My son started going to Point Grey stəywəte:n̓ Secondary School, but I didn't know how to pronounce it so I asked the school here but never got a response.
Then I decided to ask on Quora, which did lead to an approximate pronunciation of it as well as some information about which Canadian First Nation's word it is.
Still, I feel like the placement of that word in the title without an explanation of it causes confusion. I think it was probably done in the spirit of respect, however by putting it there without providing more information, I think it creates more confusion and therefore doesn't bring about the desired outcome. I hope the school will reevaluate how it brands itself, and provides more details on what it is doing to be respectful to indigenous cultures than just creating confusion and mystique around them.
On a related note, I had difficulty hunting for my tweet with : https://twitter.com/search?q=stəywəte:n̓ I believe it is the colon in the tweets which throws the search index off. Perhaps they might use the IPA long vowel character ː to write stəywəteːn̓, so search indexes would realize it's human language and not punctuation.
