The following link will take you to a page on the Education Authority website designed to support pupils with transition to secondary school.
The materials produced by Autism Advisory & Intervention Service (AAIS) are primarily aimed at ASD pupils however like so many Special Educational Needs resources it is essential for some and good for all.
At the bottom of the page there is a video called Moving on Up and also a link to a Moving on Up Transition Support pack for parents to use with pupils at home.
