Pearson recommends proctor caching for all online tests. A caching computer downloads and stores test data, such as multimedia files or test questions, and then serves that data to individual test computers from within the local network. This enables faster test page loading times and more efficient test taking.
- A proctor caching computer must be set up and running in your network, as described in Set Up and Use ProctorCache.
- You must know the IP address and port of that proctor caching computer. The default port is 4480.
Do Perform this BEFORE task before you create any test sessions. Later, while you are creating your test sessions, you will select the named configuration that you create here to be used for each test session.
From Setup > TestNav Configurations, open the task list and select Create / Edit TestNav Configurations and click Start.

Select Create Configurations. Enter the details of any proctor caching computers that you will use to precache tests. For more information about the Response File Backup Locations, see Configure Response File Backup Locations.

Click Test Connection to make sure the configuration works.
If the connection is not successful:
- Check that the proctor caching computer is set up properly and running on your network.
- Check that you have entered the correct IP address and port. The default port is 4480.
- Verify that the computer you are using to configure TestNav has Java installed and that the Java applet is allowed to run in your browser. (This feature requires the use of a Java applet. The computer from which you perform the action must have Java installed. You must allow the Java applet to run in your browser in order for you to test the configuration.)
If you only perform the configuration step, test content is not yet downloaded and precached. Precaching is not performed automatically, but something you must perform manually.
Do this AFTER Perform this task after you create all test sessions are created, but before the first test session beginshas been started. This will ensure that you cache all of the content needed. This feature requires the use of a Java applet, so the computer from which you perform the action must have Java installed and you must allow the Java applet to run in your browser in order for this to work.
From Testing > Sessions, search to find test session(s) set up to use proctor caching or click the down arrow next to the Search button to reveal and select the option to show all results. Select the session(s) you want to edit.

Click Precache. You can also click View Status at any time to view caching status. If content is not appearing when precaching and there are no students in the session, add students to the test session and try again.

An information screen will appear to let you know that caching is in progress and the parameters being used. At the same time, the ProctorCache application will open. From that application you can view caching progress. See Set Up and Use ProctorCache for directions.

The screen indicates that precaching has started.
The ProctorCache screen gives you access to information about cache status. See Set Up and Use ProctorCache for more details.
To refresh cached content, use the instructions in Manage Cached Content for Online Test Sessions.
