What can I do about my kindergartener?

Mom at a loss!! Idk what to do my oldest is in a kindergarden program to make sure shes ready. Well today was the first day and she ended up running out of the building and 4 teachers had to corner her and carry her back inside. They said if she has another day like yestersay it could withhold her. And i dont want that for her. She does deal with listening issues but this is so not cool. I talked to her she said she wanted me to stay i told her a way she could understand me and daddy already went to school and its her turn
