Schools spend heavily on discipline policies meant to curb bad behavior among students already facing tough odds. Quantitative research keeps pointing to a simpler starting point that delivers bigger returns: making sure those students feel they belong.
Numbers from large-scale surveys show clear patterns. When at-risk youth report stronger ties to their school community, rates of substance use, mental health struggles, and safety-related absences drop across the board.
Take the 2021 Youth Risk Behavior Survey data covering U.S. high school students. Roughly 61.5 percent said they felt connected to others at school. Those who did reported markedly lower levels of every risk behavior tracked, from marijuana use to experiences of forced sex.
The gaps were consistent. Poor mental health sat at 22 percent among the connected group versus 40.1 percent among those who did not feel connected. Lifetime prescription opioid misuse stood at 9.6 percent versus 16.8 percent. Similar differences appeared for unprotected sex and skipping school out of fear.
Associations held for most demographic slices, though strength varied by race, ethnicity, and sexual identity in a few cases.
Another set of findings comes from longitudinal tracking of at-risk students. A 2024 study published in Child & Youth Services Review followed four waves of data and applied structural equation modeling. It found that school suspension carried consistent negative effects on long-run educational outcomes.
The mechanism ran through worsened perceptions of the school environment, which in turn linked to poorer academic and behavioral results down the line. Suspension did not simply remove a problem; it appeared to compound it for the very students targeted.

Here's the catch. Many interventions still default to removal or punishment because they feel immediate and measurable in the short term. Yet the same datasets show that engagement-focused approaches often produce higher participation rates among at-risk youth. Technology-based programs, experiential therapies, and structured after-school initiatives posted stronger engagement numbers than traditional counseling alone in one rapid review of the literature.
The difference matters in practice. Programs that keep students showing up create more opportunities for the protective effects of connectedness to take hold. Removal severs those opportunities.
Broader patterns emerge when researchers zoom out. School connectedness protects against co-occurring risks, not just isolated behaviors. Students who feel adults and peers care about them show lower prevalence across mental health, substance, sexual, and safety domains simultaneously.
That overlap suggests single-issue fixes miss the mark. A student missing school because of feeling unsafe may also carry elevated risks in other areas; addressing the connectedness gap can shift multiple indicators at once.
Global data remain patchier than U.S. national surveys, yet the core logic travels. Countries tracking similar risk behaviors in secondary schools report parallel protective roles for belonging and adult support. The precise percentages shift with local context, but the direction of the relationships stays consistent.
Implementation still varies. Some districts layer connectedness efforts onto existing schedules through advisory periods or peer mentoring. Others embed them in curriculum redesigns. Success hinges less on the label and more on whether students experience genuine care and inclusion rather than another mandated activity.

Researchers tracking these outcomes emphasize measurement discipline. Quantitative designs that follow the same students over multiple years reveal effects that cross-sectional snapshots miss. They also highlight where associations weaken, such as for certain subgroups where additional barriers persist.
One consistent takeaway from the longitudinal work is that perceived environment matters as much as the policy itself. Changing rules without shifting daily interactions leaves the underlying drivers untouched.
Practical steps follow directly from the patterns. Schools can audit current discipline data against connectedness measures to spot where removal correlates with later problems. They can test low-cost additions like regular check-ins or interest-based groups that build ties without requiring new budgets.
The evidence does not promise overnight transformation. It does show that ignoring the belonging piece reliably undercuts other efforts.
