Make the next step
relevant to the learner.

Assessment, Reporting, Recommendation, and Curation connect a learner’s developmental picture with purposeful practice.

A

Assessment

Combine observations and assessment signals to understand a learner’s starting point.

R

Reporting

Turn developmental patterns into insights that parents and educators can understand.

R

Recommendation

Identify what to work on and suggest a pathway relevant to the learner.

C

Curation

Select appropriate activities and refine practice as new information emerges.

How it becomes personal

Signals in context.
Practice with a purpose.

Observations and performance signals are organized around developmental indicators. Reporting makes patterns understandable. Recommendation and curation connect those patterns with activities that can be practised and reviewed.

Information collected before, during, and after support helps describe progress. It does not, on its own, prove that the intervention caused every change.

Explore FIST: how an activity can be personalized

Frequency: how often to practise.

Intensity: the challenge or demand of the activity.

Speed: the pace at which it is performed.

Time: the duration of practice.

Explore the data and developmental framework

Parentof reports 400 million learning and behavioral data points, 50,000+ longitudinal users, and a developmental framework spanning 1,500+ micro-abilities. These describe the company’s platform foundation. Individual evaluations use separate samples and measures.
