What Is Concept Checking and Why Do Employers Care?

Why "Do You Understand?" Doesn't Work

Here's a scenario you'll recognise from your own experience as a learner: a teacher or trainer explains something, asks "Does everyone understand?", a few people nod, and the class moves on. Three tasks later, it becomes clear that at least half the room didn't understand at all.

Why does this happen? Because "Do you understand?" is an anxiety question rather than a comprehension question. Students — particularly in cultures where admitting confusion is socially costly — will almost always say yes regardless of their actual comprehension. The question measures social confidence and politeness, not conceptual understanding.

This is the fundamental problem that concept checking questions (CCQs) solve.

What Concept Checking Questions Are

A concept checking question (CCQ) is a question specifically designed to verify that a student has understood the meaning of a language item — not just whether they can reproduce the correct words, but whether they've grasped the underlying concept.

Good CCQs are:

• Short and accessible: Answerable with yes/no, a number, or a single word
• Concept-dependent: The correct answer is only possible if the concept is understood
• Non-linguistic in form: They avoid asking students to reproduce or translate the target language (which tests memory, not comprehension)
• Multiple: A single CCQ rarely confirms understanding reliably; 2–3 CCQs together are more robust

Poor "concept checking":

• "What does 'used to' mean?" (Tests metalinguistic knowledge, not concept understanding)
• "Can you translate 'I used to live in London'?" (Tests translation, not concept)
• "Do you understand the present perfect?" (The classic failure question)

An Example With the Present Perfect

Target language: "I have been to France." Concept: An experience that happened at some point before now (specific time not stated or important).

Good CCQs:

• "Did this person go to France?" (Yes — confirms basic past event)
• "Do we know when they went?" (No — confirms the indefinite time aspect)
• "Have they finished the trip?" (Yes — confirms it's a completed experience)
• "Are they talking about a specific moment in the past?" (No — confirms contrast with simple past)

A student who answers all four correctly almost certainly understands the concept. A student who gets "Did they go to France — yes" but answers "Are they talking about a specific moment — yes" has revealed a specific misunderstanding that the teacher can now address.

Why TEFL Employers Ask About CCQs

CCQs appear in virtually every professional TEFL interview for good reason: they function as a proxy for the entire question of whether you've engaged seriously with your TEFL training.

Understanding CCQs requires:

1. Understanding that comprehension checking is distinct from elicitation
2. Knowing why "Do you understand?" fails
3. Being able to construct questions at the right level of accessibility
4. Understanding the difference between testing concept and testing form

A candidate who can demonstrate genuine understanding of CCQs — by explaining the principle clearly and providing a spontaneous, well-constructed example — signals to the interviewer that they've actually engaged with their TEFL methodology training rather than merely completing the hours.

A candidate who says "I'd ask students if they understand" signals the opposite.

CCQs in the Classroom: When to Use Them

CCQs are most valuable at the checking stage of the Presentation-Practice-Production (PPP) model — after you've introduced a new language item and before students are asked to produce it. Using CCQs at this point:

• Identifies specific misunderstandings before they become embedded errors
• Allows you to re-teach or clarify before students practise the wrong thing
• Signals to students that genuine understanding is expected, not just copying
• Creates a more interactive lesson structure than pure teacher presentation

They can also be used during or after practice activities when you notice a pattern suggesting a specific concept hasn't landed. Rather than interrupting individual students, well-timed whole-class CCQs can address shared misunderstandings efficiently.

Common Mistakes in Concept Checking

Checking form instead of meaning: "What's the verb form in this sentence?" checks grammar knowledge, not the concept.

Asking yes/no questions that can be guessed: Students have a 50% chance of guessing the right answer to a single yes/no question. Use 2–3 CCQs to create a pattern that requires genuine understanding.

Making CCQs harder than the target language: A CCQ that uses more complex vocabulary than the language item itself creates a new comprehension barrier.

Using CCQs as tests rather than checks: CCQs should feel conversational and supportive, not formal and evaluative. The goal is to identify and address misunderstanding, not to catch students out.

Practical Preparation for Your Interview

Before your TEFL interview, prepare CCQs for 3–4 common language items you might be asked about:

• A grammatical structure (e.g., present perfect for experience, third conditional)
• A functional phrase (e.g., making suggestions: "Why don't we...")
• A piece of vocabulary with potential conceptual confusion

Being able to produce these spontaneously in an interview — saying "I'd check with a couple of CCQs: 'Did this happen in the past?' and 'Do we know exactly when?'" — demonstrates exactly the level of methodological engagement that experienced interviewers are looking for.
