Cambium Test Technology Setup, Device Readiness, and ProctorCache — Questions and Answers
Question 1: What is the primary function of the Cambium ProctorCache tool?
- To pre-download test content to a local server so students can test with reduced internet bandwidth requirements (Correct answer)
- To encrypt proctor login credentials before they are sent to the Cambium servers
- To monitor student screens in real time from a proctor workstation
- To automatically submit student responses when a testing session ends
Correct answer: To pre-download test content to a local server so students can test with reduced internet bandwidth requirements
ProctorCache is a caching application installed on a local school server. It downloads test content (items, images, audio) in advance so that during the test, students pull assets from the local cache rather than over the internet, reducing bandwidth demands and improving performance in low-connectivity environments.
Question 2: Before a testing window opens, a technology coordinator should run the Cambium Infrastructure Trial to verify which of the following?
- That student devices can successfully connect to the testing platform and load content under real test conditions (Correct answer)
- That student scores from the previous year are correctly imported into the reporting system
- That teacher accounts in TIDE have the correct subject permissions
- That the Cambium scoring rubrics are aligned to current state standards
Correct answer: That student devices can successfully connect to the testing platform and load content under real test conditions
The Infrastructure Trial is a pre-operational readiness check that simulates a real test session, verifying device connectivity, secure browser function, content loading, and network throughput — surfacing issues before live student testing begins.
Question 3: Which browser environment is required for students to take a Cambium-administered summative assessment?
- The Secure Browser provided by Cambium, which blocks access to other applications and websites (Correct answer)
- Any current version of Google Chrome with ad-blocking extensions disabled
- Mozilla Firefox with JavaScript enabled
- Microsoft Edge in InPrivate mode
Correct answer: The Secure Browser provided by Cambium, which blocks access to other applications and websites
Summative assessments administered through Cambium's platform require the Cambium Secure Browser (also called the Student Testing Application on some platforms). It locks down the testing environment by preventing access to external applications, the clipboard, and other browser tabs — supporting test security requirements.
Question 4: A proctor reports that several students are seeing a 'Session Not Found' error when they enter the session ID. What is the most likely cause?
- The proctor has not yet approved the students' login requests in the Test Administrator Interface (Correct answer)
- The students' TIDE records contain incorrect grade-level information
- The ProctorCache server has not been updated with the latest content
- The secure browser version on the student devices is out of date
Correct answer: The proctor has not yet approved the students' login requests in the Test Administrator Interface
In Cambium's test delivery workflow, a student enters their credentials and the session ID, but they enter a waiting room and cannot begin until the test administrator explicitly approves them in the Test Administrator Interface (TAI). If the proctor hasn't taken that step, the session appears invalid to the student.
Question 5: How far in advance of the testing window should a school ideally complete the Technology Readiness Checklist?
- Several weeks before testing, allowing time to resolve any device or network issues identified (Correct answer)
- The day before testing begins, to ensure all settings reflect the current state
- During the first testing session, while students are logging in
- After testing ends, to document the configuration for next year's reference
Correct answer: Several weeks before testing, allowing time to resolve any device or network issues identified
Cambium recommends completing readiness checks well in advance — typically 4–6 weeks — so that any issues with device compatibility, bandwidth, secure browser installation, or ProctorCache setup can be remediated before students are affected.
Question 6: What does it mean when a student device fails the 'Screen Resolution' check in the Cambium Secure Browser diagnostics?
- The device's screen is too small or set to a resolution below the minimum required, which may prevent the test from displaying correctly (Correct answer)
- The student's TIDE record does not include a reading accommodation for enlarged text
- The ProctorCache has not pre-downloaded the test's image assets
- The device's operating system is incompatible with the current Cambium test delivery engine
Correct answer: The device's screen is too small or set to a resolution below the minimum required, which may prevent the test from displaying correctly
Cambium specifies a minimum screen resolution for test delivery (commonly 1024×768 or higher). A failed resolution check means the device cannot render test content as designed — items may be cut off or navigation controls obscured — and the device should not be used for testing.
