EG
I could construct a fairly valid assessment of a 6yo’s times-tables understanding by testing them on all their times-tables.
But if I want to gauge the understanding of a 16-year-old, I can't easily test them on everything they should know... this would take days.

Finally, the stakes we attach to any assessment should be in proportion to the validity of our inferences.
Otherwise, it just ain’t fair.

• Learning is invisible. Assessment is an attempt to make it more visible
• Validity refers to how well any inference we make from an assessment reflects the reality of student understanding
• We should avoid attaching high stakes consequences to low validity inferences
