# Baseline measurement checklist

|| During the baseline measurement we measure – completely anonymously – how students use school devices to go online. No content, only behavioural data: how often, how long, which category. This gives you insight into digital behaviour at school.
### Technical requirements for a correct baseline measurement

1. The school's IP addresses must be entered correctly in Basispoort.
1. [Myndr must be activated in Basispoort](/en/article/activating-myndr-in-basispoort-2skaa2/).
1. [Incognito windows must not be available](/en/article/does-the-extension-also-work-in-incognito-windows-18vw1j1/).
1. Signing in with private accounts must not be possible. ([Chromebooks](/en/article/prevent-signing-in-to-a-chromebook-with-a-personal-google-account-1sufs0h/) / [Windows](/en/article/prevent-signing-in-to-a-windows-laptop-with-a-personal-microsoft-account-8zuasi/))
1. The Myndr extension must be installed. ([Chromebooks](/en/article/installing-the-extension-on-chromebooks-for-use-with-basispoort-google-workspace-ilhz1h/) / [Windows](/en/article/installing-the-extension-on-windows-laptops-for-use-with-basispoort-microsoft-in-2fiect/))

Once these requirements are met, you can test Myndr on a student laptop by going to [test.myndr.net](https://test.myndr.net).
