The Pareto principle is arguably one of the most widely applied rules in management. It states that:

20% of actions lead to 80% of results. 80% of actions lead to 20% of results.


Now let’s think about what this means in the classroom. Only 20% of the typical teacher’s activity leads to 80% of the student’s learning outcomes. In fact, researchers have found that 20% of the students take up 80% of the time and resources in the classroom.

There are 3 things you need to do to effectively take advantage of the Pareto principle in your school

1. Know your 20%

From preparing lesson plans to conducting the assembly, get your teachers to write a list of their daily task. Next, they should rate each task based on how much impact it has on the student learning outcomes. Here is a free worksheet you can use.

2. Be Minimal

Teachers should be allowed to avoid any activity that does not have a clear purpose. Reward effectiveness rather than activity. E.g. Teachers should not only win prizes for punctuality but also for increasing the average student performance.

3. Allocate Resources

Allocate more time, finance and human resources to your 20%. You can leverage technology to carry out the less impactful tasks so that teachers have more time for the most important 20%.
