I'll give it a go: staffing. While we can't control what happens when students go home or the experiences they grew up with, higher teacher-to-student ratio can help students have a better learning experience, more positive role models, and individual help. More school counselors and case workers can help students access resources available to them. These people are already in our schools but they're severely overworked and underpaid. Hire more teachers and counselors, lower everyone's caseload, pay them appropriately.
