The objective of the vendor index table is to easily determine the location of a vendor in the directory.
How to use the table:
- Identify and locate the desired vendor using the “Search” entry box or the “Vendor” dropdown box.
- Once the list appears, identify the Grade(s) where the vendor is used.
- Go to the main navigation menu bar and place your cursor over the menu “Teachers Resources.”
- A dropdown menu appears.
- Move the cursor over the desired grade classification and a sub-menu appears showing the individual grades (the exception is High School and Instructional Technology).
- Click on the Grade Resource and you will be transferred to the appropriate resource page.
- Identify the category and sub-category.
- Click on the sub-category and the available vendors are listed.
