Teaching English to adults is not teaching teenagers at a slower pace. The student has expertise you can use, an ego you have to respect, and a week that keeps eating the homework. Design around those three facts and most classroom problems disappear before the lesson starts.
Teaching English to adults breaks the moment the material talks down to them
Open a random worksheet sold for teaching English to adults and you will often find cartoon clip art, a text about a family trip to the zoo, and a discussion question asking whether the student likes travelling. The student is a project manager with two children and a mortgage. She notices.
The damage is not offence, it is disengagement. An adult who decides the material is beneath them stops investing, answers in four words and privately concludes that their English is not improving. That conclusion is correct, and it has nothing to do with their ability. Teaching English to adults starts with material an adult would read on their own.
Your student is an expert in something, so let the lesson use it
Anyone teaching English to adults is teaching somebody who knows a subject better than they do. Logistics, radiology, tax law, warehouse rosters, something. That expertise is free content, and it changes the direction of the lesson.
Ask the accountant whether AI will take the boring half of her job, or the nurse whether the wellness industry helps anyone, and you get opinions with detail behind them. The language then has a job to do, since the student needs it to explain something they actually understand. This is why we build lessons around a question rather than a grammar point, an approach explained in Talking Point.
The gap between Tuesday and Tuesday is your real opponent
A teenager sees English five times a week. Your adult student sees it once, then works for six days. Anything introduced on Tuesday and never met again is gone by the following Tuesday, no matter how well it was taught.
Recycling has to be built into the material rather than added by goodwill. The same eight expressions should appear in the input, in a controlled exercise, in the speaking task and then again in a listening after the lesson. That is the whole reason our full lessons ship with a podcast bonus, and why Language Boosts exist as short standalone materials for functional language. When teaching English to adults, repetition in new contexts beats volume every time.
Correcting a forty year old is a different act
Correction with teenagers is routine. In teaching English to adults it touches status, because your student manages people all week and is now being told they got a preposition wrong in front of a stranger.
Nothing here argues for letting errors pass. It argues for timing and framing. Correct in writing during the task, on the board after it, without names attached. Reformulate rather than label: repeat the sentence correctly in your own answer and move on. Save the direct interruption for errors that block meaning, and let the rest wait four minutes. Teachers who get this right keep adults talking, and adults who keep talking improve.
Motivation is never general, it is a meeting on Thursday
Ask an adult why they are learning and you get a vague answer about wanting to be fluent. Ask what they had to do in English last month and you get something precise: a client call, an interview, a conference, a difficult email to a supplier.
The second answer is the syllabus. Teaching English to adults works when the material points at a real situation the student will face within weeks, which is also why Speaking Challenges with a single mechanic land so well. A task that ends in convincing someone maps directly onto a meeting where they need to convince someone.
One to one is a different format, not a smaller class
Most material published for teaching English to adults assumes a group. Half of adult teaching happens with one student and a screen, where every pair activity has to be rebuilt on the spot.
Three adjustments do most of the work. Take a position openly and tell the student it is a role, so disagreement stays comfortable. Ask for detail rather than length, because "why did that not work" produces more language than "tell me more about it". Watch your own share of the talking, since in one to one lessons it grows without anyone noticing. Short materials with a built in imbalance, such as Quick Talks, are easier to run in this format than open discussion.
The lesson has to survive a cancelled week
Adults cancel. A deadline moves, a child gets ill, a flight is delayed, and your carefully sequenced ten week course loses its third and seventh lessons.
Design for it, because teaching English to adults means planning around absence rather than being surprised by it. Make each lesson complete in itself, with its own topic, its own language and its own outcome, so a missed week costs one lesson rather than the thread. Thematic sets like Collections give continuity without dependency, since the lessons share a theme but not a sequence. This is unglamorous planning, and it is the difference between a course that survives a busy autumn and one that quietly stops.
At eight in the evening you are competing with a phone
Most adult lessons happen at the worst hour of the day, after work and before sleep. The student has already made four hundred decisions since morning and has nothing left for a gap fill. Energy, not ability, decides how that hour goes.
Two things help more than any activity. Start with something the student reacts to rather than produces, because reacting costs less than generating and gets the mouth moving anyway. Then put the hardest task in the middle, not at the end, since attention drops sharply in the final ten minutes and that is a poor moment for a debate.
The third thing is honesty about volume. Teaching English to adults in the evening means covering less material than the plan says, and covering it properly. A tired student who spoke for twenty minutes learned more than one who was walked through five exercises in silence.
Levels matter less than the level of the topic
A B1 student can discuss surveillance, pricing tricks or overwork, provided the input is short and the language is handed to them first. The Council of Europe's CEFR Companion Volume describes ability through what a learner can do in real situations, and Cambridge English sets out the same six point scale from A1 to C2.
Nothing in either document says an adult at B1 must talk about hobbies. Simplify the text, not the subject. Materials tagged by level, such as our B2 materials, let you keep an adult topic while matching the language load to the group.
What to put in front of your adult class next week
Take one full lesson from Big Talks and teach it unchanged, without adapting anything in advance. The lesson on productivity asks whether working harder makes anyone more productive, which every working adult has a private opinion about. Then compare how much your students said against your usual Tuesday.
That comparison is the only honest test of whether a material is doing its job. Fifteen minute materials sit in Quick Talks, everything is browsable in the shop, and the practical notes for people teaching adults explain how the formats fit together. For wider professional reading on teaching English to adults, TESOL International Association publishes standards and development material that go well beyond any single lesson.
