Sparx connects to your MIS and allows you to import classes into your Sparx Science site.
Once classes are imported, the students are kept in sync with your MIS automatically every night. So if a student moves class in your MIS, this change will be reflected in Sparx the next day.
Currently the MIS connection is managed through Sparx Maths so if this your MIS is not connected to Sparx you'll need to speak with your Maths department and MIS administrator.
What's an MIS?
Schools use management information systems (MIS) to store student and class data. Schools use different systems but the most common are Bromcom, Arbor & SIMs.
