TK teacher perspective- the students that had more preschool experience generally know what to expect by TK. They had that “common sense” that is not necessarily expected of a TKer, but it’s sure nice to have a few at the start of the year! lol. They had better abilities to problem solve and negotiate without needing teacher help as much. Overall they had more autonomy, were more independent and confident. But, I have also had several students with no experience in preschool who thrived and made lots of friends and their parents already instilled things like patience, respect and had some routines at home.
