Hey, if it ain't broke, don't fix it, right? The shirt-grabbing is working for her.

My experience is much more with Special Education, where federal law dictates that information be gathered from a variety of sources, and that educational decisions be made by a team that first reviews that information.

Making a decision before the meeting, based on a single score, or based on available resources are all mistakes that could land a school in a world of trouble under IDEA and state laws. The laws governing gifted education are much less ironclad, but I would consider a similar approach to those educational decisions to be best practices, at the very least.
