IHC is calling for investment and rapid changes in order to stop students with disabilities facing discrimination and consistent disadvantages in the education sector.
An Education Review Office report into schools' support for disabled learners, shows nearly half do not understand their legal obligations.
It says families need an independent complaints system.
The report says one in five disabled learners has been discouraged from enrolling in a local school and about half are not allowed to fully participate in school events like camps and field trips.
IHC's Inclusive Education Consultant Trish Grant spoke with Māni Dunlop.
