Is Mastery-Based Learning better than the education conveyor belt?

This question came to mind a couple of weeks ago while I was in the middle of teaching an online class for an educational course on machine learning. The class was beginning to grasp the difference between traditional rule-based statistical models and machine learning probabilistic models. In the middle of the explanation, my mind drifted for a second and landed on this related topic.

What is Mastery-Based Learning?

In mastery-based learning (MBL), students only advance once they have fully mastered the current topic. They don’t move forward with gaps.

I believe it is 2x to 5x more efficient than the “conveyor belt” system, which pushes students ahead based purely on age, regardless of whether they’ve learned the material.

Although I possess all the certificates that prove that my schooling has been traditional and successful, a bigger part of me knows that my true knowledge comes more from the learning I acquired in studying from true masters of their craft, much more than learning the answers needed in an examination.

Challenges of Mastery-Based Learning

MBL demands experienced teachers, flexible schedules, and more resources—things most underfunded schools lack. It also clashes with society’s preference for age-based classes and social cohesion.

Implementing it in traditional schools creates logistical problems: varying student paces disrupt the factory-like structure, leading to disengagement, uneven workloads for teachers, and difficulties in defining “mastery” and grading it fairly.

Aligning students, parents, and administrators adds another layer of difficulty.

Failings of the Traditional Conveyor Belt System

Our current education system is a leftover relic from the British industrial era. It treats students like identical products on an assembly line, prioritising discipline and uniformity over real understanding. It assumes that knowledge is finite and everyone learns at the same pace, leaving some students lost and others bored.

The result? Shallow learning, disengagement, and graduates who lack deep knowledge, creativity, and 21st-century skills like adaptability and problem-solving.

It was designed to produce obedient factory workers, not independent thinkers, and it remains highly successful at that.

A Balanced View

Mastery-based learning clearly produces stronger understanding. However, it creates its own issues. A student who masters material years ahead of peers may struggle to fit into a society still built on the conveyor belt model.

In India’s context, the traditional system still has some value. Large parts of our economy rely on disciplined, standardized labor.

At the same time, our most valuable contributions—especially in IT, services, and innovation—were started by people with real mastery and reasoning skills that serve global economies.

Thinkers and critics have rightly criticised the time-based, one-size-fits-all approach for undermining true learning and stifling creativity.

Mastery-based learning is a better path, but shifting to it requires more than good intentions—it demands practical solutions to the very real logistical and social challenges.

Conclusion

This debate raised a deeper question in my mind: What kind of society do we actually want to build?

Do we want a society filled with disciplined, uniform individuals — all cast from the same mould, where obedience replaces original thought? If your answer is yes, you might be helping India move closer to becoming like North Korea.

Most of us would reject that vision. We’d say such military-style discipline belongs only in the armed forces.

So here’s the real choice:

Do we want a society rich with musicians, artists, poets, scientists, engineers, doctors, technicians, comedians, businessmen, entrepreneurs, singers, and dancers — each one a true master of their craft?

If the answer is yes, then we must move beyond the outdated conveyor-belt education system and wholeheartedly embrace mastery-based learning. Or at the very least, create genuine space for it.

Only then can we build a truly dynamic, innovative, and thriving society.
