Final answer:
A Stamp Form is not included when sending a school order for educational materials, which normally contains the school's Purchase Order, Digital Order Form, and possibly Multisite Form and Scholastic Digital Manager Codes, if applicable.
Step-by-step explanation:
When sending an order that includes educational materials, certain documents are typically expected. For example, a Purchase Order (P.O.) is usually required by a school to authorize the transaction. Additionally, a Digital Order Form may be included to specify the digital products being purchased. A Multisite Form could be needed if the order is for multiple locations. Scholastic Digital Manager Codes might be included if the purchase involves access to digital resources provided by Scholastic. However, a Stamp Form would not ordinarily be part of such an order. Stamp Forms are typically used for collecting stamps or for requests related to stamp-related transactions, which would not be relevant in this context.
