Topics
2
By the end of this presentation, you should be able to: Understand your role and responsibilities Prepare for online tests at your school Install the secure browser Troubleshoot technical problems during the tests.
Objectives
3
• Logins and passwords• Minimum system requirements• Secure browser• Determining system readiness/network
capacity• Troubleshooting technical issues
Technology Coordinator Tasks
4
Network Connection:• A stable, high-speed (wired or wireless) network and
internet connection are required for the test. • The response time for each test depends on your
network’s bandwidth, number of students simultaneously testing, size of test content, proxy server (if used), and other factors.
Network Requirements
5
Network Configuration:• Session timeouts on proxy servers and other devices should be set to
values greater than the average scheduled testing time. For example, if test sessions are scheduled for 60 minutes, consider session timeouts of 65–70 minutes.
• Web proxy servers must be configured to NOT cache data received from servers.
• For any device that performs traffic shaping, packet prioritization, or quality of service, the IP addresses to be used for testing should be given a high priority to ensure the best performance.
Network Requirements
6
Whitelisting:
Content filters, firewalls, and proxy servers should be configured to allow the URLs for the servers being used.
The URLs for the following sites need to be accessible for testing:• Secure Browser • Test Administrator Training Sites• Practice and Training Test Sites• Test Administrator Interface• Test Information Distribution Engine (TIDE)• Interim Teacher Hand Scoring System (THSS)• Online Reporting System (ORS)
Network Requirements
7
Performance Factors:• Bandwidth• Number of students simultaneously testing• Wireless networking configuration (if used)• Secure browser
Network Requirements
8
Bandwidth:• At least 20Kbps bandwidth per student being tested• Affected by both Local Area Network (LAN) traffic and
internet traffic from the router• LAN should always be analyzed to determine potential
traffic bottlenecks
Network Performance
9
Number of students simultaneously testing:• Network performance may slow when large numbers of
students are testing at one time. • Multiply the number of students being tested by 20Kbps to
get an estimate of bandwidth needed, and compare that estimate with the network speed test.
• Perform network analyses at different times to ensure adequate capacity.
Network Diagnostics Tool
10
Wireless Network Configuration:Wireless traffic must use encryption.• Wi-Fi Protected Access II (WPA2) • Advanced Encryption Standard (AES)
Wireless access points have limits on total bandwidth and number of simultaneous devices in use.

• Monitor settings may need to be adjusted if test items with shaded images (e.g., pie charts) are very light or cannot be seen.
• Monitor Resolution should be set to 1024 x 768 or better.• Students using small monitors or tablets may need to
scroll vertically and/or horizontally. The Zoom tool can be used to enlarge the content.
Appropriate Monitor Display
15
• The secure browser prevents students from accessing other computer or internet applications and copying test information during testing.
• Practice and training tests can be accessed with either the secure browser or with Chrome, Firefox, Safari, Internet Explorer, or most native tablet web browsers.
Secure Browser
16
• The Student Testing Site requires the use of a secure browser.
• The correct secure browser for each operating system must be downloaded and installed on all computers that will be used for student testing.

*The secure browser version that was installed for the Field Test is not valid for future assessments.
Installation Method:• Download the secure browser from your portal and install
it.• Download and save the secure browser onto a media
device (such as a flash drive), and copy and install the files on each computer.
• Download and save the secure browser to a network folder, and then copy and install the files on each computer.

• Voice technology must be available and functioning for students who require this accommodation.
• For Windows and Mac operating systems, default voice packs are generally pre-installed.
• Windows users may also choose to use the NeoSpeechTM
Julie voice pack for online tests. The Julie voice pack and installation instructions can be downloaded from TIDE.
• Linux users may need to install a Text-to-Speech package if one was not installed with the operating system.
