It sounds like the tester hasn't figured out how to work with her. I suspect she feels it's better to meet several times instead of pushing through being upset. Of course, now poor experience with the arrangement is likely feeding anxiety over it all.
Can you contact the tester to get notice ahead of time which times she'll be coming?
Then you can prepare your daughter: Mrs. T is coming to do some more puzzles with you today during reading groups. These aren't like other things you've done in school. In your first grade class,you only see things that first graders are supposed to understand. These tests are going to ask you things that start easy and get hard, and they'll be hard even for a 3rd grader. If you don't know something, it's ok, because it's meant to get too hard. Just tell Mrs. T you don't know that yet.
You can tell the tester what your script has been so she can back you up and confirm it all for your daughter.
Poor dear, that sounds awfully stressful.
