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.

  • What’s it like to teach English in Nepal?

    By
    Reading time: 3 minutes

    Anandi Vara was trained in teaching English in Kathmandu, Nepal before teaching at a monastery in Pokhara. There she taught students ranging from six to 10 years of age, both in groups and individually. Here she reveals the lessons she learned during her time there– including how to avoid being perturbed by a cockroach attack.

    Whatever you do: don’t freak out

    It just makes everything worse. It’s easy for things to get overwhelming – a sense that can be made worse by the feeling of homesickness, especially if it’s your first time living abroad – but thinking rationally, and getting to the source of what’s causing the worry, usually helps. It’s important, as you don't want to share your fear in lessons because you’re the teacher and need to show confidence.

    This was, however, tested to the limit when I had a cockroach dangled in front of my face. It took all my strength to stay calm. I gave an unimpressed look, thereby establishing myself as the figure of authority, which seemed to work.

    Be aware of cultural traditions

    It is important to remember that every country has its own traditions. I was teaching in a monastery, so I made sure to wear respectful clothing, even in the face of soaring temperatures. The more I learned about the Tibetan culture, the more fascinated I became by it. The students taught me how to write my name in Tibetan and the meaning behind it. I learned about Tibetan history and Tibetan culture.

    I also found that the more I showed willingness to learn about the Tibetan culture, the more I bonded with the students, so that when it was time to teach, the students were more cooperative in lessons, engaging and participating more.

    Teaching is two-way learning

    There is so much I learned teaching abroad, both in the classroom and out. Making mistakes as you begin is only natural, but it’s whether you can learn from these mistakes that counts. No two students are ever the same so it’s a constant process of learning as you go. As a result, I learned about the environment I was in – from traditional prayer ceremonies to the Tibetan alphabet– and about myself, notably organizational skills and a renewed curiosity about the English language.

    Be Flexible

    Sometimes it doesn’t matter if you’ve planned your lesson down to the smallest detail – if it doesn’t take, then it doesn’t take. I was only 10 minutes into a lesson once and I could tell that I was beginning to lose the students’ attention. Not only did it show that they were uninterested, it also distracted me from what I was doing. It was at this point that I threw out my existing plan and tried a whole new lesson: I had the students up on their feet and engaging with each other and, although completely improvised, it was very successful.

    Patience is a must

    During my one-on-one mentoring session, my student seemed to have no motivation. He wasn’t learning as well as the other students and had therefore given up. No matter what I tried, he refused to cooperate, but I didn’t let it put me off. I kept trying different methods until finally finding one that he responded to. I made sentence structuring into a game. It wasn’t anything fancy and consisted of scraps of paper with words written on them.

    Although it took a lot of time to find the right angle, it was worth it because he soon realised that although it might take longer for him to pick things up, he would eventually get there and have a greater sense of accomplishment.

    How to use flipped learning to support your learners

    What is flipped learning?

    To understand better what flipped learning is, first let’s see how it differs from blended learning, a term with which it is often confused.

    Blended learning is a way of teaching that combines face-to-face classroom teaching with online resources. We freely use online resources to create a more personalized learning experience.

    Flipped learning is a little different. As the name suggests, it "flips" a traditional lesson. It tells us exactly which stages of the lesson should go online. In a flipped learning class, all of the more traditional aspects (also called "study stages"), are completed online and the homework (also called "application stages") comes into the classroom.

    Let’s look at an example.

    A typical receptive skills lesson normally has six stages:

    1. Lead in
    2. Set context
    3. Pre-teach vocabulary
    4. Gist task
    5. Detailed task
    6. Follow up

    With a traditional teaching model, we do the first five stages in class and set the last one for homework. With flipped learning there are a few ways to tackle these stages, but a basic model would look like this:

  • Precision teaching with AI: Aligning GSE objectives with generative AI for targeted materials

    By
    Reading time: 4 minutes

    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 ɫèAV, 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

    • : for exploring and selecting level-appropriate learning objectives
    • : for generating customizable teaching content
    • GSE Smart Lesson Generator: an AI-powered lesson creation tool developed by ɫèAV that uses the GSE framework to automatically generate high-quality activities and lesson plans
    • Google Docs or Word: for editing and organizing your materials before class

    Confidently transforming English teaching

    Combining Generative AI with the Global Scale of English allows teachers to design materials that are both fast and focused. The GSE provides the structure; AI provides the speed. Together, they offer a sustainable solution for personalized English instruction that respects both learner needs and instructional quality.
