Allowlisting URLs for Online Testing

Testing sites provide test items as well as support services such as dictionaries and thesauruses. Ensure that the school’s network allows for the following:

• If the school’s filtering system has both internal and external filtering, the URLs for the testing websites must be allowlisted in both filters. Ensure the filtering system is not configured to perform packet inspection on traffic to CAI servers. Refer to the filtering system’s documentation for specific instructions.
• Be sure to allowlist URLs in any multilayer filtering system (such as local and global layers).
• Ensure all items that handle traffic to *cambiumtds.com and *.tds.cambiumast.com have the entire certificate chain and are using the latest TLS 1.2 protocol.

URLs for Testing Websites

This subsection lists the domain names for CAASPP and ELPAC online testing and nontesting applications. Ensure the testing devices have access to a DNS server that can resolve those names.

Test Administrator, Test Examiner, and Student Testing Websites

Testing servers and satellites may be added or modified during the school year to ensure an optimal testing experience. As a result, a user is strongly encouraged to allowlist at the root level using a wildcard. Wildcards are encouraged, as servers may be added or removed from the field without notice.

CAI URLs for testing websites—test administrator, test examiner, and student testing websites, as well as for the assessment viewing application—are as follows:

*cambiumast.com

*cambiumtds.com

*cdn.cambiumtds.com

*cdn2.cambiumtds.com

*resources.cambiumtds.com

*static.cambiumtds.com

*tds.cambiumtds.com

Online Dictionary and Thesaurus

Some online assessments contain an embedded dictionary and thesaurus provided by Merriam-Webster. The following Merriam-Webster URLs should also be allowlisted to ensure that students can use them during testing:

• media.merriam-webster.com
• www.dictionaryapi.com

URLs for Nontesting Websites

Table 1 lists URLs for nontesting sites, such as TOMS, TIDE, and CERS. LEAs are encouraged to add these URLs to local allowlists.
