When a child lacks a skill, you can either teach the skill, provide accommodations, or do both. Handwriting is a prime example of this, often overlooked by many schools and parents.
What I mean is, handwriting does not have to be ‘either, or.’ In that, the child either learns to write or use voice-to-text (or another form of AAC). You can, and should, do both.
Children not only learn to read more quickly when they first learn to write by hand, but they also remain better able to generate ideas and retain information.
Improved handwriting helps students better recognize and write critical letter features, revealing a strong connection between the hand and brain's neural circuitry.
Numerous assistive technology options, including both low-tech and high-tech solutions, are available. If you're including Handwriting Goals in your IEP, here are some initial ideas to consider.
Remember that before a child can work on handwriting, they have to have the pre-skill of letter recognition. I have a separate list of letter recognition goals.
