I am sorry the OT was so unprofessional. This is most certainly within the scope of practice for the OT and appropriate in the school environment.

I have also attached an article link that provides sample goals, measurements, and the appropriate links to professional standards. https://www.researchgate.net/profile/Deborah_Bruns/publication/264003906_Turning_Mealtimes_into_Learning_Opportunities_Integrating_Feeding_Goals_into_IEPs/links/00b4953c859d78360d000000/Turning-Mealtimes-into-Learning-Opportunities-Integrating-Feeding-Goals-into-IEPs.pdf
