This page includes the following sections:

Students can access various tools during testing. The zoom tool is available through the TestNav apps, and others tools are made available during student registration. 


Students can zoom in and out on a test page using one of the following methods, depending on which TestNav app they use to test.

TestNav Desktop

  • In Windows:
    • Press Ctrl + to zoom in. 
    • Press Ctrl - to zoom out. 
    • Press Ctrl 0 to reset to default zoom.
  • In OS X or macOS
    • Press Cmd + to zoom in.
    • Press Cmd - to zoom out. 
    • Press Cmd 0 to reset to default zoom.

TestNav on Chrome OS

  • Press Ctrl + to zoom in.
  • Press Ctrl - to zoom out. 
  • Press Ctrl 0 to reset to default zoom.

TestNav on Android and iOS

To zoom, use two fingers on the screen and:

  • Pinch out to zoom in.
  • Pinch in to zoom out.

Accessibility Tools via Registration

After you register students and set access for accessibility tools, students may use them during their online tests. The videos below demonstrate how students interact with these tools. 

For details on configuring accessibility tool settings, see PNP Profile and Accessibility below.

Color Contrast

Students can set color contrast to view items more clearly.

Screen Reader

Blind or visually impaired students can use a screen reader to read the test content either with text-to-speech output or with a braille display.

American Sign Language (ASL)

Students can view a video with a person translating the item text to ASL.

Answer Masking

Students provided the option to use the Answer Masks tool can select it from the User drop-down menu. When selected, students see a mask covering multiple-choice distractors, with the option to click to expose each individually. They can turn answer masking on and off over each distractor or turn answer masking on or off on the entire question.


Line Reader Mask

Students provided the option to use the Line Reader Mask see the option in the User drop-down menu. This video shows the way the student views the Line Reader Mask when they select "Show/Hide Line Reader." Note that students can select text or select an answer choice within the Line Reader Mask window.


Text to Speech 

Text is read aloud to the student by means of the embedded text-to-speech software.

Play the second video for a demo of TTS with a graphic image.

Use your speakers/headphones to hear the TTS.

PNP Profile and Accessibility

The Personal Needs and Preferences (PNP) profile describes a student’s testing needs and preferences in a digital environment. A student's PNP profile tells the test delivery system what the needs are for that particular student. When an administrator registers a student, the registration system passes the PNP accommodation that the student needs to successfully test in TestNav.

The PNP profile is one area of the Accessible Portable Item Protocol (APIP™) standard, which aims to make tests and test items accessible for students with a variety of disabilities and special needs.

The registration system (like PearsonAccess or Aspire) needs to implement the API calls for PNP accommodations to work. 


Accommodations alter how items are presented, allowing students with disabilities to complete the same assignments as their peers. Accommodations do not alter assignment content, give students an unfair advantage, or change what a test measures. They do make it possible for students with certain disabilities to show what they know without being impeded by their disabilities.

Accommodations and PNP

 Three APIP areas — ContentPNP, and/or Delivery — control each accommodation. The table below illustrates which area controls each, as well as details when applicable. You can also expand the following section to view current accommodations, data, and scenarios.

Table Key

Add Time - Allows students additional testing time during a timed test. To give an student additional testing time, provide the addTime node in the registration APIs (before the student logs into the test), and include these settings:

  • support: "true"
  • mult (multiplier): 0 (zero) or a value in the 1.1-10.0 range

A 0 (zero) mult value causes the test to deliver a timed form or timed sections on a timed form without a timer. A 1.1-10.0 mult value results in that test form's timer value multiplied by the mult value. For example, a mult of 1.5 for a one-hour test results in the student having a 90-minute timer instead of a 60-minute timer.

Tests ignore the addTime node if:

  • The test is untimed.
  • Support is set to anything besides true.
  • Mult is set to any value other than 0 or a value in the 1.1-10.0 range.

Any changes you make to the addTime node after the student first logs into the test will also not affect the timer.

Answer Mask - Limits what students sees to help them focus on sections of text. Based on the PNP, multiple choice item choices are masked when the item is first presented. The student can turn masks on or off at any time.

Line Reader - Assists student to read content by moving a reading tool down line-by-line. Based on the PNP the registration system supplies.

Color Contrast (background/font color) - Allows student to choose a text and background color combination different from the default presentation. Helps students with visual discrimination problems. Based on the PNP the registration system supplies.

Available color choices include:

  • black-cream (black on cream)
  • black-lblue (black on light blue)
  • black-lmagenta (black on light magenta)
  • white-black (white on black)
  • yellow-blue (yellow on blue)
  • dgray-pgreen (gray on green)

Screen Reader - Allows students to use screen readers during secure tests. Only allows specified screen readers supplied in the PNP from the registration systems to run during secure tests.

For non-secure tests, screen readers are not restricted, and PNP settings do not have any impact.

Spell Check - Allows students to check their spelling within the rich text editor.

  • Five-function - Allows for a Five-function calculator calculator accommodation on a non-calculator section of a test.
