Thanks for the feedback. This year the GT pull-out is for an hour every day for 10 days and then they have 20 days with no pull-out while the teacher goes to the other schools. Each 10-day unit has an enrichment theme during which they do various projects related to the theme. Their work is completely unrelated to classroom work and, like I said, they are always responsible for all the content and assignments that they miss in the regular classroom while they are gone. And, if they miss the pull-out class because they were sick or whatever, the teacher does not seem to go back to explain what was missed.
Anyway, I didn't bring it up when I met briefly with the teacher a month or so ago, but it was nagging at me. So thanks for the input!
