Supported Operating Systems for Student Testing

This section describes the supported operating systems for computer-based testing that use the secure browser or a web browser. The secure browser provides a secure, online testing environment in which a device is restricted from accessing prohibited computer applications (local or internet-based) or copying or sharing test data. The purposes of this environment are to maintain test security and provide a stable testing experience for students across multiple platforms.

For optimal performance, all systems should have the latest minor updates and patches installed. Major updates, including new versions, require review and testing prior to use in CAASPP and ELPAC computer-based testing.

Desktops and Laptops

Table 1 lists the operating systems and devices required for student testing in 2021–22. Computer-based testing functions effectively with the minimum requirements listed. However, the recommended specifications provide improved performance.
