One of the things I’m doing this year is helping to our entire calendaring system over to Google Calendar. This is a significant undertaking, since many of our calendars are really just lists of dates and assignments, and as a boarding school, we have a number of “duty calendars”, like ER Driver that need to be transformed from paper documents into electronic calendars.
The good news is once you get this information into google calendars, the sky is practically the limit in terms of what you can do with Google scripting. I’ve managed to set up the ER driver calendar so that it sends out a reminder both the week and day before you are on duty to confirm you’ll be taking on this duty. You can even set up mail merge style emails.
It seems to me like this would be great for creating a google form for reassessments that also reminds students about the reassessment they signed up for.
