NIST is a managed, inclusive school, and we have an extensive support services team on campus. What the support looks like very much depends on the student's specific needs and, in some cases, the tools they are already used to using. Our learning support specialists provide a variety of individual and group support, including push-in (classroom) and pull-out models that focus on a strength-based approach. There is more information available here on the NIST website. We maintain an extensive support department that provides support across a range of areas, including English as an additional language, speech language therapy, educational psychology, occupational therapy, behavioural coaching and enrichment support.
