Psychological Safety Score Calculator
Psychological safety is the shared belief that a team environment is safe for interpersonal risk-taking. Pioneering research by Harvard Business School professor Amy Edmondson, first published in Administrative Science Quarterly (1999) and confirmed by Google's Project Aristotle study, shows that psychological safety is the most powerful predictor of team performance, innovation, learning and wellbeing. This calculator uses items directly inspired by Edmondson's validated 7-item Psychological Safety Scale. Rate each item from 1 (Strongly disagree) to 7 (Strongly agree). This is a screening tool for individual or team reflection.
Screening tool for team or individual reflection. Not a clinical instrument. Items marked (R) are reverse scored.

Psychological safety score formula
Positive items (PS2, PS4, PS6, PS7): score as entered (1-7)
Reverse items (PS1, PS3, PS5): score = (8 - raw score)
Raw Total = sum of all 7 scored items (max 49, min 7)
PS Score = (Raw Total - 7) / 42 * 100
The scoring methodology follows Edmondson's original Psychological Safety Scale (1999). Reverse scoring ensures that all items contribute to safety in the same direction. The 0-100 normalization maps the minimum raw score (7) to 0 and the maximum (49) to 100.
Interpreting your score
- 75-100 (High): Strong psychological safety. Team members feel free to speak up, take risks and admit mistakes. This is associated with the highest performance outcomes in Edmondson's research.
- 50-74 (Moderate): Some safety present but significant room to improve. Identify which items score lowest and target specific behaviors.
- Below 50 (Low): Low psychological safety. Candor, learning and risk-taking are suppressed. Leader behavior change and explicit team agreements on norms are needed.
Psychological safety calculator: frequently asked questions
What is psychological safety?
Psychological safety is the shared belief among team members that the environment is safe for interpersonal risk-taking. It was conceptualized by Harvard Business School professor Amy Edmondson and validated through decades of research across industries. Psychologically safe teams are more likely to voice concerns, admit mistakes, ask questions and propose new ideas without fear of humiliation or retaliation.
Why does psychological safety matter for organizations?
Google's Project Aristotle (2012-2016), one of the largest team effectiveness studies ever conducted, found that psychological safety was the single most important predictor of high-performing teams, outweighing skills, intelligence or experience. Amy Edmondson's research, published in the Administrative Science Quarterly and referenced by the NIH, also links psychological safety to better patient safety outcomes in healthcare settings.
What does the Psychological Safety Scale measure?
Amy Edmondson's original 7-item Psychological Safety Scale measures: whether it is safe to take risks, whether team members can bring up problems, whether team members are rejected for being different, whether it is safe to raise difficult topics, whether it is difficult to ask others for help, whether team members undermine each other, and whether skills and talents are valued.
Can psychological safety be built?
Yes. Edmondson's research and subsequent studies identify three key leader behaviors that build psychological safety: being accessible and approachable, explicitly acknowledging fallibility and the value of input ('I don't have all the answers'), and modeling curiosity by asking good questions rather than providing all answers. Training managers in these behaviors has documented effects on team safety scores.
Is psychological safety the same as being nice or avoiding conflict?
No. Edmondson explicitly distinguishes psychological safety from niceness or complacency. Psychologically safe teams engage in productive conflict and honest challenge because members feel safe enough to disagree and raise concerns. The goal is candor and learning, not comfort. In fact, avoiding difficult conversations is a sign of low psychological safety, not high.
