I have no advice for you except to not let your own fear or concern show. Just be excited and happy, and she'll feel more excited and happy since little ones so often take their cues from us. But yeah----I'm very happy that our school has opportunities to see the school and stuff. I think it will help to cut down on the anxiety for all involved. I personally had NO problem in kindergarten (I didn't turn 5 until mid-October; the rules were different then though) because I was excited to go to school, and we didn't have all the introductory stuff. Mom says we lived so far out in the country a highschool bus picked me up and dropped me off. She wanted to stand at the end of the drive with me and I patted her arm and said "No mom, I a big girl now". She sat on the porch and cried, she said. My brother, same way: no special orientations, he just met everyone on the first day. We survived and it's going to be ok for your daughter too. Kindergarten teachers are a special breed, in my opinion, and they know how to handle little ones and understand how to make them happy and comfortable.
But yeah, things are much different now for my son. Last May, the last week or two before school let out, we went to early registration and had an appointment for my son to meet the counselor and have some basic "testing" done. They made it sound like no big deal, but it was just a couple counselors and my son, I wasn't invited in with my 2 year old in tow.....20 minutes later they came back and that was it. They were very excited that he not only knew sight words but was also sounding out words that were unfamiliar to him, etc....when we were in the car I asked what happened and he told me they played puzzles, shapes, and games, counted, read, talked a bit, etc. I'm guessing it was a placement test of some sort.
Then at the beginning of June we had kindergarten orientation where we went to a random kindergarten class and some current kindergartners (leaving for 1st grade) were there to partner up and show the new incoming students around the class, did different activities with them, there was a little presentation for the kids to watch (put on by other kids), and then they sang songs, played a game, and colored. While they were doing that, the parents got to see the computer lab, robotics department, and go to the lunchroom to hear the guidance counselor, assistant principal, and head principal give talks and explain some things. End of June, we had a school "family picnic" catered by a local restaurant where we got to see the set up of the school, walk to his assigned K class, most got to meet their teachers then (we didn't because the current teacher was moving to a different grade and they hadn't hired my son's teacher yet), but at least we got to see the room and know where it is, where the bathroom is, etc. Next Friday we have a meet the teacher scheduled, where we will go to his class, meet his new teacher, bring in the supplies, meet his teacher, etc. It's not private, it's just from 1-3 and everyone just comes as they can. The following Monday is his first day of school. It may be excessive to some, but I appreciate it! It has helped build up excitement and anticipation, not anxiety, over the summer.
A friend of mine says her son is moving to intermediate school (grades 5-6) this year and they're having a 3 hour camp for several days this week (9 hours total), to get them ready. I guess it cuts down on the actual school time being spent on telling them what is expected of them or whatever. He's liking it.
