In one of the local primary schools, they host a marketplace a few times of the year so local craftspeople can sell their wares and funds can be raised for the school. Each time they open the market 30-60 minutes early just for children with autism so they can explore the market in a much quieter and calmer environment. The organisers didn’t have to do this, but decided to be more inclusive.
In other schools and universities students with dyslexia are given a small amount of extra time to complete the tests and exams so they read questions more.
Little changes, especially those which are choices, are noticed. They may be small, but when regularly applied it shapes the culture drip by drip by drip.
