KHA is A brief, standardized assessment that captures important underlying movement data, giving clinicians and educators insight into learning, development, and aging

Standardized for Validity

Every KHA assessment follows the same protocol. The administrator uses identical language, instructions, and pacing with each participant. This standardization ensures:

• A level opportunity for every participant to perform at their best

• Valid comparisons across individuals and over time

• Reproducible results that hold up to scrutiny

• Removal of human scoring bias

Standardized assessment ensures that what is being measured is the participant's actual performance, not variation in how the test was given or interpreted.

The Assessment Experience

The participant is seated at a table or desk in a quiet space. The administrator verifies age and handedness, then provides an iPad and Apple Pencil.

The assessment includes two types of tasks:

Shape Tasks -The participant copies basic shapes as displayed. These tasks capture fundamental motor control: how the hand moves, how pressure is applied, and how smoothly lines are executed.

Handwriting Tasks -The participant completes age-appropriate writing tasks. These are timed, but the timer is not visible to the participant. Writing tasks capture the integration of motor control with cognitive demands - the real-world act of putting thoughts on paper.

Total time: typically 8-10 minutes of active assessment.

What's Happening in the Background

While the participant writes, KHA captures thousands of data points per second, with each stroke analyzed across multiple dimensions:

• How fast the pencil moves

• How hard it presses

• How smoothly it travels

• How long it pauses

• How its use is organized in space

• How consistent it remains across the task

These raw measurements are processed through specialized analysis engines, compared against age-appropriate normative data, and synthesized into a comprehensive performance report for the administrator. Additional proprietary components are working behind each screen, customized to capture the data vital to understanding how the individual is performing on each task.

The participant sees shapes and letters; the administrator receives objective insight into motor performance.

After the Assessment

Results are calculated immediately and transmitted securely. The administering educator or clinician receives a detailed report with:

• Individual metric performance

• Age-normed comparisons

• Composite scores across performance domains

• Performance characteristics within and outside the normative reference range

• Visual representations of the handwriting sample with legibility and accuracy scores

Eliminating subjective interpretation of legibility, accuracy, and visual motor metrics. For those needing clear progress-monitoring data, the ability to show strengths and areas of growth for individual students, clients, and participants.
