5 Introduction In the past, students have been responsible for resetting their own calculators before a test or an exam to ensure an equal baseline for all participants. However, students have learned ways to bypass reset and disable options and keep formulas, calculations, and data on their calculators. TI TestGuard 3.0 is an application (app) for TI-83 Plus and TI-84 Plus graphing calculators that allows you more control over a student s calculator in a testing environment, and ensures fairness for all students. First, you install TI TestGuard 3.0 on your educator calculator using TI Connect or another TI-83 Plus or TI-84 Plus calculator. Then, you use TI TestGuard 3.0 to create the calculator setup that students will use for an examination. During this setup, you can choose to delete or disable certain data; delete or disable programs; or delete, disable, or keep certain applications. Once you have created the calculator setup, you can double check it by viewing a summary, and then transfer this setup to a student s calculator using a (non USB) input/output calculator-to-calculator cable. When the transfer is complete, TI TestGuard 3.0 displays a unique and randomly generated confirmation code on both your educator calculator and the student s calculator. The confirmation code is the same on both calculators. After an exam or test is over, you can use TI TestGuard to re-enable those programs and applications you previously disabled on a student s calculator. A student can also re-enable a programs and applications by linking to another TI-83 Plus or TI-84 Plus calculator and receiving any file. Audience This Guidebook is for teachers, instructors, or educators who use TI TestGuard 3.0 to create student calculator setups for examinations for TI-83 Plus and TI-84 Plus calculators. What s New? TI TestGuard 3.0 contains two new features: Disable logbase and summation S( functions - This feature allows you to disable the logbase and summation S( functions on a student s calculator.

8 Before Using TI TestGuard 3.0 Before you use TI TestGuard 3.0 to create a calculator setup and transfer this setup to a student s calculator, consider the following classroom management recommendations: Ensure that you are using the correct operating system on your calculator. For TI-83 Plus calculators, TI TestGuard 3.0 functions with OS version 1.19; for TI-84 Plus calculators, TI TestGuard 3.0 functions with OS version 2.55MP. Coordinate your examination requirements with other educators to avoid deleting any data or applications on a student s calculator that the student may require after your exam for other examinations or classes. Advise students to install the latest operating system on their calculators before the exam. Create a list of programs and applications you allow for your examination, and communicate this to students and other educators. Create a list of programs and applications that you do not allow for your exam, and advise students to back up these programs and applications prior to the exam. Advise students that TI TestGuard 3.0 deletes all programs and applications on TI-83 Plus calculators, and cannot disable programs and applications on these calculators. Advise students that if they are using a TI-83 Plus calculator, and you run TI TestGuard 3.0, they must re-load programs and applications on their calculator using TI Connect or by linking to another calculator. Ensure that the student handheld has 2500 bytes of free RAM. Note: If the student s calculator does not have enough free RAM, TI TestGuard 3.0 displays a memory error. In that case, you must manually remove data from RAM before you can run TI TestGuard 3.0. Ensure the student s calculator is on the Home screen. Ensure there are no active programs on a student s calculator. Note: A program is running if you see moving vertical lines in the top right corner of the calculator. Press to stop any running programs. If an ERR: BREAK message displays, select 5. Ensure that the student s calculator is not in SEND/RECEIVE mode. 4 Before Using TI TestGuard 3.0

36 Archive Full This error occurs when the TI-83 Plus or TI-84 Plus does not have sufficient memory for the application. To create enough space for an application, you must delete an application and/or archived variables from the calculator. Before deleting an application from the TI-83 Plus or TI-84 Plus, you can back it up to a computer by using TI Connect. Once saved, you can reload it to the calculator later using TI Connect. Communication Error This error indicates the Flash installer is unable to communicate with the TI-83 Plus or TI-84 Plus.

If this does not correct the problem, try a different cable and reboot your computer. If you continue to get this error, please contact education.ti.com/support for assistance. Validation Error This error occurs if electrical interference caused a link to fail when you loaded an application onto your calculator. Try to install the application again. If you continue to receive this error, contact education.ti.com/support. Note: This error is not associated with the Validation OS check in the TI TestGuard 3.0 application.
