This exchange is run by the school PTA as a Facebook page and you may have to request to join. Check the info on the page. Get in touch if you need uniform or have some uniform from that school to donate.
If you get in touch but they can’t help you, try LS16 Community Uniform Exchange or Uniform 4 All North West Leeds Facebook groups as they may cover this school. Their details are listed on the Facebook Pages section. Alternatively you could try one of the Community Exchanges as they hold generic uniform stock. You could also try our FB group.
