Lead Spark Team is built on collective teacher efficacy—the shared belief that teachers working together can create meaningful change for students.

According to John Hattie's meta-analysis of 1,400+ studies, collective teacher efficacy has a 1.39 effect size—the highest of any educational intervention.

That's equivalent to 3+ years of student growth in a single school year.

When teachers work together on real challenges, test research-backed strategies, and see measurable results, they build:

• Competence to solve instructional problems
• Confidence in their collective ability
• Capacity that lasts beyond any single initiative

We don't guess. We build on what's proven.
