There is also a Statewide ELC which is linked here: Statewide guarantee | UC Admissions
Once the student submits their UC application, you can log back into the UC application and then go to the link that says “View how your application is viewed” it should show if the student is ELC eligible. A student can be both Local and Statewide ELC but it will only show that they are ELC on the application.
Some HS’s will notify their students if they are ELC eligible (Local).
