If you have created a Google Form it can be tricky to allow others to make a copy of your Google Form. If you have created a Google Form to collect attendance, as a daily warm up or a formative assessment you may want to share what you made with another teacher. Most likely you do not want other teachers data mixed in with your data. You want the teachers to copy your Forms not use your Forms.
In the edit screen of the Google Form there is no option to give view only access. Click on the File menu and choose “Add collaborators…”
Instead of trying to to share the edit screen of the Google Form, instead share the spreadsheet.
Make a Copy
Assuming you do not want other teachers to view and copy your data in your spreadsheet I recommend you use the File menu to make a copy of the spreadsheet. Delete all of the response data out of the spreadsheet. This copy is your template to share the Google Form.
If you change the end of the spreadsheet URL from /edit to /copy the URL will prompt someone to make a copy of the spreadsheet.
