What do we mean by English fluency, and how can understanding competencies across the four skills provide a more realistic picture of communicative English ability?

What is fluency?

As someone who worked in dictionaries, the meaning of words has always interested me – and fluency is a particular case in point. Language learners often set themselves the goal of becoming fluent in a language. Job adverts often specify “fluent in English or Spanish” as a requirement. But what does being 'fluent' in a language actually mean? If we look in the Longman Dictionary of Contemporary English, we see that fluent means “able to speak a language very well”. Fluent speech or writing is described as “smooth and confident, with no mistakes”. In general, fluency is most often associated with spoken language – but is that the goal of all language learners? And what does being able to speak fluently show about the other language skills?

Describing English proficiency

Before entering the world of dictionaries, I taught English as a foreign language in France. At that time, the Common European Framework of Reference for Languages (CEFR) had not yet been published and learners were described in very general terms – beginner, intermediate, advanced – with no agreed standards on what learners at each level were expected to know. As well as establishing standards, the CEFR also shifted the focus of language assessment from knowledge of grammar and vocabulary to functional competence, i.e. what can a student actually do with the language they’re learning across the four skills:

  • listening
  • reading
  • speaking
  • writing

Interestingly, while calling out specific objectives for each skill, almost two-thirds of the information in the CEFR describes spoken language. This seems to imply that spoken fluency is indeed the most important goal for all language learners.

Mapping out a personalized path to proficiency

As a global publisher, app English recognizes that all learners are different – in their backgrounds, learning environments and learning goals. This is why we have undertaken new research to extend the set of learning objectives contained in the CEFR to account for learners who need detailed information about their level in all four skills, not just in one (typically, that of speaking).

No learner will be equally proficient in all four language skills – in the same way that no native speaker is equally proficient in all skills in their first language. Some of us are better at writing than speaking, and many are illiterate in their first language. A true measure of language proficiency needs to take into account all of the skills. Equally, not every learner of English will need to be 'fluent' in spoken communication.

Many researchers need to read papers in English and attend conferences in English – but will only ever present and write in their first language. Is 'fluency' a good way to describe their goal? And if it isn’t, does that somehow diminish their language achievements? By acknowledging proficiency in individual skills – rather than catch-all terms such as 'fluent' – we gain a clearer understanding of goals and outcomes, and with this knowledge, we are in a better position to tailor learning to the individual.

    Kirsty Murray taught English for a year at a collège (the French equivalent of a secondary school) in Villers-Cotterêts: a town in the north of France known for being the birthplace of Alexandre Dumas. She taught mixed-ability groups of 11- to 16-year-olds, with classes ranging in size from 10 to 35 students. Here, she shares the five lessons she learned from the experience.

    How teachers can use the GSE for professional development

    By Fajarudin Akbar
    Reading time: 4.5 minutes

    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 app. 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.
