Teacher Machines
According to The TN Cambium Portal, Test Administrators (TA) need a computer running, “Nearly any modern device, including mobile devices like tablets and phones, with any modern browser can be used to access the TA Interface and administer a testing session. The TA Interface is a website. Any device you already use to check your email, browse Facebook, read news articles, or watch YouTube should be capable of administering tests.”
Access to other CAI systems requires the use of one of the following supported web browsers:
-
Chrome 138 or higher
-
Firefox 138 or higher
-
Edge 138 or higher
-
Safari 17 or higher
Your teacher leased laptops have macOS, with Chrome, Firefox, and Safari installed. If you think you need Edge, it’s in Self Service under the Connecting (Web Browsers, Messaging, etc.) section.
Student Machines
Student machines' requirements are listed here. At the bottom of that page includes hardware allowed. If you use external mice or keyboards with your Chromebooks, some are NOT allowed!
Please note, student Chromebook devices without a USB charger have experienced AUP and cannot run the minimum required version of ChromeOS for this test. If it doesn't have a USB-C charger, it cannot be fixed/repaired to work with this test.
A USB-C type charger looks like this:

Vocabulary Terms
While most of this is understandable by educators, the public may be confused by the amount of acronyms. Here are some definitions.
- ELL: English Language Learners
- ELPA21: ELPA stands for English Language Proficiency Assessment. The 21 stands for the Twenty-First century. The assessment was created to assist English learners and their instructors. The ELPA 21 website offers more information.
- Self Service: we use Jamf’s Self Service to distribute software. An icon in the teacher’s Dock of their Mac looks like the PCSS torch. Teachers can access new programs, information, and configure printers with the click of a button.
- TIDE: Test Information Distribution Engine. TIDE is a property of Cambium Assessment, Inc.
