There is a lot of information about schools that are valuable for a sub to know before they arrive at an assignment.  This desired information often includes:

• Parking directions
• Maps
• Check-in procedures
• Teacher dress code 

If you still feel like you need more information, you can contact the school using the information listed in the request. There is always a contact listed in each request, typically a school contact name with a phone number or an email address. (Ex: shown below)
