To improve the security of Chromebooks, we have developed two different options for locking the device. You choose between these options, but it is important to note that both require a managed Chromebook, i.e. one that has been Enterprise enrolled with a Chrome Education Upgrade license.
- Option A - Install the app “Trelson Assessment Kiosk-app”
- Option B - Install the extension “Trelson Assessment Focus”
Prerequisites
For everything to work the following requirements must be met:
- The students' Chromebooks are managed, i.e. they are Enterprise enrolled with Chrome Education Upgrade licenses. For details see Google Help Article.
- Check that the Marketplace app “Trelson Assessment” is installed in the Organizational unit where the students' accounts are located. This is needed in order for the app "Trelson Assessment Kiosk-app" to get the right permissions. For details see the separate help article “Install the Marketplace app”
Option A - Install the app “Trelson Assessment Kiosk-app”
Install the Trelson Assessment Kiosk-app:
- Open the admin console in the Google Chrome web browser by going to the admin.google.com page.
- Sign in with an administrator account for your Google Workspace for Education domain.
- Go to Devices > Chrome > Apps and extensions > Kiosks.
- Select the Organizational unit where the students' Chromebooks are located.
Hint: The policy that is set is inherited down the organizational structure. It is fine to choose a top organization. - Click on the yellow plus sign and choose to install from Chrome Web Store.
- In the search box type Trelson Assessment Kiosk-app and press Enter.
Hint: It is also possible to search for the app's unique ID. In the box Show app by id copy and paste ohloljpcehjlmnijelgcmenkmogmdnlh - Click on the app to mark it and click on Select to install it.
- After installation, the following image will appear where options Allow on-screen keyboard and Enable plug-ins are enabled.
- The app will now automatically install on students' managed Chromebooks.
Attention: Keep in mind that the app Trelson Assessment Kiosk-app is installed on the Chromebooks that are in the selected Organizational unit and not based on which user accounts are in this Organizational unit.
Option B - Install the extension “Trelson Assessment Focus”
Through the extension Trelson Assessment Focus, we can control most of ChromeOS, but some settings will need to be made manually in your Google Workspace for Education domain to guarantee security. Note that the extension only works for ChromeOS.
Change the settings needed for the Trelson Assessment Focus add-on:
- Open the admin console in the Google Chrome browser by going to the admin.google.com page.
- Sign in with an administrator account for your Google Workspace for Education domain.
- Go to Devices > Chrome > Settings > Users and browsers.
- Select the Organizational unit where the students' accounts are located.
Hint: The policy that is set is inherited down the organizational structure. It is fine to choose a top organization. - Under the heading User experience policy Multiple sign-in access should be set to Block multiple sign-in access for users in this organization.
- Under the heading User experience the policy Developers tools should be set to Never allow use of built-in developer tools.
- * (Optional) Under the heading Security the policy Incognito mode should be set to Disallow Incognito mode. See the explanation below.
* (Optional) Use Trelson Assessment Focus with Incognito mode enabled
If the school wants the students to have access to Incognito mode on their Chromebooks, this is set by choosing Allow incognito mode by an administrator according to point 7 above in the Organizational unit where the students' accounts are located.
- When the students start their exam, they will be greeted by a dialog box that says HELP instead of the option to open an exam.
- When they click on HELP they will get a dialog box with a link to click on.
- The students are then sent to the settings for the extension Trelson Assessment Focus where they must activate Incognito mode.
- Now the students have made the setting and the extension Trelson Assessment Focus will also be active in Incognito mode.
Android apps
Unlike regular apps in Chrome, we can't control Android apps. If the school has chosen to install certain Android apps that students can use to cheat during exams, these apps need to be turned off.
Change policy for Android apps:
- Open the admin console in the Google Chrome browser by going to the admin.google.com page.
- Sign in with an administrator account for your Google Workspace for Education domain.
- Go to Devices > Chrome > Apps and extensions > Users and browsers.
- Select the Organizational unit where the students' accounts are located.
Hint: The policy that is set is inherited down the organizational structure. It is fine to choose a top organization. - Click on the Android app and select Block.
