How do you define and map a construct for assessment purposes?
What the interviewer is testing: Tests understanding of construct definition.
Key terms: construct, construct map, validity
Defining a construct starts with the specification but goes deeper. I ask: what exactly does competent performance look like? For each construct, I identify the intended knowledge (what learners must know), intended skill (what learners must be able to do), and intended behaviour (how learners must conduct themselves). I then map each to the qualification level using level descriptors to ensure the demand is appropriate. I identify what evidence would demonstrate the construct, what irrelevant barriers might prevent learners from showing their ability, and what validity risks exist. The construct map then guides method selection - ensuring the assessment method genuinely tests the construct, not something else.
I just read what the specification says and write questions about it.
Likely follow-up: How would you know if your construct definition was wrong?
