Appendix A: Operating System Support Plan for the 2023–24 Test Delivery System
A supported operating system is one for which CAI provides updates to the secure browser for that operating system. CAI provides such updates as the supported operating systems are updated or as bugs in the secure browser are detected and fixed.
The support plan describes CAI’s plan for supporting operating systems during the upcoming test administration and following years. This plan helps LEAs and schools manage operating system deployments based on the support timelines. Table 1 through table 5 present the supported operating systems tables.
Timing of Secure Browser Updates
CAI will support major and minor version upgrades for Windows, macOS, Linux, iPadOS, and ChromeOS upon the completion of internal testing following their release. CAI may provide secure browser updates for new major and minor version upgrades of Windows, macOS, Linux, iPadOS, and ChromeOS, if necessary.
A “major version upgrade” of an operating system is usually denoted by an increase in the version designation’s whole number. For example, the upgrade from Windows 10 to Windows 11 was a major version upgrade.
A “minor version upgrade” is usually denoted by an increase in a number after a decimal point. For example, the upgrade from macOS 13.3 to 13.3.1 was a minor version upgrade. For minor version upgrades to iPadOS and ChromeOS operating systems, CAI will provide mobile secure browser updates to ensure compatibility.
