I don't know the second tool you list but I can share that my PG w Dysgraphia and Dyspraxia kiddo had a Beery VMI with these scores and corresponding %tiles:
VMI Standard score of 45= 2nd percentile (Very Low)
Visual Perception of 93= 31st percentile (Average)
Motor Coordination of 69= 15th percentile (Very Low)
The first number tells overall ability for visual motor and the other two are to tease apart where the challenge lies. My son showed more motor than visual perception challenge.
I hope that gives you something to work with. If you can find an OT forum of some sort you may be able to post your question there and learn more.
I hope your meeting goes well! Take a deep breath, ask lots of questions, and take good notes. Then let us know how it goes!
