Technical Support FAQ

These are some Frequently Asked Questions about the technical aspects of the T.O.V.A.:


Should I choose the EAV or PTE setup?

See PTE vs. EAV for help choosing the best hardware setup for your computer.

Which computers are compatible with the PTE?

See our Compatibility page for information on specific computers.

Why doesn't the PTE work on my computer?

The Precision Test Environment (PTE) is a simplified operating system, like Windows or macOS. The PTE must be continually revised to work with new hardware (processors, displays, and storage), and new computers are released all the time. While the T.O.V.A. PTE is more compatible with new systems, there will always be some that we haven't fixed yet.

The EAV hardware setup is less portable, but it will work with any modern computer and monitor that meets our System Requirements. For more information, see our page comparing the two.

Which T.O.V.A. software version do I have?

The software version will show on the footer or header of a T.O.V.A. report or if you choose 'Help' from the main T.O.V.A. window. The current T.O.V.A. hardware is a black rounded box with a white T.O.V.A. logo on the top.

How do I know if I have the latest version of the T.O.V.A.?

If you have the T.O.V.A. 7, you do not have the latest version. To upgrade, purchase the Change Kit from our store.

If you have a T.O.V.A. 8 or 9 kit, go to our Downloads page and enter your serial number (from the sticker on the bottom of your black T.O.V.A. USB device). You can also check for updates in the T.O.V.A. software: In the main window of the T.O.V.A. application, click 'Status' > 'Updates'.

When is the next T.O.V.A. version going to come out?

We hope to release updates to the T.O.V.A. every few months. Beyond that, it is unwise to speculate.

How can I change the gender or age of the subject?

  1. Highlight the subject in the Subjects tab of the main window.
  2. Click 'Edit'.
  3. Correct the information there and click 'Save'.

Note that changing the subject gender or birthdate will modify which norms are used for the T.O.V.A. report and may invalidate the test. (The short-form test is only valid for ages 4 to 5.5; likewise, the long-form test is only valid for ages 5.5 and up). You should try to be sure that that the birthdate is correct before administering the test.

How can I back up my data?

All your T.O.V.A. subject and session information is now stored in a database, which makes it easier to search and sort for the information you seek. From the main window, you can click 'Help' > 'Back up database...'.

There are several automatic backup options detailed in the "Backing up the T.O.V.A. Database" section of our User's manual.

Which Java version do you use?

Our latest releases of the T.O.V.A. use Java 8 (8u171). The T.O.V.A. copies the Java we use locally, so that you no longer need Java "installed" to run the T.O.V.A.

See this page for a more detailed explanation.

How do I give a second test to the same subject?

Highlight the subject in the Subjects tab of the T.O.V.A. main window and click 'New session'.

How do I reassign a test session from the wrong subject?

You may find that a test was administered to the wrong subject. The T.O.V.A. provides a couple of ways to fix this problem.

NOTE: It’s important to avoid this mistake. Children below the age of five-and-a-half are not administered the same test format as older subjects. If you administer the wrong test format to your subject, the T.O.V.A. will not be able to properly interpret it.

  1. If the session should have been assigned to a subject that does not yet exist in the T.O.V.A. database, create the new subject first.
  2. Highlight the session in the Subjects or Sessions tabs of the main T.O.V.A. window.
  3. Click ‘Edit’ to bring up the ‘Edit Session Information’ window.
  4. Click ‘Assign to a different subject’ to bring up the ‘Reassign Session’ window.
  5. Select the subject the session should have been assigned to and click ‘Select subject’.
  6. When prompted, confirm that you want to reassign the session.

You can also reassign a session with drag-and-drop. Double-clicking a subject will expand it to show all the tests administered to that subject. You can then click on the test that’s misassigned and drag it to the correct subject.

Installing on a New Computer

If you're installing the T.O.V.A. on a new desktop, laptop, or All-in-One computer, first check out our System Requirements as well as our PTE Compatibility page.

Will the T.O.V.A. work on my computer?

Please see the latest T.O.V.A. System Requirements. If you are still not sure, please contact Technical Support, and we'll answer your questions as best we can.

Will the T.O.V.A. work on my network?

You may install the T.O.V.A. 8/9 on a networked computer system (almost every computer is on some kind of a network). However, your database must be stored locally on that system's hard drive. Storing data on a network shared drive, or sharing a database between systems, is NOT supported and may cause data loss.

Do I need admin access to my system to run the T.O.V.A.?

The T.O.V.A. needs to be installed by a user with administrator access to the local system, but afterward it can be run and even updated by any user on the system. Please note that modifying some T.O.V.A. settings will require an administrator.

Does the T.O.V.A. work with Windows 8 or 10?

Yes, the latest software (including the Precision Test Environment) works with most Windows 8 or 10 systems. Please review our System Requirements, see Compatibility for information on specific PC makes and models, and make sure to install the latest version here.

Will the T.O.V.A. work if I don't have a parallel port?

The new T.O.V.A. does not require a parallel port, only a USB port.

Will the T.O.V.A. work if I don't have a USB port?

Some of the newest computers don't have a USB-A port. Instead, they usually have a USB-C port. A USB C-to-A adapter (sold separately) should work fine for these systems.

Will the T.O.V.A. USB device work if I plug it into a USB hub?

The T.O.V.A. USB device must be plugged directly into your desktop or laptop's built-in USB ports. USB hubs cause communication with the device to be unreliable, and they should not be used, even if they work some of the time.

If I move my T.O.V.A. USB device, will the test results go with it?

No, your T.O.V.A. data is stored on your computer, not on the T.O.V.A. device.

When you finish the T.O.V.A. test, the test results are stored temporarily on the T.O.V.A. USB device (the black box). Then, when you spend a credit to save your test results, that session data is transferred to the T.O.V.A. database on the computer's local hard drive (by default, C:\ProgramData\TOVA\data). The test results are then removed from the device to make room for the next test session.

It's important to back up your T.O.V.A. data, and you have a number of options. See the T.O.V.A. User's manual for details.

How can I transfer my T.O.V.A. data to a different computer?

All your T.O.V.A. subject and session information is now stored in a database, which makes it easier to search and sort for the information you seek. See "Moving a T.O.V.A. Database" in the User's manual for details.

Can I install the T.O.V.A. on more than one computer?

Yes. You can install T.O.V.A. on as many computers as you need, but you can only administer tests when the T.O.V.A. hardware is attached. It is the T.O.V.A. hardware that keeps you within the software licensing agreement.

Does the T.O.V.A. require an internet connection?

No, the T.O.V.A. does not require that your computer be connected to the internet for testing or anything else, but it makes many operations quicker and easier.

T.O.V.A. Report

How do I print out the test report?

  • Highlight the session in the T.O.V.A. main window, choose 'View', and then click the printer icon.

If I view a test report a second time, will I use another test credit?

No. A test credit is used when the test's data is retrieved from the T.O.V.A. USB device and saved to the database. Once the test has been saved to the database, it can be viewed, printed, and exported as often as you like. If you import a T.O.V.A. 7 test, no credits will be spent unless the T.O.V.A. 7 data file was itself never interpreted. You will always be warned and asked to confirm before a test credit is used.

Please note that importing an uncredited T.O.V.A. 7 test does not modify the original data file. Therefore, if you import the test again, on another system, another test credit would be required. You can avoid this by exporting the test session from the T.O.V.A. 8/9 and importing that file on the other system. T.O.V.A. 8/9 files are always credited.

How do I compare the results of two or more tests?

  1. Highlight the two sessions in the T.O.V.A. main window.
  2. Click the 'Compare' button.

You can compare up to four sessions at a time. It is a very useful way to show patients or parents the main areas of attention measured graphically and over time.

Test Credits

Every time you save the results of a T.O.V.A. test results, you spend a T.O.V.A. test credit.

Where are test credits stored?

T.O.V.A. test credits and credit orders are stored on your T.O.V.A. USB device. This helps protect against computer crashes and viruses.

If I move my T.O.V.A. USB device, will the test credits go with it?

Yes. Since the test credits are tracked by the T.O.V.A. hardware, you may move the hardware and the credits will move with it. Your T.O.V.A. test data, however, will remain stored on the first computer's hard drive.

How many test credits do I have?

Click 'Credits' from the main T.O.V.A. window to see the number of credits currently available and to order more.

How do I order additional T.O.V.A. test credits?

See our Credit ordering FAQ.

Can I test subjects without having any test credits?

No. The T.O.V.A. 8/9 will not allow you to run tests or save test data unless you have test credits available. This is a change from the T.O.V.A. 7, but necessary because of essential differences in the hardware and software.
