The spell check routine should use the pupil data to check pupil names. Many teachers make mistakes when writing reports that are not picked up by the spell check or other members of staff. These can easily be caught by checking against the pupil iSAMS record.
These errors are visible to parents and so very embarrassing.
I had someone on Senior Leadership asking me yesterday afternoon if this was possible. Looks like it's still not possible, but would be a great thing to have.
I think having a dropdown list in settings somewhere giving us the choice between spell checking on just Forename or on the Preferred Forename (or both) would be good. Some schools may insist on using the formal name, some may be happy with the preferred name.
