Solution 10564: Information about the TI TestGuard™ App.

What is the TI TestGuard App?

The TI TestGuard™ application is a tool that teachers can use to gain more control over their testing environments. TI TestGuard clears programs, lists, applications, and other stored data from students’ calculators. However, teachers have the option to leave specific applications on students’ calculators. In addition, TI TestGuard uses a password feature to confirm that the calculators have been cleared.

There are two versions of the TI Test Guard app, TI TestGuard 1.0 and TI TestGuard 4.3. Texas Instruments recommends TI-83 and TI-89 family users install the TI TestGuard 1.0 app while TI-83 Plus family (which include the TI-83 Plus Silver Edition) and TI-84 Plus family (which include the TI-84 Plus Silver Edition and TI-84 Plus C Silver Edition) users install the TI Test Guard 4.3 app.
