Proctor Caching for TestNav
Overview
Proctor Caching for TestNav
Proctor Caching is Pearson-supplied software that is
used in conjunction with TestNav to reduce
bandwidth requirements and accelerate the delivery
of test content.
• Allows you to pre-cache test content to your local network
before a test.
• Reduces the burden on your ISP by eliminating redundancy
in requests for test content.
• Stores an encrypted local copy of all pre-cached tests.

PearsonAccess and Proctor Caching Setups
• TestNav Configurations work from school to district. A
School Proctor Caching machine will take precedence over a
District. If a School does not have a setup, then the District
setup will apply.
• The Proctor Caching Server option in Session Details will
show only if there are two or more Proctor Caching machines
to choose from at the School or District.
• Sessions created prior to setup will state “No server
assigned”. You can use the Apply TestNav Configuration
option and Edit Session to choose a specific Proctor Caching
machine.

22
Pre-Caching Test Content
• For EVERY Proctor Caching Server, EVERY form must be cached at
least once.
– Example: If you have 6 math (main form) sessions that use the same
Proctor Caching server, you only have to cache one session.
– Example: If you have 6 math (main form) sessions, and 2 math (audio)
sessions that use the same Proctor Caching server, you have to cache each
session type once.
– To verify that you have cached the needed forms, the Proctor Caching
Diagnostic tool can be used.

TestNav
Online Testing Platform
Early Warning System
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 © 2011 Pearson Education, Inc. or its affiliates. All rights reserved.
49
Early Warning System Design
• Minimal interruptions for student.
• Multiple physical file backups to safeguard against data loss.
• Notification Screens designed for Test Proctors.
Copyright © 2011 Pearson Education, Inc. or its affiliates. All rights reserved.
50
Student Responses
EWS 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:
Pearson/student/srf
– Create a TestNav Config to specify custom Primary and
Alternate file 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.
Pearson recommends designating two Response File Save Locations.
Copyright © 2011 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 © 2011 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 © 2011 Pearson Education, Inc. or its affiliates. All rights reserved.
53
TestNav Early Warning System - Triggers
Situation 1:
TestNav determines that neither Response File Location is
viable.
– Will result in immediate Test Proctor Click Here notification.
Situation 2:
TestNav is unable to download portions of the test.
– Will result in immediate Test Proctor Click Here notification.
Situation 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 © 2011 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 situation 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 ProctorClick Here button.
Copyright © 2011 Pearson Education, Inc. or its affiliates. All rights reserved.
55
PearsonAccess – Resume Test Functions
PearsonAccess will automatically
determine whether a student’s test
should be resumed or resumed with
file.
•
•
•
Users will only be able to select
“Resume Test” when resuming a
student’s test.
If the student is in Active status, the
system will Resume with File, and
the “Resumed-Upload” status will
display on the Session Details
screen.
If the student is in Exited status, the
system will resume without looking
for a student response file, and the
“Resumed” status will display on the
Session Details screen.

56
Best Practices and Recommendations
– Use Proctor Caching for best network performance.
 Available for installation now.
– Use System Check extensively to test Proctor Caching and
network environment before live testing.
 Recommended at least one week prior to testing
 Use the System Check (TestNav Verification Test) on each
testing computer to validate that TestNav will load on
machines
– Use System Check to test wireless network capacity if using
wireless clients.
 Recommended at least one week prior to testing
Copyright © 2011 Pearson Education, Inc. or its affiliates. All rights reserved.
57
Best Practices and Recommendations
• Testing Computers:
– Disable all applications that launch automatically
(Recommended at least one week prior to testing)
 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
Email with Auto message notification
Systray icons if clicked by the student can cause TestNav to exit.
• Backup Save Locations:
– Specify a local save location for the Primary.
– Specify a network share for the Alternate.
