TI TestGuard™ 4.0 1

TI TestGuard™ 4.0

TI TestGuard™ 4.0 is an application for TI-83 Plus, TI-84 Plus and

TI-84 Plus C Silver Edition graphing calculators that allows educators

control of a student’s calculator in a testing environment.

Educators can use the TI TestGuard™ 4.0 application to:

• Delete selected data stored on students’ calculators before tests.

• Disable selected data on student’s calculator before tests, including

an option for all programs and selected applications.

Important! Be sure to follow the recommendations listed in the

section Before Using TI TestGuard™ 4.0.

• Restore previously disabled programs and applications on student

calculators after tests (if needed).

TI TestGuard™ 4.0 Requirements

The TI TestGuard™ application is not publicly available. To request

TI TestGuard™, call 1-800 TI-Cares.

Important! You must first install TI Connect™ on your computer before

you can install TI TestGuard™ 4.0 on your educator calculator. For

instructions on installing TI Connect™ go to education.ti.com/software.

Hardware Requirements

• TI-83 Plus, TI-84 Plus, and TI-84 Plus C Silver Edition calculators.

• TI USB Connectivity Cable for Windows®/Mac® – to transfer

TI TestGuard™ 4.0 from your computer to your calculator.

• I/O (Input/Output) unit-to-unit cable – to transfer the calculator

setup to a student’s calculator.

Note: TI TestGuard™ 4.0 does not run on the TI-84 Plus mode of the

TI-Nspire™ handheld software.

Software Requirements

• 1500 bytes of free RAM on your calculator.

• For TI-83 Plus calculators – OS version 1.19.

• For TI-84 Plus calculators – OS version 2.55MP.

• For TI-84 Plus C calculators- OS version 4.0.

2 Before Using TI TestGuard™ 4.0

Before Using TI TestGuard™ 4.0

Before you use TI TestGuard™ 4.0, consider the following

recommendations:

• Ensure that you are using the correct operating system on your

calculator. TI TestGuard™ 4.0 application functions with OS version

1.19 for TI-83 Plus, 2.55 MP for TI-84 Plus, and 4.0 for TI-84 Plus C

Silver Edition calculators.

• Advise students to install the latest operating system before an

exam.

• Advise students that TI TestGuard™ 4.0 deletes all programs and

applications on a TI-83 Plus calculator. Students must backup and

re-load programs and applications on the calculator using

TI Connect™ or by linking to another calculator.

•The

Disable logBASE and summation S( functions feature works

on a TI-84 Plus with OS version 2.55 MP and the TI-84 Plus C with OS

version 4.0.

–logBASE and summation S(functions are unavailable for TI-84

Plus with OS version 2.43 MP or earlier, and the TI-83 Plus. If you

create a calculator setup to disable these functions and then

transfer this setup to one of these calculators, TI TestGuard™ 4.0

ignores the DISABLE FUNC setting and no error is created.

– An attempt to disable logBASE and summation S(functions

for the TI-84 Plus with OS version 2.53MP displays an error

message. You must upgrade the OS to 2.55 MP and then transfer

the calculator setup.

• 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™ 4.0 displays a memory error. In that case, you must

manually remove RAM data from the student’s calculator before you

can run TI TestGuard™ 4.0.

• Ensure you are in possession of both your educator calculator and

the student’s calculator when transferring the calculator setup.

– Ensure the student’s calculator is on the Home screen.

Accessing TI TestGuard™ 4.0 3

– Ensure there are no active programs on a student’s calculator.

Note: A program is running if you see moving vertical lines or a

circle (TI-84 Plus C) in the top right corner of the calculator. Press

Éto stop any running programs. If an ERR: BREAK message

displays, select QUIT.

– Ensure that the student’s calculator is not in SEND/RECEIVE

mode.

Note: A calculator is in SEND/RECEIVE mode if the screen

displays Waiting...

– After you transfer a calculator setup to a student's calculator

and then re-enable programs, students may see programs with

random names when they press . Students cannot access

these programs, but can delete them by pressing yLMem

Management/Delete.

The SETUP CALCS screen offers the following configuration options:

DELETE Mode

Deletes data and applications on a student’s calculator:

Note:

• If you select APPS as the DELETE mode setting and also disable the

logBASE and/or summation S( function, TI TestGuard™ 4.0

changes the mode setting to ALL, so programs are also deleted.

Programs must be deleted to prevent the retention of the pre-

loaded programs containing functions or functionality not allowed

on exams. The following message displays:

ALL (Default) Clears Apps plus Vars in RAM/Archives, leaves

checked () Apps. Clears Pic and Image Vars (TI-84 Plus

C).

setup. You can have the student run language localizer again if

desired for the exam.

• A special situation exists between the Fundamental Topics in Science

(FunSci) and Science Tools (SciTools) apps. If you disable SciTools,

but do not disable FunSci, when FunSci calls SciTools, the SciTools

app launches and thus becomes re-enabled.
