Why is handwriting assessment important?

The ability to write letters is a critical milestone for school children. Poor handwriting can lead to below average performance throughout a child’s education. 6% of children (2.5M) have fine-motor challenges that can permanently limit handwriting and success in school.


Occupational therapy is very effective in helping young children improve those fine-motor skills, but identifying which kids need therapy is a challenge. Existing assessments are time-consuming and subject to interpretation, so not all kids with fine-motor delays are identified or even tested.


Our Progress and Plan

  • 2018: NIH STTR Award to develop and de-risk

  • 2019: Developed 1.0 iPad app

  • 2019-2020: Validated in study of 54 children at WUSTL

  • 2020: Completed 2.0 version of STEGA, ready for OT and school use

PlatformSTL will enhance, further validate, and scale STEGA as a handwriting assessment for schools and OTs.
