Ya, there are a few ways to approach this, but you’ll want to provide families with a unique student code or QR code. By inputting/scanning the code, a parent will be able associate their user profile row to the child account. The _easiest_ way to do this is write a new record to a “parent-student association” table that includes both the user id and the student id, but it might not be scalable since many adults can be associated to the same child. A leaner approach would be to write the student id to an array column in the user profile table, but this is a trickier setup. It involves using inline arrays using what we call the “Trebuchet method”. I plan on making a tutorial video on inline arrays as soon as Glide supports JSON in inline arrays. Until then maybe a combo of these two videos will help: This video uses a slightly outdated trebuchet setup, but the concept still works > [@dizzy The Trebuchet Method](https://community.glideapps.com/t/the-trebuchet-method/48325): > > In certain situations, a single column has the potential to replace an entire table of data. The Trebuchet Method allows you to create an inline array that allows you to create a SIMPLE one-to-many relationship between two sets of data without the need of a log or submissions table. Examples: Who owns which item Who has registered for an event Who has completed which task Pros: no app bloat no additional rows of data fairly easy to set up Cons: Can only track one data point (eg. who has w… > [@selfie Populate a Form by Scanning a QR Code](https://community.glideapps.com/t/populate-a-form-by-scanning-a-qr-code/69957): > > v Hey fellow Gliders!
