It would be useful to be able to set default notification settings according to pupil year group and type of visit. For older pupils it isn't necessarily appropriate to send emails home detailing visits etc to the medical centre.
For example, for sixth form pupils a default "no notifications" (with the option to override in the case of permission granted or emergency) might work best for most types. Then staff need to think before sending something home. The section could include a column for pupil consent given/not, or this could sit on the main record and come up when attempting to send a notification?
