The ROI Question
Every dollar spent on one program is a dollar not spent elsewhere. Measuring intervention effectiveness isn't just academic—it's essential stewardship of resources that could be used to help students in other ways.
The tutoring program cost $200,000 annually. Leadership assumed it worked—students seemed to like it, teachers reported improvement. But when the district finally measured outcomes, they found no significant difference between tutored students and similar non-tutored peers. Two hundred thousand dollars for no measurable impact.
Measuring Effectiveness
Define Success Metrics
Before launching, define what success looks like: assessment gains, attendance improvement, behavior reduction, graduation rates. Specific, measurable outcomes enable evaluation.
Establish Baselines
Measure starting points before intervention begins. Without baselines, you can't quantify change.
Create Comparison Groups
Compare intervention participants to similar non-participants. Improvement without comparison could reflect natural growth, not program impact.
Track Implementation
Document what actually happened: Who participated? How much? With what fidelity? Poor implementation can undermine even evidence-based programs.
ROI Calculation Framework
ROI = (Value of Outcomes - Cost of Intervention) / Cost of Intervention
Costs to Include
- • Staff time and salaries
- • Materials and supplies
- • Training costs
- • Technology/platforms
- • Opportunity costs
Outcomes to Value
- • Achievement gains
- • Graduation improvements
- • Reduced remediation
- • Behavior improvements
- • Long-term benefits

Common Evaluation Challenges
Selection Bias
Students in interventions often differ from non-participants in ways that affect outcomes. Control for these differences when comparing.
Attribution
When outcomes improve, was it the intervention or something else? Multiple factors affect student success simultaneously.
Time Horizons
Some benefits appear quickly; others take years. Early literacy interventions might not show full value until high school graduation.
Valuing Outcomes
Putting dollar values on educational outcomes is imprecise. What's a test score gain worth? A prevented dropout? Use research-based estimates carefully.
Making Data-Driven Decisions
The district discontinued the ineffective tutoring program and invested in high-dosage tutoring with evidence of effectiveness. The new program cost more per student but served fewer students with demonstrable impact.
That's ROI thinking: not just asking "Does it work?" but "Does it work well enough to justify this investment over alternatives?"

Key Takeaways
- Define success metrics, establish baselines, and create comparison groups before launching interventions.
- Include all costs: staff time, materials, training, technology, and opportunity costs.
- Address challenges of selection bias, attribution, and time horizons in evaluation design.
- Use ROI analysis to allocate limited resources to interventions that actually work.
