Create a Weekly Checklist

JetCert Forms is a very basic form submission app and doesn't have any automation or many of the features you might expect. If the form is the same each week you will need to save it as a template and manually adjust it each week. On your specific points:

1. Automatically send the Form invite to the whole group on a Monday morning
Forms doesn't have any method for sending out a form automatically. For this you would need a build a simple flow in Power Automate that runs every monday morning and sends out an email with a link to the form.

2. Set a Form deadline of 7 days

In the form settings you can set the start date and end date but would need to do this manualy each week.

3. Only allow one form completion (by any group member) per week

There is no feature that allows this. You can set the form to only accept 1 response per person, but not restrict it to 1 response per group of people.

What we always do with our Forms is to use a flow in Power Automate to save each form response into a SharePoint list and send out email confirmations etc. This is so we can give ID nubers and other info to our staff once they have submitted a form, but also for backup and audit reasons.  You could get the flow to check if a form has already been submitted for this week and not save it if it has.
