Visual Assistance Resources
Screen Magnifier Technology
Screen magnifier assistive technology enlarges the content displayed on a device’s screen to assist students with visual impairment. Although the TDS supports some non-embedded screen magnifier resources from third parties, CAI strongly recommends students use the zoom resources embedded in the TDS. These embedded resources were designed to magnify test content in the most intuitive and user-friendly manner for students. Embedded zoom resources can also be tracked when gathering data about students’ resource use. Refer to the Configuring Zoom Text Demonstration video for additional information.
The embedded zoom resources in the secure browser allow students to magnify test content to the following levels:
Table 1 provides a list of third-party screen magnifier tools that can be used in the TDS. The non-embedded screen magnifier tools listed in this table come with an increased risk of interoperability issues, require students to manually pan the magnification resource across the screen, and can include unwanted features that should not be used while testing. These non-embedded resources also cannot be tracked by the CAASPP or ELPAC programs when gathering data about students’ resource use.

Configuring ZoomText or Fusion to Recognize the Secure Browser
When displaying a test with a print-size accommodation at or above 3× magnification, the secure browser automatically enters streamlined mode. To retain the standard layout of a test but display it with a print magnification at or above 3×, consider using ZoomText or Fusion, which are magnification and screen-reading software that can be used with the secure browser. Use the following procedure to ensure ZoomText or Fusion recognizes the secure browser.
- If ZoomText or Fusion is running, close it.
- In Windows Explorer, go to the installation directory for the local version of ZoomText or Fusion. For example, with ZoomText version 10.1:
- Go to C:\Program Data\Freedom Scientific\ZoomText [version]\
- In a text editor, open the file ZoomTextConfig.xml.
- Search for a line containing the D2DPatch property, similar to the following:
<Property name="D2DPatch" value ="*,~dwm,~firefox,~thunderbird"/>
- On the same line, type ~CASecureBrowser12.0, immediately after ~firefox, (be sure to include the tilde and the comma).
- Save and close the file.
