Where can i find studies to disprove the effectivness of 3 day weeks for kindergarten students?

That could be true that they are not developmentally ready for kindergarten. How old is your daughter? If she is not 4 already, it may be better for her to go to a daycare centre until she reaches that age. If she is, there will be an orientation day for all children who are registered for kindergarten to go to the school they will be attending to see what it looks like and gets to see what the other children do there. This is usually a half day morning session. The schools that are located in my area have the 3 day week sessions. It is usually Mondays Wednesdays and alternate Fridays and the other is Tuesdays Thursdays and then the Fridays when the other children are not there. One important thing you need to understand is why are they crying or going home? Is it that they were sent home because there was a safety issue with the other children in the room or because of something else that happened? Was it because they displayed behaviour that was acceptable at home but was deemed unacceptable at school? Getting the answers to these questions will I am hoping will change your outlook on your question. It seems to work very well here.

You might try contacting a local chapter of Headstart. (If you have one.)
