These are simplified, interactive examples inspired by the 1911 Binet list (as summarized by Terman). They are historical demonstrations only and are not diagnostic.
What to do: Work through each task in turn — click the relevant elements, type answers, or choose from dropdowns. A running score appears at the bottom.
