Ashley Rose recently posted a very nice Google Slides Presentation on Scheduling Team Secrets in the High School Counselor Resources Group on Facebook. The presentation includes information on the pre-scheduling phase as well as the 8 scheduling phases.
Here is a link to the entire slide presentation: Scheduling Slide Presentation
She also includes a link to a Google Doc (template) that can be used to have discussions with your department around any sorts of requests that the master scheduling team would need to know about; items like room sharing, collaborative planning groupings, strategic course placement, etc. When filling out, please do so in a group discussion format. Where possible, please link your request to either a District Stretegic Plan item, or one of our SIT Goals. As always, reach out if there are questions. Here is the link to that doc: Scheduling Doc
