The evidence is clear: psychological safety is the strongest known driver of team performance. Learn to measure it, build it, and certify it, with a program grounded in Professor Amy Edmondson's research.
Continuing Coach Education credits included
In 2015, Google's Project Aristotle studied 180 of its own teams. Psychological safety was the single strongest factor in team performance, ahead of talent and experience.
Grounded in Professor Amy Edmondson's research at Harvard Business School, begun in 1999.
Certified TPS practitioners worldwide in the TEAM.AS.ONE community.
Team psychological safety is "a shared belief that the team is safe for interpersonal risk-taking" (Edmondson, 1999). In practice, that means people speak up early, ask for help, surface problems while they are still small, and take the creative risks that innovation requires.
Teams that have it learn faster, retain their people longer, and consistently outperform teams that do not. Teams without it stay quiet, and quiet teams are expensive.
When teams feel safe, they do remarkable things.

Team psychological safety is built, rather than wished for. The TPS model gives you seven observable elements, each one you can assess, benchmark, and develop, resting on five foundations and driving team learning and performance.
Mistakes become learning, rather than blame.
Support without looking incompetent.
Contributions are seen and valued.
Different perspectives are welcomed.
Tensions get addressed, rather than avoided.
Bold ideas without fear of ridicule.
A team that looks out for its own.
Each element is measured by the TPS assessment: a confidential team survey producing a 25-page benchmarked report.

Bring a measurable, evidence-based team development capability in-house, one you can defend to any executive team.
As regulators move toward requiring organizations to assess and manage psychosocial risk and psychological health at work, you gain a defensible, evidence-based way to measure team psychological safety and act on it.
Add a research-backed, assessable team offering to your practice, with ICF CCE credits included.
Diagnose and develop the teams you serve with an instrument, rather than an opinion.

The TPS assessment shows a team where psychological safety is strong and where it is thin. The next question is what to do in the room. The LEGO® Serious Play® method is one of the most practical answers we know.
In a LEGO® Serious Play® session every person builds a model of their answer and every person explains it. The quietest member of the team has the same time and the same attention as the most senior. People speak through what they have built, which makes a hard subject easier to put on the table, and increases the potential level of team psychological safety.
A model gives a team something concrete to point at when a problem has been talked around for months.
Every perspective is on the table at once, built and visible, before anyone has argued for it. It works particularly well for introverted and neurodivergent people: everyone gets time to think before they speak, and the answer is focused on an external model rather than on the individual.
A half-formed idea is easier to offer as a few bricks than as a finished proposal.
And it reaches well beyond psychological safety. Practitioners use LEGO® Serious Play® for:

The program was developed by Peter Cauwelier, PhD, and builds directly on Professor Amy Edmondson's research.
This transformative experience has empowered me to help teams create environments where everyone feels safe to express their thoughts, ideas, and concerns without fear of negative consequences. By participating in this programme, you can expect improved collaboration, increased engagement, and enhanced overall performance within your team.
As a leader, I found the practical strategies, the seven elements and five foundations to be immediately relatable and applicable. I was impressed by the comprehensive, evidence-based approach of the Team Psychological Safety certificate course. This is a must-attend for any leader and HR, L&D who wants to take their team to the next level.
Four sessions of 3.5 hours each: modules 1 and 4 on Zoom, modules 2 and 3 in person in Vancouver, all on Pacific time. Between modules 3 and 4 you work in a small group on a real case and develop an intervention approach, and module 4 is where that comes back. There will be some pre-reading prior to each module.
Not this cohort. Modules 2 and 3 are in the room, so you need to be in Vancouver on the afternoon of Friday, November 20 and the morning of Saturday, November 21. The next cohort runs fully online. Leave your details below and we will send you the dates as soon as they are set.
It connects directly to psychological health at work, and it is a team-level performance construct from organizational research, about interpersonal risk-taking and team learning. You will learn to measure it and connect it to both wellbeing and performance outcomes.
You leave with a licensed capability, rather than only learning: the TPS assessment licence, a benchmarked team report included, a practitioner toolkit you can deploy across teams immediately, and a copy of Peter Cauwelier’s book, Your Untapped Team Advantage Toolbox.
No. The program is designed for HR professionals, wellbeing and safety leaders, coaches, team leaders, and consultants alike. Every element is taught from the ground up.
It is possible to miss one of the Zoom sessions and to watch the video afterwards. However, we ask that you be present for both the in-person sessions on Friday afternoon and Saturday morning.
Yes, and pairs often get the most from it. Two or more people registering together pay the Bring a Buddy rate of CAD $1,100 each.
