How teachers can use the GSE for professional development

As English teachers, we’re usually the ones helping others grow. We guide learners through challenges, celebrate their progress and push them to reach new heights. But what about our own growth? How do we, as educators, continue to develop and refine our practice?

The Global Scale of English (GSE) is often seen as a tool for assessing students. However, in my experience, it can also be a powerful guide for teachers who want to become more intentional, reflective, and confident in their teaching. Here's how the GSE has helped me in my own journey as an English teacher and how it can support yours too.

About the GSE

The GSE is a proficiency scale developed by 色猫AV. It measures English ability across four skills – listening, speaking, reading and writing – on a scale from 10 to 90. It’s aligned with the CEFR but offers more detailed learning objectives, which can be incredibly useful in diverse teaching contexts.

I first encountered the GSE while exploring ways to better personalize learning objectives in my Business English classes. As a teacher in a non-formal education setting in Indonesia, I often work with students who don’t fit neatly into one CEFR level. I needed something more precise, more flexible, and more connected to real classroom practice. That’s when the GSE became a turning point.

Reflecting on our teaching practice

The GSE helped me pause and reflect. I started reading through the learning objectives and asking myself important questions. Were my lessons really aligned with what learners at this level needed? Was I challenging them just enough or too much?

By using the GSE as a mirror, I began to see areas where I could improve. For example, I realized that, although I was confident teaching speaking skills, I wasn’t always giving enough attention to writing development. The GSE didn’t judge me. It simply showed me where I could grow.

Planning with purpose

One of the best things about the GSE is that it brings clarity to lesson planning. Instead of guessing whether an activity is suitable for a student’s level, I now check the GSE objectives. If I know a learner is at GSE 50 in speaking, I can design a role-play that matches that level of complexity. If another learner is at GSE 60, I can challenge them with more open-ended tasks.

Planning becomes easier and more purposeful. I don’t just create lessons, I design learning experiences that truly meet students where they are.

Collaborating with other teachers

The GSE has also become a shared language for collaboration. When I run workshops or peer mentoring sessions, I often invite teachers to explore the GSE Toolkit together. We look at learning objectives, discuss how they apply to our learners, and brainstorm ways to adapt materials.

These sessions are not just about theory: they’re energizing. Teachers leave with new ideas, renewed motivation and a clearer sense of how to bring their teaching to the next level.

Getting started with the GSE

If you’re curious about how to start using the GSE for your own growth, here are a few simple steps:

  • Visit the GSE Teacher Toolkit and explore the learning objectives for the skills and levels you teach.
  • Choose one or two objectives that resonate with you and reflect on whether your current lessons address them.
  • Try adapting a familiar activity to better align with a specific GSE range.
  • Use the GSE when planning peer observations or professional learning communities. It gives your discussions a clear focus.

Case study from my classroom

I once had a private Business English student preparing for a job interview. Her speaking skills were solid – around GSE 55 – but her writing was more limited, probably around GSE 45. Instead of giving her the same tasks across both skills, I personalized the lesson.

For speaking, we practiced mock interviews using complex questions. For writing, I supported her with guided sentence frames for email writing. By targeting her actual levels, not just a general CEFR level, she improved faster and felt more confident.

That experience reminded me that when we teach with clarity, learners respond with progress.

Challenges and solutions

Of course, using the GSE can feel overwhelming at first. There are many descriptors, and it can take time to get familiar with the scale. My advice is to start small: focus on one skill or one level. Also, use the Toolkit as a companion, not a checklist.

Another challenge is integrating the GSE into existing materials, and this is where technology can help. I often use AI tools like ChatGPT to adjust or rewrite tasks so they better match specific GSE levels. This saves time and makes differentiation easier.

Teachers deserve development too

Teaching is a lifelong journey. The GSE doesn’t just support our students, it also supports us. It helps us reflect, plan, and collaborate more meaningfully. Most of all, it reminds us that our growth as teachers is just as important as the progress of our learners.

If you’re looking for a simple, practical, and inspiring way to guide your professional development, give the GSE a try. It helped me grow, and I believe it can help you too.

    Clear path to fast-track progress: Why choose assessment underpinned by the GSE

    By
    Reading time: 4 minutes

    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 色猫AV 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

    色猫AV 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.

    What happens in the brain when you learn a language?

    Whether you’re picking up Spanish for travel, Mandarin for business or French just for fun, you’re not only expanding your communication skills, you’re also giving your brain a powerful workout. But what actually happens inside your brain when you learn a language??

    The brain’s language centers

    Your brain is made up of many parts and two areas are significant for language:

    • : Located in the frontal lobe, this region helps you produce speech and form sentences.
    • : Found in the temporal lobe, this area helps you understand spoken and written language.

    When you start learning a new language, these areas get busy. They work together to help you listen, speak, read and write in your new language (Friederici, 2011).
