Answers:

  1. What do I need to do to set up my school labs to participate in the computerized ISAT?
    • There are two ways to configure your computer labs to participate in the ISAT test:
      • Case 1, figure 1: ISAT CAL testing on-line. This is the easiest way to configure your lab to be ready for the ISAT testing. In this case all you need to do is install the CAL test delivery software in each of the computers to be used for ISAT testing. The rest of the FAQs will give you more information on the system requirements and how to configure the software to work properly.
      • Case 2, figure 2: ISAT CAL testing with Local Caching Server (LCS). In this scenario you will need to install the CAL test delivery engine in each computer to be used for ISAT testing (as indicated in case 1), and you will also need to install the LCS software in one of your school computers. In this scenario, each CAL end client will need to be configured to work with the LCS. See section on the Local Caching Server below to learn how to configure your lab to use the LCS.

  3. How do I know if I need to install the LCS?
    • For many schools, the simple set up without the LCS works fine. But for some schools that have limited bandwidth and need to test large number of students simultaneously, the LCS might be a good idea. For instance, our experience shows that a school with a T1 connection should be able to test up to 150 students simultaneously without a LCS.
    • If you are not sure if you need to install the LCS, you can set up your lab without the LCS and if your students experience some long delays while loading their tests, you can then install the LCS and configure the end clients to work with the LCS.

  5. What are the system requirements to install the CAL software?

  7. How do I install the CAL software on my computers?

  9. Do I need administrative privileges on my computers to install the CAL software?
    • Yes, to install the CAL software on computers that support multiple users, you need to login to your computers as a user that has privileges to install new software.
    • back to top

  11. Where is the default location of the installed CAL software application?
    • For Windows the default location of the installation is C:\ProgramFiles\ISAT\. For Macs the default location of the installation is the folder \Applications\ISAT\.
    • back to top

  13. Where is the default location of the shortcuts for the application?
    • For Windows the default location of shortcuts is Start->Programs->ISAT. Another shortcut is also placed on the desktop. For MAC users a shortcut to the application is placed on the desktop. A shortcut will also be placed in the folder \Applications\ISAT\.
    • back to top

  15. Once installed, how do I run the CAL software?
    • In Windows, click the ISAT shortcut on your desktop or use the ISAT shortcut on Start->Programs->ISAT on the start menu. On MAC systems, click on the ISAT shortcut on the desktop or in the folder \Applications\ISAT. Note that technical staff may decide to create shortcuts in different locations, in which case you need to instruct your students where to find the shortcuts in order to launch the CAL application.

  17. What is the Preference program?
    • The Preferences program is an application included in the installation of the CAL software. This program can be used by technical staff in your school to configure features such as the Speech Feature, Local Caching Server, automatic updates, proxy servers, the use of SSL, and troubleshooting problems with installation and testing.
    • back to top

  19. Where do I find, and how do I run the Preferences program?
    • On Windows systems, go to Start->Programs->ISAT-> Preferences. On MAC systems, go to the Preferences program located in the folder \Applications\ISAT.
    • back to top

  21. How do I set up my computers for an audio accommodation?
    • To use this feature, an audio accommodation must be available for the test the student is enrolled to take and the student must be marked for an audio accommodation in the Student Editor via the Management Tools. The audio accommodation is only available for Mathematics and Science and is designed to work only with the Cepstral David voice.
    • To set up a computer for an audio accommodation, the following needs to be done:
      1. Make sure a sound card is present on the computer.
      2. Download the Cepstral David voice by clicking on "Cepstral David" located in the Download Center of the Management Tools.
      3. Run the installer only on the computers identified to be used for an audio accommodation and follow the instructions to complete the installation.
      4. Enable the Speech Feature by following these steps:
        • Open the "Preferences" program from: Start/Programs/ISAT/Preferences.
        • Select the "Speech Feature" tab.
        • Check the “Enable Speech Feature” check box.
        • Click “Apply”.
    • If you are using a Windows 98 system, you also need to download and install the Microsoft SAPI 5.1 Redistributable, in case you don't have it already installed.
    • back to top

  22. Does CAL support Proxy servers and proxy server authentication?
    • Yes, the use of proxy servers and proxy server authentication is supported by the CAL software. CAL tries to automatically detect and use the proxy setting configured in your computer. In Windows systems, the proxy settings are retrieved from the Windows registry: HKEY.CURRENT_USER\\Software \Microsoft\\Windows\\CurrentVersion\\Internet Settings\\ProxyEnable and ProxyServer. If these values are not set, you will need to manually set the proxy setting using the "Preferences" program. In Mac OSX systems, the proxy settings are retrieved from the Network manager. In most cases you will not need to worry about proxy settings, but if you need to manually edit them, follow these steps:
      1. Locate and open the Preferences program.
      2. In the Proxy Tab check "HTTP Proxy" box and fill in the http proxy host and proxy port (contact your system administrators to obtain this information).
      3. If you use a different proxy server for SSL communication, select the "Secure Proxy (HTTPS)" box and fill in the corresponding proxy host and proxy port (contact your system administrators to obtain this information).
      4. Click Apply or OK.

  24. What are the "Troubleshoot" and "Log File" panels in the Preferences Program?
    • The Troubleshoot panel helps you find problems with the CAL software. There are four different tests that are run to verify if your system is ready for CAL testing. The following are the tests available and possible actions to take in the event of test failure:
      1. Writing to Local File System: The CAL application writes log messages to a file in the local file system: user_home\.isat\cal-isat.log, (for Windows this is C:\Documents and Settings\user\.isat\cal-isat.log). This test confirms whether there are sufficient permissions for writing to this file. The failure of this test is not critical since CAL will still run, but messages will not be logged into the log file.
      2. DNS Tests:
        • Domain Name Lookup: This tests if there are any problems with CAL software locating your DNS server.
        • CAL Domain Name Lookup: This tests if your computer can reach the CAL central data servers by their domain name.
        • The passing of the above tests is critical for the correct operation of the CAL application. A failure indicates that there is a problem with the DNS servers at the schools and/or at the CAL servers. If you determine that this situation is not a local DNS problem, please contact us.
      4. Connectivity Tests:
        • General Internet Connectivity: This tests if the schools are able to connect to the Internet, which is essential for connecting to the CAL central servers.
        • CAL Internet Connectivity: This tests if your computer is able to connect to CAL servers.
        • The passing of the above tests is critical for the CAL application to operate properly.
    • Log File Panel
      • The Log Panel displays the contents of the CAL log file (user_home\.isat\cal-isat.log). This file can be useful when troubleshooting the application. The panel displays the last 500 lines of the log file at a maximum.

  26. Does CAL support secure Internet communication?
    • Yes, CAL supports secure SSL communication. To set up computers to use SSL communication, follow these steps:
      1. Run the Preferences program.
      2. Select the Secure Connection tab.
      3. Check the Enable Secure Connection check box.
      4. Click Apply or OK.
      5. Also make sure that your school network allows outgoing SSL communication on Port 443, and that your proxy server (if used) supports SSL communication.
    • back to top

  28. What port needs to be open for the CAL software to work properly?
    • You need to allow outgoing communication on port 80, and if you set up CAL to use SSL communication you will also need to allow outgoing communication on port 443.

  30. Why does the new update of the CAL software fail after being deployed when the CAL application is opened?
    • You see this problem if the current user of the computer does not have privileges to update the software.
    • back to top

  32. How can I get the updates of the CAL software?
    • CAL has an automatic update feature that checks for updates every time CAL is launched. If an update is available, it will be automatically downloaded and deployed onto your computers. However; if your computers support multiple users (Windows NT, 2000, 2003, XP, MAC OS X), in order for the updates to be successfully deployed, the systems must be logged in by user with privileges to write to the folder where the CAL software was installed. The default installation of CAL sets permissions so that any user of the computer could automatically download and deploy available updates by simply running the CAL application.
    • It is important to note that these default permission settings will also grant permissions to any user to delete or modify the CAL application. If you decide that this is not a good decision in your environment, you can manually restrict the permissions of the CAL installation folder. In order to get CAL updates when they become available, you will need to have a user with administrative privileges run the CAL application. There could also be systems or situations in which the default permission settings fail and users without administrative privileges will not be able to get the available updates. In this case you have three options:
      1. Manually change permissions to the CAL installation folder so that all users have permissions to download and deploy the available updates.
      2. When updates are available, have a user with administrative privileges launch the CAL application so updates are automatically deployed.
      3. Windows users can use Window Installer-based patches to automatically deploy updates using Software Installation and Active Directory Group Policy. See question 18.

  34. How do I use Windows Installer-based patches to deploy CAL updates using Software Installation and Active Directory Group Policy?
    • You have the option of using patches for Windows Installer technology to deploy the CAL updates. When new updates are made available, a Windows Installer Patch for the update will also be made available at the Download Center. You will need to download and run the patch in your computer for the update to be deployed. Refer to the following link to learn more about Windows Installer.

  36. What should I do if error messages display while students are testing?
    • "Unable to connect to the central server. Please check your Internet connection. Contact your teacher or test administrator."
      "Your internet connection has been lost. Contact your teacher or test administrator to reactivate your password for this part of the test."
      "A system error has occurred. Contact your teacher or test administrator."
      "A system error has occurred. Contact your teacher or test administrator to reactivate your password for this part of the test."
    • Check if you have a proper Internet connection in the computers with the problem. If your connection is good, open your browser and go to http://isat3.caltesting.org/test.jsp to test the communication to the CAL data center. If you get a "Success!" message, then try to run CAL again and take a Practice Test. If you still get the same results, open the CAL Preferences program to check if the CAL proxy settings are set correctly. You can also use the Troubleshoot tab in the Preferences program to assist you with troubleshooting the problem.

  38. What are the url(s) for the servers that ISAT connects to?
    • These are the URLs that the CAL software needs to connect to:
      • http://isat.caltesting.org
      • https://isat.caltesting.org
      • http://isat3.caltesting.org
      • https://isat3.caltesting.org
      • http://updates.altec.org

  40. What should I do if I get a blank screen on a Mac 10.4?
    • In very few situations we have experienced problems with Mac 10.4 systems randomly getting a blank screen when CAL is launched. We continue to work on a fix to this problem, but the current solution is to close the CAL application by using the X in the top corner and hitting the Enter or Return key. Then, reopen the CAL application again. This should clear the problem.
