Site Preparation is most effective when it is implemented at the district level, then carried out at the site level. It is important for school districts to acknowledge the importance of creating SubFriendly sites and develop a general plan of action at the district level to be used as a foundation at the Site Level. Buy in at the district level, as well as support (in action and through budgeting), enables sites to more efficiently develop site-level plans of action. District level direction can also provide consistency across the district. For example, the use of a common color class SubFolder.
