Within a student record, where the parental contacts are recorded there is an option for ‘Correspondence’. The Parental Correspondence on a contact should be set for those parents who do not live with the student and who wish to receive correspondence and/or a copy of the pupil report.
“It is not currently possible to bulk update correspondence for contacts, we expect this to be used for parents who do not live with students but want to receive correspondence for them so I suspect this is why there is not a bulk update routine. Patch 11928 sets all Parental Correspondence and Pupil Report flags to False for every record in SIMS – this includes students who are no longer on roll. The patch will not exclude anyone.”
The above is a statement from Capita as of 01/03/2018.
