As previously mentioned, Parent Codes are automatically generated for each pupil. It is possible, however to generate a new Parent Code for each pupil.
If you choose to generate a new Parent Code for a pupil, the previous Parent Code will no longer be useable for any new registrations.
Generating Parent Codes In Pupils Area
Select the pupils you wish to generate a new 'Parent Code' for and the click on the purple menu button 
selecting 'Generate Parent Codes' from the list.
It is possible to also generate a new 'Parent Code' in an individual pupil's record by selecting a pupil and clicking on the 'Edit' button. In the 'Edit Pupil' screen click on the 'Generate' button next to the Parent Code field. Here a new Parent Code will be generated with a message to confirm this is the case.
