There’s the saying, “There are two types of teachers with 20 years of teaching experience: the first are those with 20 years of experience and the second are those with one year’s experience repeated 20 times.”

Some believe most teachers want to be the first kind of teacher – constantly evolving throughout their careers – rather than repeating the same classes. Additionally, taking professional development courses can help us reach these new heights.

Doctors, engineers, lawyers and other professionals regularly have to seek training opportunities. This enables them to keep up to date with the latest technologies, innovations and changes in the wider world. It could be argued that teachers are no different.

Benefits of professional development training

There are several benefits to continued professional training for teachers. For instance, there’s always something new to learn as developments are happening regularly in the world of ELT. Whether it’s innovations in ed-tech, new research into how we learn languages or a new pedagogy, certain courses can help bring you up to speed with these!

Undertaking further training will help you to deepen your knowledge and widen your expertise. So rather than simply repeating the same method of teaching a grammar point over again, you’ll learn new approaches. In turn, you’ll be better equipped to find the tools that work to help your students reach their learning goals.

Another great thing about professional development is that it can lead to career progression and promotion. There are a number of courses that you can take to develop not only skills for teaching, but other roles in the ELT industry.
For example, you can train to become a director of studies, specialize in business or academic English, or enter ELT publishing or management. There are many options to explore through further education!

New trends in English language teaching

To be the best teachers we can be, it's important to be aware of new trends in the field of ELT. Some of the latest ones include:

Hybrid learning

Gaining popularity in recent years, hybrid learning is an approach to teaching. Specifically, it involves some students attending class in person, while others join the class virtually from home. This means that teachers must be prepared to simultaneously teach both students in person and online.

Flipped classroom

A flipped classroom means students are introduced to content at home. Often teachers introduce this via videos and then practice working through the new knowledge in class. This is the opposite of the more traditional method where they are given new content at school, and complete assignments independently at home.

Bite-sized learning

One method of teaching that has become more common is bite-sized learning. For example, breaking down information into smaller chunks instead of having learners listen to long, uninterrupted sessions, and this helps students absorb information and keeps them engaged.

If you’re not already familiar with these, there are lots of professional development courses that teach you how to use them in your classroom.

Formal qualifications in ELT

So what courses can you take? Here are some of the most common courses you can take for English language teaching.

  • CELTA (Certificate in Teaching English to Speakers of Other Languages) - Cambridge’s Level 5 qualification is an internationally recognized ELT course. While this certificate focuses on teaching adults, language academies accept it for both adults and young learners.
  • Trinity CertTESOL (Certificate in Teaching English to Speakers of Other Languages) - Like the CELTA, the Level 5 course is designed for people with little or no English teaching experience.
  • Trinity CertPT (Certificate for Practising Teachers) - Trinity’s Level 6 is designed for teachers who have already been teaching for a minimum of six months. It aims to support teachers' further development and help them improve their teaching practice.
  • DELTA (Diploma in Teaching English to Speakers of Other Languages) - Cambridge’s provides professional development for teachers with at least one year’s experience. This level 7 qualification is also designed for those who want to progress into more senior roles such as head of English and teacher training.
  • Trinity DipTESOL (Diploma in Teaching English to Speakers of Other Languages) - Trinity’s is designed for teachers who have reached a stage in their career where they’d like to progress to a more senior level. Like the DELTA, it’s an internationally respected level 7 qualification for experienced TEFL teachers.
  • Master’s degree - Master’s studies in English Language Teaching, TESOL, or applied linguistics, are great options to reach a more senior level in your career. Most people take them to become a director of studies or reach a management position.
  • Specialized courses - If there’s an area of teaching that you’d like to specialize in, plenty of short courses cover a range of topics. These include teaching online, teaching with technology, teaching business English and teaching very young children. Check out , or to see what they offer.

If you’re unable to take a formal course, sharing ideas with colleagues is a great way to create professional development opportunities. You could exchange lesson plans and ask for feedback or input. There are plenty of podcasts, webinars and social media groups for teachers where you can find great tips and ideas from fellow teachers worldwide.

Whichever route you decide, remember that learning is a lifelong journey – not only for your students but for yourself too! There are always new things to discover that will help you develop as a teacher.

    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 ɫèAV. 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.
