I'd guess there's something going on, like a learning issue, anxiety, sensory, etc. I'd get an evaluation done as folks have said and go from there. My heart goes out to you--my daughter has outbursts, too, and we're on this same road right now. She's also in school because I had a high needs baby. But she held it together at first, and it seems to be more of an issue in 2nd/3rd. I wish we'd had a more communicative teacher and gotten started on the eval last year. So I would advise go for it. DD's behavior seemed to be less often an issue, so it's more us saying hey let's eval instead of teachers hinting there's something up. But I agree, the pattern of reporting behavior sounds like teachers making up their minds that this is the kid to watch. Very easy for teachers to fall into and so damaging for kids. Behaviorist class management systems can be, too.
