We are currently going through the 'step into prep' program here in Melbourne. The primary school (state primary) we have chosen have been doing hour sessions every month since June.
The first time we all met together in the hall. The parents had chance to get to know each other & the kids got to play games together.
The second visit the group was split alphabetically one half went with one prep teacher the other half with the other. Parents could either leave & come back or stay in the staff room.
The visits since then have been the same but alternating between the teachers so the children can get to know both regardless of who they will have when the school year starts. They do different activities explaining & running the group as would be expected on a school day.
We have been really pleased with this transition as DS1 doesn't do well with change. Takes him a little while to get to know the teachers etc. swimming each term is horrendous as the teacher always changes lol. With going regularly he has got to know the school & had time to see what playtime is like. The music that is played calling end of play. Experience the environment.
Our kinder has played no role in the transition as DS1 will go to school associated with another kinder. The school that is associated with our kinder doesn't start there 'step into prep' program till November which will consist of an hour every fortnight. The state parents evening is at the end of November & then in Dec the half days the kids do. I much prefer the slow introduction as it becomes part of everyday chatter. You have chance to speak with the teachers, see the school environment on a normal 'working day', observe the kids/staff interaction on many different occasions. It also helps if you do decide that the school you initially chose isn't right you have time to change. You can even do 'step into prep' at two different schools if you can't decide.
We were given information initially in the things it would be good for DS to know or be able to do himself. Information on the school, after or before school care etc.

Hope this helps with your assignments.
