Can you tell me some resources that I can use to know how to help homeless students?
You can check on our website the page Identifying and Supporting Students Experiencing Homelessness from Pre-School to Post-Secondary Ages. There you can find useful information in this regard.
What is it taken into consideration when evaluating an student eligibility for federal student aid?
First, there's no income cut-off to qualify, and many factors such as the size of the student's family and their year in school are taken into consideration.
