To help students understand what internships could be available to them, the Work-Based learning tab pulls opportunities from Indeed that would be relevant for students.
For most districts, this list is populated with opportunities posted to Indeed with the job type of "Internship." The opportunities that are closest to your school district will display first. 
If your district has purchased the additional WBL License, you will also have the chance to apply to other local opportunities.
