Every teacher's expertise,
for every student.
Create personalised learning materials for every student with developmental disabilities or delays.
Name, email and role — done in seconds.
The lesson ends,
but the preparation doesn't.
Every student needs different materials, and existing sets rarely work as they are — so teachers spend the hours outside the lesson getting ready.
“In the beginning I really made learning materials day and night.”
“I want to build materials from the objects and people around a child, matched to their daily life.”
“Published sets get difficult too quickly. The steps in between end up being made by the therapist.”
“When a family wants to try it at home, I usually make two sets of materials and send one over.”
Translated from interviews conducted in Korean.
The workflow of the field, as it is.
Make the materials, record and read the performance, and carry the classroom's learning home.

1Deselect and the dotted line goes — the number badges stay. The activity is done.
Not just a record kept —
something to plan the next session from.
Beyond accuracy, we look at recurring errors and confusable types, and show the basis for deciding what to do next.

01
We don't show results alone
The basis for the judgement comes with it.
Rather than accuracy and a recommendation on their own, you can see the repeated errors and the confusable types behind them.
-
02
One result is not a conclusion
Signals appear once enough has been recorded.
When there isn't enough data we don't rush the judgement — we say plainly that it needs a little longer.
-
03
The decision stays with the teacher
Analysis is evidence for the next choice.
TeachPatch suggests a direction — move on, keep going, check — but the goal and the next session are the teacher's call.
“I'm building the tool I wished existed while working with my students, and sharing it with educators who make a difference every day.”

I've worked with children with developmental disabilities and delays, making materials and writing down what happened. TeachPatch began as a way to cut that repetition and show the evidence for the next decision sooner.
