Teaching Mixed‑Level Classes - Why It’s Hard and How to Make It Work

In this blog post, Distance Cert director and Cert IBET learning mentor Ben Dobbs reflects on a LinkedIn comment regarding what should be covered on initial teacher training course but isn't. Here, Ben offers some ideas and potential, if somewhat idealised, solutions and mitigation strategies.

In response to one of our recent posts on LinkedIn asking what teachers believe should be covered on courses such as CELTA but isn’t, Kaohsiung-based English Language Instructor Martin Cooke offered the following observation:

How to teach mixed ability groups. When I did the CELTA, the students were all grouped at roughly the same level but that's actually rare in many contexts. A good challenge for a new teacher would be to see how they work with groups where some learners speak near-zero English while others are highly fluent.

Martin’s comment is spot on and has had me thinking over the past few weeks since; if we reflect our own experiences as teachers, whatever our context, this would be very difficult to dispute. Walk into almost any English language classroom around the world and you’ll encounter, at some point, the ominous mixed-level group! One learner races through tasks, another struggles with basic structures and several sit somewhere in the middle.

Mixed-level classes are the norm rather than the exception, yet they remain one of the most challenging teaching contexts for TEFL professionals; however, the subject is never, to my knowledge, trained on initial teacher training courses.

What can be done in these contexts? To me, understanding why they are difficult is the first step while knowing how to work with them effectively is what transforms frustration into progress. It is also worth admitting to ourselves as teachers and trainers that there is never going to be a perfect or ideal solution to mixed-level classes; of course, the more extreme the difference, the greater the difficulties become.

Mixed‑level classes stretch a teacher’s planning, monitoring and differentiation skills more than almost any other teaching situation. The core difficulty lies in the uneven distribution of language knowledge, confidence, processing speed and learning behaviours. Stronger learners may dominate discussions, finish tasks early, or become bored if the pace feels slow. Weaker learners, meanwhile, can feel overwhelmed, anxious or left behind. This imbalance affects not only language outcomes but also classroom dynamics, motivation and the teacher’s ability to maintain a coherent lesson flow. This can also affect the motivation and confidence of the teachers.

We can be optimistic and say that mixed‑level classes also offer unique opportunities. When managed well and presuming the culture and systems allow, they create good conditions for peer support, authentic communication and collaborative learning. We could say that level differences are a key area of classroom diversity and a diverse team with differences managed and utilised is always going to outperform a homogenous team or one that attempts to remove these differences. The key is not to “fix” the level differences (that is very likely impossible) but to design lessons that, at least on paper, embrace them.  

One of the most effective strategies is tiered task design, where all students work with the same theme or skill but at different levels of complexity. For example, in a lesson on giving opinions, beginners might use sentence frames (“I think… because…”), while advanced learners develop extended arguments or evaluate multiple viewpoints. Everyone participates but no one is held back. There is a big “however” and that is the politics that this can create as to who is in which group and how personal pride is, if at all, affected.

Another powerful approach is flexible grouping. Rather than keeping students in fixed pairs or teams, vary the grouping depending on the task. Homogeneous groups allow weaker learners to work at a manageable pace and stronger learners to stretch themselves. Heterogeneous / diverse groups encourage peer teaching, modelling and natural scaffolding.

Open‑ended tasks are also a teacher’s friend in mixed‑level settings. Activities such as discussions, problem‑solving tasks, role‑plays, simulations and project work allow learners to contribute at their own linguistic level and for learners to collaborate and support each other presuming the culture is supportive and not overtly competitive. Because there is no single “correct” answer, students can personalise the language, negotiate meaning and push themselves without feeling exposed. This reduces anxiety for weaker learners and increases challenge for stronger ones. This needs to be supported by frequent and positive affirmative teacher feedback about collaboration, support and other critical success factors beyond only language skills and systems.

Classroom management also plays a crucial role in mixed level classrooms. Clear instructions, visible task stages, and predictable routines help weaker learners stay oriented. Early finishers need meaningful extension tasks as opposed to “busy work”, such as adding detail, improving accuracy, developing the graphical aspects of a presentation or preparing to report back. Meanwhile, the teacher’s monitoring becomes strategic: offering targeted support to those who need it while nudging stronger learners toward greater complexity and autonomy.

Finally, mindset matters. Mixed‑level classes become far more manageable when teachers shift from a “one pace for all” mentality to a “multiple pathways to success” approach. Differences in the pace of progress are, as we know, the reality of language acquisition. Though no plan survives the collision with reality of a dynamic classroom, when lessons are designed with flexibility, choice and layered challenges, mixed‑level groups can stop feeling like a compromise and start functioning as dynamic, collaborative learning communities.

Mixed‑level classes will always require more planning and more responsiveness in the moment. But with thoughtful task design, purposeful grouping and a supportive classroom culture, they can produce some of the richest learning experiences for teachers and learners.
