About Desmos Test Mode

Desmos partners with high-stakes test providers in over 30 states and on several national exams to provide access to our calculators on testing day.

To help students and teachers prepare for these assessments—and to support delivery of lower-stakes tests and quizzes in classrooms—we've developed a suite of "Test Mode" apps.

Each app lets you administer low-stakes, proctored assessments with security features to help enforce your school's or classroom's policies. We also partner with Mobile Device Management (MDM) companies to provide an even more secure test-day experience.

This page describes the various levels of security available through our apps, along with instructions for installation and usage.

Practice

Students can practice using the calculators on our Practice Page. We also provide free apps for Chromebooks, iPads, and iPhones to support practice.

Our practice apps match the configuration that students will encounter on test day. Students can practice for a specific assessment by selecting "Choose Assessment" on the opening screen.

Chromebooks

Our Chrome app allows for offline practice. You can download the Chrome app by visiting bit.ly/desmos-test-mode-chrome-app on the device. The Chrome browser must be installed on the device to use the Chrome Test Mode app.

Kiosk mode provides an extra level of security by preventing other apps from being used while the calculator is open. Before you sign in, click “Apps” on the bottom bar and then select Desmos Test Mode. To exit kiosk mode, turn the Chromebook off.

While in kiosk mode, the top bar of the calculator will change color according to the calculator in use: green for graphing, purple for scientific, blue for four function. There will also be a badge next to the Desmos logo.

Please note that students can leave the app by powering down their Chromebook and restarting it. You can monitor appropriate usage by looking at the log at the conclusion of the test. It will show how long the student was continuously in the application.

iPads and iPhones

Our iPad and iPhone app allows for offline practice. The app also supports additional levels of security.

Students can opt into App Self-Lock by pressing the "Start Test" button. This will prevent other applications from being used.

This will lock the device to that app and won't allow the student to leave it without a code.
