Cambridge TKT common mistakes
Cambridge TKT · Understand the traps and how to avoid them.
Revising the glossary as a word list and then picking whichever term looks familiar, so near-neighbours get swapped (approach / method / technique, PPP vs test-teach-test, learner training vs learner autonomy, controlled vs freer practice).
Terms are memorised as single words with a one-line gloss, but the exam tests discrimination between them inside a described classroom context, so recognition without contrast is not enough.
What to do instead
Revise in contrastive pairs: for each pair write your own definition, a one-line classroom example, and a counter-example that would NOT fit. Check both against the official glossary wording and make the pair, not the single term, your unit of revision.
Classifying every learner mistake as 'an error to correct now' - calling a slip a fossilised error, calling L1 transfer overgeneralisation, and choosing immediate correction in a stage whose aim is fluency.
The distinctions (slip / error / attempt; developmental vs interference) only make sense in context, and in real teaching the default is to correct everything on the spot.
What to do instead
Build a three-column table: evidence in the item -> label -> appropriate teacher response. Practise on two-line transcripts and first decide whether the stage aim is accuracy or fluency; the correction decision follows from that decision.
When asked what a teacher is focusing on in a stage, answering with the grammar label (e.g. 'the present continuous') when the item clearly shows learners practising making requests or the teacher checking understanding of meaning.
Candidates hunt for a target structure and stop there, treating form, meaning and function as interchangeable rather than as three separate possible focuses.
What to do instead
For any short extract, write three candidate focuses (form / meaning / function) and then select the one the teacher's behaviour actually evidences. Learn function labels ('apologising', 'declining an invitation') and the wording of concept-checking questions as their own category.
Selecting or writing aims that are really procedures ('do a survey', 'play a game') or vague hopes ('students will learn vocabulary'), and treating main, subsidiary and personal aims as interchangeable.
Aims are rarely written out in everyday teaching, and candidates assume the 'main aim' is the biggest or most enjoyable activity rather than the primary learning outcome.
What to do instead
Use the frame 'By the end of the lesson, learners will be better able to + verb + language/skill' for the main aim, and label the others explicitly (subsidiary = secondary outcome, personal = teacher development, procedure = what happens in the room). Re-label one short lesson plan a week until the categories are automatic.
Choosing the liveliest or most communicative activity rather than the one that fits the stated level, age, class size, time, equipment and position in the lesson sequence.
Teachers adapt from habit and judge tasks by appeal; under time pressure the constraints in the stem get skimmed and the 'best practice' option looks right regardless of fit.
What to do instead
Before reading the options, underline and list every constraint in the stem (e.g. '30 learners, 15 minutes, no projector, first lesson'), then test each option against the list and reject any that breaks even one constraint.
Misidentifying teacher roles and interaction patterns from behavioural descriptions - calling monitoring 'facilitating', calling a teacher-fronted demonstration 'group work' or 'T-Ss', or confusing open pairs with closed pairs.
Roles are learned as abstract nouns with no observable behaviours attached, so any supportive-sounding role appears to fit any supportive-sounding teacher.
What to do instead
Add an 'observable behaviour' column to each role (controller = directs, all eyes on teacher; monitor = circulates, listens, does not intervene; resource = available on request). Label two-line scenarios and draw an arrow diagram of the interaction pattern for each.
Choosing a feedback or grouping technique that reflects personal preference rather than the aim of the stage - echo correction during a fluency task, teacher nomination in a pairwork fluency stage, long teacher explanation in a discovery stage.
Candidates default to the technique they use themselves, but the item asks what is appropriate given the aim that has been stated in the stem.
What to do instead
For each management technique note 'works when...' and 'fails when...' (e.g. delayed correction works when the aim is fluency). Read the stated aim first, decide accuracy vs fluency and teacher-centred vs learner-centred, then filter the options against that decision.
Equating CLIL with 'teaching a subject through English' and then missing the language dimension - no BICS/CALP distinction, no language of / for / through learning, no cognitive level (LOTS/HOTS), and 'scaffolding' read as 'simplifying the text'.
CLIL items assess a dual content-and-language focus that most single-subject teachers have never been trained in, so the language demands stay invisible unless they are explicitly named.
What to do instead
Plan every CLIL activity in three columns: content objective / language of learning, language for learning, language through learning / cognitive level. Then practise distinguishing scaffolding (temporary support that is withdrawn) from simplification (task made easier) with one concrete example of each.
Treating 'young learners' as one homogeneous category and answering with adult or teenage classroom logic - long teacher explanations, grammar metalanguage, silent written work, expectations of homework and self-study - instead of routines, play, TPR, short activity cycles and multi-sensory presentation.
Most candidates have taught only one age band, so they generalise from it; items usually state the age (e.g. 'a class of 6-year-olds') and expect the candidate to notice and use it.
What to do instead
Learn the age bands and their characteristics (roughly 5-7, 8-11, 12-14: concentration span, literacy, abstract reasoning, need for routine and movement). For each activity type note the minimum age at which it works and why, and check the stated age before answering.
Choosing formal written tests, accuracy marks or heavy on-the-spot correction as the answer for young learners, and overlooking praise, continuous observation and concept-level rather than metalinguistic feedback.
Candidates transfer assessment habits from exam-oriented teaching, while YL items reward low-anxiety, oral, continuous and constructive feedback.
What to do instead
Build a table of purpose (check understanding / encourage / diagnose) against age-appropriate technique (thumbs up, choral drilling with praise, observation checklist or portfolio, delayed correction of a recurring error). Reject any option that depends on grammar terminology or raises learner anxiety.
