“Approach” describes how the instrument assesses this construct, not the specific items. We never reproduce proprietary test items.

Consensus window: 16mo–2.5y (all 2 instruments overlap).

“Does {child_name} bring {his_her} little successes to you — showing you something {he_she} built, or wanting you to watch a new trick?”

Follow-up: “Does {he_she} ask you to watch with words or just by pulling you over?”

Not yet

Doesn't invite you to share {his_her} discoveries

Emerging

Occasionally shows you things, but doesn't wait for a reaction

Developing

Shows things and waits for your response

Secure

Regularly calls out 'look!' or similar and wants your full attention

These moments feel small but they are social skill-building at its finest — responding warmly fuels more of them.

The same canonical item shows up on the curriculum page with prerequisites, activities, and full developmental context.
