to set meaningful goals and measure real progress.

But, how is this useful at the beginning of the school year?

Starting with assessment

To get a clear picture from the start, assessment is essential; there’s no doubt about it. However, it can't just be a punctuation mark at the end of a term or a requirement from administration. Used strategically, this first assessment can be the compass that guides instruction and curriculum decisions, empowering both teachers and students from day one. This is why choosing the correct assessment tools becomes fundamental.

The GSE difference: Precision, clarity, confidence

Unlike the broad bands of the CEFR, the GSE provides a granular scale from 10 to 90, breaking down each skill into precise learning objectives. This allows educators to monitor progress at a much closer level, often identifying improvements that would otherwise go unnoticed.

When learners see that their score has moved from 36 to 42, even if their overall CEFR level hasn’t changed, they gain confidence. They recognize that learning is a continuous process rather than a series of steps. Teachers, in turn, are able to validate growth, provide clear evidence of learning and tailor instruction to the learner’s current needs, not just their general level.

For example, two students might both be classified as "A2", but the GSE gives us a much clearer picture: a student with a GSE score of 35 is likely mastering simple sentences, while another student scoring 40 might already be comfortable writing simple stories and is ready to tackle B1-level tasks.

This isn't just data: it's a roadmap. It tells us exactly what to teach next, allowing us to differentiate with confidence instead of relying solely on gut feeling.

GSE tools that make it happen

Pearson offers a comprehensive range of GSE-aligned assessment tools that support different stages of the learning journey. Each tool plays a distinct role in placement, diagnosis, benchmarking or certification.

English teachers today face increasing demands: create engaging content, differentiate instruction and address diverse learner needs – all within a limited time. The rise of Generative AI, like ChatGPT, offers a promising solution. But without proper guidance, AI-generated content can lack educational value. This blog post introduces a practical, research-informed approach to using AI tools aligned with the Global Scale of English (GSE). You will learn how this framework helps educators design accurate, personalized and level-appropriate English teaching materials quickly and confidently.

Why GSE and AI are a game-changing combination for ELT

The Global Scale of English (GSE) is a CEFR-aligned framework developed by Pearson, offering detailed "can-do" learning objectives. It includes nearly 4,000 descriptors across speaking, listening, reading and writing skills, offering more precision than traditional level labels like A2 or B1. At the same time, Generative AI tools such as ChatGPT can generate entire lessons, tasks and assessments in seconds. The challenge lies in ensuring this content is aligned with clear pedagogical outcomes.

Pairing AI’s creative speed with the GSE’s structured outcomes offers a scalable way to meet learner needs without compromising instructional quality.

Unlocking measurable, differentiated and efficient teaching with GSE and AI

The GSE makes objectives measurable

Unlike generic teaching goals, GSE objectives are specific and measurable. For example, a B1-level learner objective might state:

“Can identify a simple chronological sequence in a recorded narrative or dialogue.” (GSE 43)
 This clarity helps teachers define outcomes and ensure each AI-generated task targets an actual language skill, not just generic content.

Generative AI enhances productivity

Teachers using Generative AI can create draft lesson materials in minutes. By inputing a structured prompt such as:

“Create a B1 reading activity that helps learners summarize the main points of a short article.”
ChatGPT can instantly generate content that meets the learning goal. When guided by the GSE, AI becomes a collaborative assistant as well as a time-saver.

The GSE + AI combination supports differentiation

Because the GSE includes descriptors across a wide proficiency range (from pre-A1 to C2), teachers can tailor AI-generated content to meet the exact needs of their students. Mixed-level classrooms or tutoring contexts benefit especially from this, as teachers can create multiple versions of a task with consistent scaffolding.

Practical tips

• Use the GSE Teacher Toolkit to select objectives based on skill, level or function.
• When prompting ChatGPT, include the GSE descriptor in your input for more precise results.
• Always review and adapt the AI output to match your learners’ context, culture and curriculum.
• Create a prompt library mapped to GSE codes to save time in future planning.

A step-by-step example of the GSE and AI in action

Here is a typical application of the workflow:

1. A teacher selects a GSE objective, such as:
   “Can write a basic formal email/letter requesting information.” (GSE 46).
2. Within seconds, a sample formal email, accompanied by a short reading comprehension task and a vocabulary activity, is generated.
3. The reading task serves as a model to help learners analyze the structure, tone, and key language features of a well-written email before attempting their own.
4. The teacher then reviews and refines the output for clarity, appropriateness, and context relevance.

This process supports targeted teaching while significantly reducing preparation time.

Overcoming challenges: Ensuring quality and relevance

Challenge: AI outputs may lack cultural context, level appropriateness or instructional clarity.
Solution: Always pair AI with professional judgment. Use the GSE to check that skills match the intended outcome, and adjust the complexity of the language as needed.

Challenge: Teachers may be unfamiliar with how to write effective AI prompts.
Solution: Start simple with templates like:

“Create a [skill] activity at [level] that supports this GSE objective: [insert objective].”

Challenge: Risk of over-relying on AI for instruction.
Solution: Use AI as a starting point, not the final product. Combine AI-generated content with classroom interaction, feedback and your own creativity.

Teaching tools that make this easier
