Collective Teacher Efficacy is not a slogan. It’s a system. John Hattie ranks Collective Teacher Efficacy as the #1 influence on student achievement—with an effect size of 1.57. But too often, it’s used as a buzzword without understanding what it really takes to create it. So what does it look like in action? 1. Common Goals + Shared Clarity “When educators believe that together they can impact learning, it becomes a powerful driver of success.” – Jenni Donohoo Schools with CTE don’t just have “mission statements”—they have laser-focused, measurable goals that everyone knows and works toward. That means: •Clearly defined learning outcomes •Aligned PLC goals •Instructional practices that are anchored in student data 2. Embedded Collaboration True collaboration isn’t just meeting together—it’s working together toward student outcomes. According to Donohoo, teams must: •Analyze student work regularly •Engage in joint problem-solving •Use protocols that focus on impact, not just planning This means moving beyond “what are we teaching?” to “what worked, for whom, and why?” 3. Leaders Who Create the Conditions Hattie and Fullan emphasize that leadership matters most when it builds teacher belief and action. That looks like: •Protecting time for high-quality collaboration •Modeling vulnerability and data-informed decisions •Celebrating progress based on evidence, not just effort 4. Evidence of Impact You can’t build efficacy without results. Teachers need to see: •Growth in student learning •Patterns of success from specific practices •Reflection tools that track progress over time Regularly asking: What is our evidence that students are learning better because of what we did? 5. Psychological Safety and Trust Without trust, CTE can’t exist. That means creating a culture where: •It’s safe to share failure •Staff value learning over looking good •Feedback is normalized, not weaponized. You don’t declare collective efficacy—you build it through systems, leadership, and focused work. When educators believe they can—and actually see they are—making a difference, the entire school moves forward. #CollectiveEfficacy #InstructionalLeadership #JohnHattie #Donohoo #PLCThatWorks #LeadingLearning #StudentImpact #SchoolCulture #TeacherGrowth @VisibleLearning @MichaelFullan1 @Jenni_Donohoo
