The Problem We're Solving
Districts can't predict who will actually succeed in their schools using traditional hiring methods — and AI has made this harder, not easier.
Everyone Looks the Same on Paper
AI-optimized resumes make credentials blend together. Resumes show where someone has been — not how they think, lead, or problem-solve when it matters most.
Volume Without Insight
High-volume hiring forces panels to spend less time per candidate exactly when they need to be more discerning. The best talent gets lost in the stack.
Bias Thrives Under Ambiguity
Rushed screening and similar-looking candidate pools force hiring teams to rely on gut instinct — the exact moment bias shapes decisions. Research shows interviewer decisions are often made within the first 30 seconds based on appearance and confidence, not capability.
What Makes TruFit Different
We Observe Demonstrated Behavior in Context
We evaluate how candidates actually think, decide, and communicate in role-relevant simulations. This reveals performance potential grounded in observable behavior — not just credentials or interview polish. The best predictor of job performance is performance on that same job.
We Can Assess Every Candidate
Historically, deep behavioral assessment was limited to a small finalist group. TruFit enables districts to evaluate entire applicant pools with consistent analysis — bringing high-quality behavioral insight to every candidate, not just a select few.
Transparent, Traceable Talent Decisions
Every assessment produces a documented, structured record — bringing transparency, consistency, and traceability to hiring decisions. Leaders can explain and stand behind their choices with evidence rather than instinct.

Schools Struggling to Hire
of U.S. public schools report challenges hiring qualified teachers. The crisis is widespread and worsening.

Research-Based Screening
of principals use research-based screening assessments. The remaining 97% rely on resumes and unstructured interviews.

Interview Bias
Interviewer decisions are made within the first 30 seconds based on appearance, confidence, and likability, not teaching ability.

Teacher Impact
Teachers have two to three times the impact on student achievement than any other school factor, including programming, leadership, facilities, and technology.

Predictive Interviews
of principals use research-based predictive interviews, meaning 98.87% rely on gut feelings and bias-prone methods.

Cost of Turnover
Teacher turnover costs $10,000–$26,500 per teacher. Bad hires impact student outcomes and school culture.

Aurora Public Schools
When Aurora Public Schools sought to transform their approach to talent, they partnered with TruFit to bring evidence-based insight into their hiring and development process.
"Transformed how Aurora Public Schools understands talent. TruFit gave us a framework that goes beyond resumes and interviews. We now have real, actionable data about what our people are capable of."
What leaders are saying
We were able to see a much fuller picture of their leadership strengths and styles. The depth of insight was remarkable. It showed us things interviews simply can't.

Head of School, Saigon South International School
Clear, evidence-based insight that gave us confidence beyond what traditional interviews alone could offer. We knew we were making the right decisions.

Director, Kazakhstan International School
Partnering with TruFit transformed our recent search for a High School Principal into a far more insightful and effective process.

Frequently Asked Questions
What is evidence-based hiring in K-12 education?
Evidence-based hiring in K-12 replaces subjective resume screening and unstructured interviews with validated assessment methods that actually predict teacher and leader effectiveness. Despite 86% of U.S. public schools reporting hiring challenges (NCES, 2024), only 2.93% of principals use research-based screening tools (Kimbrel, 2019). Evidence-based hiring closes that gap by applying methods proven through decades of industrial-organizational psychology research to the unique context of schools and districts.
How does predictive hiring improve outcomes in education?
Predictive hiring in education uses assessment methods with demonstrated validity to identify candidates who will actually succeed in the role, not just candidates who interview well. Structured interviews predict .44 to .57 of job performance, and simulation-based assessments predict .42 to .54, compared to just .19 for unstructured interviews (Sackett et al., 2022; Schmidt & Hunter, 1998). Districts using TruFit's predictive approach have seen a 9.8% reduction in first-year teacher turnover and 8.4% improvement in early-career teacher effectiveness ratings.
How can school districts reduce teacher turnover?
Districts can reduce teacher turnover by hiring teachers who are genuinely well-matched to the role and school context from the start. Teacher turnover costs approximately $26,500 per teacher (Learning Policy Institute), and much of it stems from poor initial fit that no amount of onboarding can fix. TruFit clients have achieved a 9.8% reduction in first-year teacher turnover by using simulation-based assessments that reveal candidate-role fit before a contract is signed, not after problems emerge.
What research supports TruFit's approach?
TruFit's methodology is grounded in over 100 years of personnel selection research, most recently validated by Sackett et al. (2022), the largest meta-analysis of hiring method validity ever conducted. That research confirms structured interviews (.44-.57) and work sample tests (.42-.54) are among the strongest predictors of job performance. TruFit applies these methods specifically to K-12 education, where the stakes are highest and adoption of research-based hiring has been slowest.
What results do districts typically see with evidence-based hiring?
Districts using evidence-based hiring through TruFit have documented a 9.8% reduction in first-year teacher turnover, an 8.4% improvement in early-career teacher effectiveness ratings, and 27% stronger hiring committee confidence in their selection decisions. These outcomes are consistent with the broader research showing that structured, simulation-based assessment methods are significantly more predictive than the resume-and-interview approach used by the vast majority of school districts today.
