WriteTrax

Screen for handwriting difficulties in under 60 seconds. WriteTrax gives teachers an instant, evidence-based handwriting assessment from a single photograph —
Photograph a student's handwriting sample. WriteTrax analyzes it across five clinical dimensions and returns a complete assessment with scores, root cause identification, and classroom-ready intervention strategies. Export a professional PDF report in one tap.
HOW IT WORKS

Select a student from your class roster
Photograph their handwriting sample
Receive a complete assessment in under 60 seconds
Export a professional PDF for documentation

Student names never leave your device. No cloud database. No student records transmitted.
FIVE-DIMENSION SCORING
Every assessment scores the sample across five dimensions aligned with established OT assessment frameworks:

Letter Formation — shape accuracy, reversals, stroke direction
Line Alignment — baseline contact, drift, ascender placement
Spacing — letter gaps within words, spacing between words
Sizing — x-height consistency, proportional accuracy
Slant Consistency — angle uniformity across the sample

Each dimension is scored 0–100 and weighted by grade level — a Pre-K assessment applies developmentally appropriate expectations, a high school assessment applies different ones.
ROOT CAUSE IDENTIFICATION
WriteTrax identifies the primary pattern driving the difficulty:

Motor/Graphomotor — tremor, fatigue, pencil control
Knowledge/Learning — systematic reversals, letter malformation
Attention/Executive Function — inconsistent errors, quality variance

Root cause drives the intervention recommendations. A motor difficulty gets different strategies than a knowledge gap.
PROFESSIONAL REPORTS
Every assessment generates a complete PDF including:

Overall grade-adjusted score
All five dimension scores with rationale
Root cause attribution with supporting evidence
Three-paragraph professional narrative
Three to four grade-appropriate intervention strategies

PROGRESS TRACKING
Assess the same student over time and watch scores change. WriteTrax tracks every assessment and displays progress charts across all five dimensions. Class-level reports show score distributions and root cause patterns across your entire roster.
BUILT FOR EVERY CLASSROOM
WriteTrax supports Pre-K through 12th grade across three handwriting styles — printing, cursive, and joined italic. Whether you teach kindergarten, manage a special education caseload, or work as a school-based OT, WriteTrax gives you a documented baseline in under a minute.
