Prepare for the CELTA - Certificate in English Language Teaching to Adults exam with our free practice test modules. Each quiz covers key topics to help you pass on your first try.
These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.
Question: What is a phoneme in English linguistics?
Answer: B. The smallest unit of sound that distinguishes meaning
Explanation:
The correct answer is that a phoneme is the smallest unit of sound that distinguishes meaning. Changing /p/ to /b/ turns 'pin' into 'bin', so those two sounds are separate phonemes in English.
A written symbol representing a sound is wrong because it describes a phonemic symbol or a letter, not the sound itself. A unit of grammar that changes verb tense is wrong because that describes a morpheme or an inflection, which belongs to grammar rather than sound. A category of vowel sounds only is wrong because phonemes include consonants as well as vowels.
Rule to remember: a phoneme is about sound and meaning. If swapping a single sound changes the word, you are looking at different phonemes.
Question: What is a lesson procedure?
Answer: C. The sequence and method of delivery
Explanation:
The correct answer is the sequence and method of delivery. A lesson procedure is the step-by-step plan of what the teacher and learners will do, stage by stage, and how each stage will be run.
The school's curriculum is wrong because the curriculum is a wider programme of study across many lessons, while a procedure covers a single lesson. The teacher's resume is wrong because it is a document about the teacher's career, not about the lesson. Student feedback forms are wrong because they collect opinions after teaching and are not a plan for delivery.
Rule to remember: the procedure is the 'how and in what order' part of a lesson plan. Aims say why, and the procedure says how you will get there.
Question: What is a weak form in English pronunciation?
Answer: B. The reduced, unstressed pronunciation of function words in natural speech
Explanation:
The correct answer is the reduced, unstressed pronunciation of function words in natural speech. Words such as 'and' often become /ənd/ or /ən/ in connected speech, and this is normal rather than careless.
A mispronounced word that learners produce is wrong because weak forms are standard features of native-like speech, not errors. A grammatically incorrect sentence structure is wrong because weak forms concern sound, not grammar. A low-frequency vocabulary item is wrong because weak forms usually affect very common function words such as articles, prepositions and auxiliaries.
Rule to remember: content words tend to carry stress, and function words are often weakened. Learners who only know the strong forms can find fast speech hard to understand.
Start by reading the official Cambridge English CELTA pages so you know what the assignments and the assessed teaching practice ask of you. Then use our practice sets to find your weak areas before you rely on any one topic.
During the course, apply what you practise to your lesson plans and written assignments, and ask your tutors for feedback.
