Most articles about becoming an ALT focus on practical advice. They explain what to pack, how to find an apartment, how to navigate culture shock, or what kinds of classroom activities work well with students.
All of those things have their place. And I have given much of that advice myself over the years.
Looking back, however, the things that most shaped my experience as an ALT were not practical at all. They were structural. They were the assumptions I brought with me about schools, teaching, communication, and how organisations function.
The interesting thing is that none of these realities were hidden. They were visible every day. I simply lacked the experience and context to recognise what I was looking at.
Over time, many of the lessons I learned became the foundation of the previous articles in this series. They also explain why new ALTs often find themselves confused, frustrated, or surprised by situations that seem perfectly ordinary to those around them.
I Didn’t Understand That There Was No Single ALT Role
When I first became an ALT, I assumed I was entering a clearly defined profession.
That sounds obvious now, but it shaped many of my early expectations. I assumed there would be a reasonably consistent understanding of the role, a shared set of responsibilities, and broadly similar expectations from school to school.
Instead, I discovered that the ALT position exists in a space that is remarkably flexible. As I discussed in earlier articles on ESID (“Every Situation Is Different”) and the meaning of the word “assistant”, different schools often interpret the role in very different ways.
One school may expect an ALT to lead activities and contribute heavily to lesson planning. Another may view the ALT primarily as a language model or cultural resource. Some teachers actively seek collaboration. Others prefer to work independently. Even within the same school, expectations can differ from teacher to teacher.
At first, I interpreted these differences as inconsistencies. Looking back, I think it is more accurate to see them as a feature of the system itself.
Understanding this changes how you approach the job. Rather than searching for a universal definition of what an ALT should do, it becomes more useful to understand what your particular school expects and why.
I Didn’t Understand That Relationships Often Matter More Than Activities
Like many new ALTs, I spent a great deal of time thinking about lessons. I searched for activities, adapted worksheets, and worried about whether students enjoyed particular games. Those things matter, and good lessons are important. Yet some of the most significant factors shaping my experience had very little to do with lesson plans at all.
Over time, I realised that trust, communication, and reliability often shaped the role just as much as classroom performance.
The previous article in this series explored how evaluation often works during the first few months. One of the reasons this surprises people is that schools are frequently paying attention to much more than classroom performance. They are observing how an ALT communicates, how they respond to changes, and how they fit into the wider environment.
The longer I worked in schools, the more I realised that strong relationships often created opportunities that no lesson plan could. Teachers who trusted an ALT were more likely to share ideas, collaborate, ask for support, and gradually expand the role. In contrast, even a talented teacher can struggle if those relationships never develop.
For many ALTs, this is one of the most important lessons of all. The role exists within a network of professional relationships, not outside it.
I Didn’t Understand How Little Time Teachers Actually Had
One of the easiest mistakes for a new ALT to make is assuming that a lack of communication reflects a lack of interest.
A teacher gives a short reply. A planning meeting lasts only a few minutes. An email receives no response. A lesson suggestion seems to disappear into the void. From the outside, it can appear that nobody wants to collaborate.
What I gradually came to understand was that many teachers are simply operating under enormous time pressures. Alongside teaching, they are often responsible for club activities, homeroom duties, administrative work, meetings, student welfare issues, parent communication, marking, and a long list of other responsibilities.
One question I often ask Japanese teachers throughout the year is: “What percentage of your working time do you actually spend teaching or preparing lessons?” The answers are usually much lower than many ALTs expect. While exact figures vary, the broader point remains the same. A significant portion of a teacher’s working day is spent on responsibilities outside the classroom.
The conversation itself is often valuable. It demonstrates an interest in the realities of teachers’ work and frequently leads to a deeper understanding of the pressures they face. It also shows colleagues that you recognise their role extends far beyond delivering lessons.
This does not mean every communication problem can be explained by workload. Nor does it mean collaboration is impossible. However, understanding these pressures provides important context. Many of the behaviours that initially seem confusing begin to make more sense once you understand how schools actually function behind the scenes.
I Didn’t Understand That Team Teaching Is Not Self-Explanatory
When I first encountered the idea of team teaching, it sounded straightforward. Two teachers working together toward a shared educational goal.
In practice, the reality proved much more complicated.
Some teachers view team teaching as genuine collaboration. Others see it as a division of responsibilities. Some prefer detailed planning meetings. Others rely on improvisation. Some want the ALT to take an active role. Others prefer a more limited level of involvement.
The challenge is that many ALTs arrive with assumptions about what team teaching should look like, only to discover that the people around them may have very different expectations.
This is one of the most important aspects of the ALT role, and one of the most misunderstood. In the next article, I will explore this topic in much greater detail.
I Didn’t Understand How Long Understanding Takes
Perhaps the biggest misconception I had was believing that understanding would come quickly. I assumed that after a few months I would understand the system. Then I thought it would take a year. Then perhaps two.
The reality was very different.
The longer I stayed, the more I realised how much I had initially failed to notice. Schools operate through countless formal and informal systems, many of which only become visible over time. Expectations that seem obvious to experienced teachers may never be explained directly. Organisational habits that appear unusual at first often have historical or practical roots that only become clear later.
This process is not unique to Japan. Anyone working within a new institution or culture experiences something similar. What makes the ALT role unusual is that many people are expected to navigate these complexities with relatively little preparation or guidance.
Understanding develops gradually. It emerges through observation, conversation, mistakes, and reflection.
Looking back, most of the things I did not understand were not hidden from me. They were visible every day.
I simply lacked the context to interpret them.
That, perhaps, is one of the central challenges of ALT work. Success depends not only on teaching English, but on learning to read the environment around you.
One area where this becomes particularly important is team teaching. On paper, the idea sounds straightforward. In practice, it is one of the most misunderstood aspects of the ALT role. I will explore that in the next article.
