You can set a date after which parents will not be able to submit their Slip.
When adding or editing creating a new Slip, click the 'More' link to open the additional options available for a Slip.
To enable a Closing Date, check the box, then set a date.
Parents will not be able to respond from midnight of the date a Slip is set to be closed.
(i.e If the date is set for today, then Parents will not be able to respond from tonight after 11:59 PM)
