33 Preparing for Testing: TestNav Online Testing Platform

34 TestNav Takeaways Step 7 What are the TestNav Technology Dependencies?
What are TestNav Best Practices and Recommendations? What do I need to know about wireless testing? What are Student Response Files (SRFs)? What directory permissions are needed for TestNav? Section Resources Hardware and Software Requirements link for TestNav 7 TestNav 7 Technology Guidelines Step 7 Copyright © 2013 Pearson Education, Inc. or its affiliates. All rights reserved.

35 TestNav Technology Dependencies
Firewalls, content filters and spam filters must allow the Pearson domains Minimum Screen Resolution of 1024 x 768 is required Browser Dependencies: Adobe Flash Player version 10 and higher Java runtime plugin version 1.5 and higher Windows Firewall configured to allow javaw.exe to communicate Allow pop-ups for Pearson sites Accept Java applet Allow Local File access to home directory Complete requirements can be found at Note: Pearson continually monitors and evaluates the hardware and software requirements. As vendors release newer versions of their products, we update the recommended requirements accordingly. Copyright © 2013 Pearson Education, Inc. or its affiliates. All rights reserved.

36 Best Practices and Recommendations
Performance: Use Proctor Caching for best network performance. Use System Check extensively to test Proctor Caching and network environment before live testing. Use System Check to test wireless network capacity if using wireless clients. Testing Computers: Use System Check (TestNav Verification Test) to validate that TestNav will load on machines. Freeze browser, Adobe Flash Player, & Java environment if possible. Energy Saving features can interrupt testing, so the recommendation is to set those to not trigger during the length of the test. Copyright © 2013 Pearson Education, Inc. or its affiliates. All rights reserved.

37 Best Practices and Recommendations
Testing Computers: Applications that launch automatically Any applications that may automatically launch on a computer should be configured not to launch during testing sessions. Common applications that may launch automatically include: Anti-virus software performing automatic updates Power management software on laptops warning of low batteries Screen Savers with Auto message notification Copyright © 2013 Pearson Education, Inc. or its affiliates. All rights reserved.

38 Best Practices and Recommendations
For wireless testing: Wireless access points – more is better Distance – closer is better Limit the number of computers per wireless access point Try a small number first for proof of concept Do not roll out a few hundred on the first attempt (baby steps) Limit obstructions Use the System Check Utility to verify that you have the appropriate amount of bandwidth for online testing Copyright © 2013 Pearson Education, Inc. or its affiliates. All rights reserved.

39 TestNav Directories TestNav creates a Pearson directory in the home directory of the testing computer: Windows XP C:\Documents and Settings\username\Pearson\... Windows Vista and 7 C:\Users\username\Pearson\... Mac //Users/username/pearson/... Student Log files: Pearson/student/logs SRF file default location: Pearson/student/srf TestNav and test content is temporarily stored locally: Pearson/temp Pearson recommends that the Pearson directory be excluded if desktop restoration tools such as DeepFreeze are used Copyright © 2013 Pearson Education, Inc. or its affiliates. All rights reserved.

40 Student Responses TestNav will save student responses to an encrypted backup file so the student can either continue testing or exit the system without losing response data. TestNav requires at least one working save location TestNav by default saves student response data to: <home dir>/Pearson/student/srf Create a TestNav Config to specify custom Primary and Alternate file locations Pearson recommends designating two Response File Save Locations Best Practice: Primary Response File Location should be on the student workstation. The alternate Response File Location should be on a shared network location Students must have full access to designated Response File Locations Copyright © 2013 Pearson Education, Inc. or its affiliates. All rights reserved.

41 Student Response Files (SRF) SRF file configured for network and local save locations
Response file will be saved to both the individual student’s testing workstation and a network location Student may resume on any workstation that has access to the shared network save location Copyright © 2013 Pearson Education, Inc. or its affiliates. All rights reserved.

42 Student Response Files (SRF) SRF file configured for local save locations only
All response files will save only to each individual student’s testing workstation Student must resume on the same workstation or SRF files must be moved to the workstation where the student will resume the test If the SRF files are not placed in the same location on the new workstation TestNav will prompt the student to navigate to where the SRF files are saved when they resume testing Copyright © 2013 Pearson Education, Inc. or its affiliates. All rights reserved.

43 Student Response Files (SRF) SRF file configured for network save location(s) only
Response files will save to one or more network locations Student may resume on any workstation that has access to the shared network save location(s) Copyright © 2013 Pearson Education, Inc. or its affiliates. All rights reserved.

47 Providing Support during Testing: Early Warning System & Quick Reference Guide

48 Early Warning System Takeaways
What is the Early Warning System? What are the TestNav Early Warning System Triggers? How do I resolve Early Warning System alerts? Section Resources Early Warning System User Guide Please make this relevant to DTCs. They need to know this because they may be providing support during testing. Copyright © 2013 Pearson Education, Inc. or its affiliates. All rights reserved.

49 Early Warning System (EWS)
The Early Warning System (EWS) is integrated functionality that gives TestNav a high degree of fault tolerance and provides additional fail-safes in the event of unexpected network disruptions during online testing. Copyright © 2013 Pearson Education, Inc. or its affiliates. All rights reserved.

50 Early Warning System Design
Minimal interruptions for students Multiple physical file backups to safeguard against data loss Notification Screens designed for Test Proctors Early Warning System notifications often involve IT staff so an understanding is necessary to correct any issues during testing Copyright © 2013 Pearson Education, Inc. or its affiliates. All rights reserved.

51 Student Responses – SRF Files
The EWS writes continuously in the background to the student response files. Both the Primary and Alternate files are written to at the same time. The SRF file has a response data threshold that once reached will trigger TestNav to send response data to Pearson. Uploading of response data is continuous. If an upload fails TestNav will cycle and attempt another upload. If the response data upload is successful, TestNav will create a new empty SRF file and begin the process again. TestNav will only delete an SRF file once it is successfully uploaded. Copyright © 2013 Pearson Education, Inc. or its affiliates. All rights reserved.

52 Student Responses - Identification
A combination of the test ticket ID combined with the session token is used to uniquely identify a Student Response File (SRF). TestNav can identify the correct student response file if a test is successfully resumed. The SRF can only be used the next time the student resumes a test. Copyright © 2013 Pearson Education, Inc. or its affiliates. All rights reserved.

53 TestNav Early Warning System - Triggers
Scenario 1: TestNav determines that neither Saving Response File Location is viable. Will result in immediate Test Proctor Click Here notification. Scenario 2: TestNav is unable to download portions of the test. Scenario 3: TestNav is unable to upload student responses to Pearson. Will result in Test Proctor Click Here notification at the time of test submission. Copyright © 2013 Pearson Education, Inc. or its affiliates. All rights reserved.

54 TestNav EWS – Test Proctor Click Here Screens
One of the following screens will appear when scenario 1, 2 or 3 occurs. Students should ALWAYS raise their hand when presented with either of the Test Proctor Click Here screens. They should NEVER click the Test Proctor-Click Here button. Copyright © 2013 Pearson Education, Inc. or its affiliates. All rights reserved.

55 TestNav EWS – Scenario 1 In this scenario there is an issue with both of the Response File Locations. Either the student does not have full access to the location(s), OR the location(s) are temporarily unavailable. Resolve by entering and saving a viable Response File Location. If the issue is temporary, reselect the original location. Then, click the Save and Continue button. Best Practice: Contact your local Technology Coordinator to determine the appropriate course of action. Copyright © 2013 Pearson Education, Inc. or its affiliates. All rights reserved.

56 TestNav EWS – Scenario 2 In this scenario, TestNav cannot access the test content on the student work station. If Proctor Caching is being utilized, either the Proctor Caching Server is not functioning properly, OR the local network and Pearson are not communicating. The ONLY way to resolve this situation is to click the “Close TestNav” button. The student’s testing status will remain as STARTED in PearsonAccess™. Once communication is restored, Resume the student in PearsonAccess and have the student log back into TestNav. Best Practice: Your local Technology Coordinator should be contacted to determine the appropriate course of action. TestNav makes several attempts to access the test content. This message indicates all attempts to retrieve test content have failed. Copyright © 2013 Pearson Education, Inc. or its affiliates. All rights reserved.

57 TestNav EWS – Scenario 3 In this scenario not all of the student responses have been received by the Pearson testing server. However, responses not received by Pearson have been saved locally to the Primary Response File Location. You may try to resolve this scenario by clicking the Retry button until the submission of responses is successful or click on Close TestNav Best Practice: If clicking the Retry button does not resolve the situation, contact your local Technology Coordinator to determine the appropriate course of action. TestNav makes several attempts to communicate with the Pearson Testing Server. This message indicates attempts to submit some or all of the student responses have failed. Copyright © 2013 Pearson Education, Inc. or its affiliates. All rights reserved.

58 Quick Reference Guide The Quick Reference Guide should be available to all test proctors to help support students as they test. The Guide provides a list of all the warning messages that TestNav may show a student and how to resolve them.
