Koro-Sensei listens to His Students
One thing that many teachers lack is the understanding that students are also complex human beings, with issues and problems both at home and at school. Koro-Sensei, on the other hand, is the embodiment of empathy and understanding, which is ironic considering he’s an octopus-like monster.
Be it low gradesor some personal issues troubling their lives, Koro-Sensei always lent an ear, along with finding possible solutions to keep his students' worries at bay. From dealing with Nagisa Shota’s toxic mother to counseling Rio Nakamura towards her goal of becoming a foreign diplomat, Koro-Sensei has played a tremendous role in shaping his students' future simply by listening to them.

While some may beg to differ, being a teacher essentially means being there for students and guiding them through life’s bitter strife – and Koro-Sensei does just that. This is also one of the reasons why he was so beloved by his students, as he had left a long-lasting impression on their lives.
All Students Are Equal
It’s an age-old adage thatteachers always have a favorite, whether intentionally or not. Koro-Sensei, however, defies this notion as he clearly proves throughout the anime that all of his students are equal to him. To Koro-Sensei, it doesn’t matter whether a particular student is a high-achiever or extremely skilled, as his only goal is to ensure all of his students succeed in whatever they do.

Many fans might state that Nagisa gets preferential treatment by their teacher, but this statement can easily be debunked as every single student from class 3-E has a moment where Koro-Sensei tries to get them through whatever problem they’re facing. From helping Tomohito Suginoimprove his baseball skillsto helping Manami Okuda in perfecting her poisons, the 3-E homeroom teacher has never once discriminated between his students, and his dedication to improve each one of his students is a testament to his superior teaching abilities.
Keeping Things Fun and Interesting
School isn’t supposed to be simply textbooks and exams, as there’s a lot more to this concept of education that can make things fun and interesting for students.Koro-Sensei does exactly this, making his classroom more intriguing by linking his study lessons with everyday life. He also promotes activities and breaks during classes, as this can keep students immersed and engaged for much longer.
The field trips arranged by Koro-Sensei also play a similar role, as there’s always a hidden lesson for the students behind every challenge. The drastic improvement in his student’s grades and self-esteem are a testament to how efficient this method of teaching can be.

Focus On Each Student’s Unique Talent
Unlike real-life school teachersthat expect every student to perform and work the same way, Koro-Sensei understands that each student is unique, having distinctive strengths and weaknesses that allow them to thrive in different fields. Instead of taking a generic approach to teaching his students, Koro-Sensei modifies his lessons to assimilate all of his students and cater to their respective strengths.
This is evident from his career advice and teaching methods that are tailored towards every student. He even gives special attention to students that lag behind the rest by changing his teaching methods to better suit the student’s learning style. This altruistic quality, along with several others that he possesses, allow Koro-Sensei to stand out as one of the greatest teachers out there.
