Every teacher needs feedback. In 2013. In 2026, which is just about to begin. Always

In 2013, Bill Gates gave a TED Talk that, more than a decade later, feels strikingly relevant. In “Every teacher needs feedback”, Gates puts forward an idea that is as simple as it is powerful: no one improves without useful, frequent, practice-oriented feedback. Not elite athletes. Not musicians. And certainly not teachers.

And yet, for years — and still today in many education systems — teachers have been one of the professional groups receiving the least systematic feedback to improve their work, despite carrying out one of the most complex and socially critical tasks there is.

“If all my coach ever told me was ‘satisfactory,’ I’d have no chance to improve,” Gates says.

A paradox we still carry

The paradox Gates highlighted in 2013 is still with us:

• Education systems that demand more and more from teachers
• Students with increasingly diverse needs
• Accelerated curricular, technological, and social change

…yet without solid structures for professional support, peer learning, and formative feedback focused on real classroom practice.

The data Gates cites is revealing: the highest-performing education systems do not focus on controlling teachers, but on helping them continuously improve. Peer observation, analysis of practice, professional learning communities, protected time for reflection… Nothing especially sophisticated. But deeply intentional.

Seeing practice in order to transform it

One of the most powerful aspects of the talk is the use of classroom video as a professional development tool — not as a surveillance mechanism, but as a professional mirror:

• It contrasts subjective perception with reality
• It enables concrete pedagogical conversations
• It makes the invisible aspects of teaching visible
• It generates both individual and collective learning

As one of the teachers in the video says:

“There are things you can’t convey in a lesson plan, a standard, or a pedagogy book. Video makes them visible.”

Today, with the technology available, this is no longer a technical problem. It is a matter of professional culture, educational leadership models, and system-level priorities.

Feedback is not evaluation. It is professional development

Another key message — especially relevant today — is that feedback is not the same as punitive evaluation. Transformative feedback:

• Is frequent and specific
• Is grounded in real evidence from practice
• Is oriented toward improvement, not judgment
• Provides concrete resources to move forward

Investing in teacher feedback systems, Gates argued, would cost less than 2% of the annual teacher salary budget. The cost of not doing so, however, is enormous: professional demotivation, burnout, attrition from the profession, and — above all — lost learning opportunities for students.

An essential reflection in the midst of an education crisis

In a context of global educational crisis, growing scrutiny of the teaching profession, and the search for “quick fixes,” this TED Talk reminds us of something essential:

The quality of an education system cannot exceed the quality of the professional development it offers its teachers.

We do not need individual heroes in classrooms. We need systems that help every teacher become a little better than yesterday — supported, recognized, and professionally cared for.

More than ten years later, the question is not whether the message still holds true.
The question is: how much longer can we afford not to act on it?

It is precisely from this conviction that TeachersPRO was born: an advanced tool that brings together three levels of feedback on professional practice — AI-supported self-analysis with mentoring, peer learning, and data-informed expert feedback — to ensure continuous, meaningful teacher professional development focused on real improvement in teaching.
