When to teach by CEJames & Alfonz Ingram
Ideally, I personally prefer to use the term, "mentoring" over teaching, but the latter is more recognized by the martial community.
Ideally, as to my personal experience, especially in the dojo, along with extensive teaching and instructing as a US Marine having taught for over 10 years young marines for their MOS, I have found a ratio of one instructor or teacher for four people at a minimum.
Going beyond four tends to depend heavily on each individuals abilities, experiences, and background in the art or subject matter being taught.
In order to ensure that mistakes are quickly corrected during the teaching process a good teacher or instructor must monitor closely and correct for best growth and understanding.
The higher the ratio of student to one teacher will have an adverse effect on how well those students learn as the teachers ability to observe and to teach is spread out in relation to time spent teaching the subject matter how well students absorb and understand, etc..
As to a student becoming an assistant, instructor or teacher, they first have to have a solid foundation of knowledge, understanding, experiences, and abilities to communicate in a man or best suitedto a student understanding and absorbing materials.
Now these are my thoughts on teaching, especially in a dojo that focuses on self-defense as self defense in the real world have so many factors involved for correctness, especially if it goes to legal and moral issues requires one to really make sure a student understands and can apply their understanding in a creative way.
What follows Was provided through the various sources seen in the references that will help further guide in making decisions on when a student in the dojo or in any other venue starts to assist a teacher or instructor. After all in a successful dojo students can exceed the 14 ratio quickly and in order to retain studentfor the long haul as it requires to properly teach and learn and practice and apply martial arts, especially in self-defense they must be able to motivate and stimulate a student.

Teaching Ratio
Shidō hiritsu [指導比率]
The optimal teacher-to-student ratio in a martial arts dojo depends on several factors, including the students’ skill levels, the type of training (kata, kumite, self-defense drills), and the instructor’s experience. However, research from educational psychology and martial arts pedagogy provides general guidelines:
1. Ideal Ratios Based on Skill Levels
• Beginner Classes: 1:4 to 1:6
Beginners need close supervision to develop proper fundamentals and avoid ingraining bad habits. A ratio of 1 instructor per 4-6 students allows personalized corrections and guidance.
• Intermediate Classes: 1:4 to 1:8
At this stage, students have foundational fundamental skills and require more partner-based training. Slightly larger ratios can work if students help each other under the instructor’s close supervision.
• Advanced Classes: 1:8 to 1:10+
Advanced students require less direct correction and more autonomy. The instructor focuses on refining techniques and concepts rather than constant monitoring.
Note: at these levels the sensei must refrain from allowing students to assist in training dojo-mates.
2. Considerations for Different Training Methods
• Kata & Forms Training: 1:4 to 1:8
Since movements are performed individually, a higher student count is manageable as long as the instructor can walk around and provide feedback.
• Partner Drills & Self-Defense Scenarios: 1:4 to 1:10
When students work in pairs, the instructor must ensure proper execution and safety, requiring closer supervision.
• Sparring (Kumite/Randori): 1:4 to 1:10
Due to the dynamic and unpredictable nature of sparring, lower ratios allow instructors to maintain safety and give real-time feedback.
Note: at these levels the sensei must refrain from allowing students to assist in training dojo-mates.
3. Educational Research Supporting Small Ratios
Studies in education support smaller class sizes for better learning outcomes:
• Blatchford et al. (2002) found that smaller teacher-to-student ratios significantly improve engagement and individual progress in skill-based learning.
• Hattie (2009) emphasized that immediate feedback is crucial for skill acquisition, which becomes harder with larger student groups.
4. Assistant Instructors to Balance Larger Classes
To maintain quality instruction, dojos with larger classes often:
• Use senior students or assistant instructors to provide additional guidance.
• Break large classes into smaller groups for focused instruction.
Conclusion: Balancing Efficiency and Quality
For optimal learning and safety, the recommended teacher-to-student ratio in a martial arts dojo is:
• Ideal Range: 1:4 to 1:10 for hands-on, technique-focused training.
• Maximum Effective Ratio: 1:10 for experienced students in structured drills.
• Beyond 1:10': Requires assistant instructors or splitting the class into smaller groups for effectiveness.

The Ideal Student-to-Teacher Ratio for Maximum Understanding
The ideal student-to-teacher ratio for martial arts training depends on multiple factors, including cognitive load, the complexity of techniques, feedback requirements, and student engagement. Research in education, skill acquisition, and martial arts pedagogy suggests that lower ratios generally enhance learning, but the exact number varies based on instructional methods and student proficiency levels.
1. Research-Based Optimal Ratio for Skill Acquisition
Studies in education and motor skill learning provide strong evidence that smaller teacher-to-student ratios enhance understanding and skill retention:
• Blatchford et al. (2002) found that students in smaller groups received more direct teacher interaction, leading to greater engagement and comprehension.
• Hattie (2009) in Visible Learning reviewed over 800 meta-analyses and identified immediate feedback as one of the most critical factors for learning, which is more effectively provided in smaller classes.
• Ericsson et al. (1993) on deliberate practice emphasized that focused, personalized feedback is essential for mastering complex skills, supporting the need for a lower student-to-teacher ratio in martial arts.
Key Findings:
• Ratios below 1:8 significantly improve skill acquisition due to more individualized attention.
• Ratios above 1:10 begin to reduce student engagement and feedback effectiveness.
2. Martial Arts-Specific Ratios for Maximum Understanding
The ideal student-to-teacher ratio depends on the type of training:
Training Type Optimal Ratio Reasoning
Beginner Techniques (Kihon, Basics) 1:6
Close supervision prevents bad habits and ensures proper form.
Kata & Forms 1:8 to 1:12
Allows for corrections while maintaining class efficiency.
Partner Drills (Kumite, Self-Defense) 1:6 to 1:8 Ensures safety and immediate feedback during application.
Sparring (Randori, Kumite, Free Practice) 1:4 to 1:6
Requires real-time corrections for safety and strategy development.
Weapons Training 1:4 to 1:8
Requires high supervision due to risk factors.
Supporting Research:
• Wulf et al. (2001) found that motor skill learning improves when feedback is frequent and precise, which is harder to achieve in large classes.
• Lave & Wenger (1991) in Situated Learning emphasized that close student-mentor interaction is essential for skill transmission, which supports lower ratios in martial arts.
3. Cognitive Load and Learning Efficiency
The cognitive load theory (Sweller, 1988) states that humans can only process a limited amount of information at once. Lower student-to-teacher ratios help by:
• Allowing incremental learning without overwhelming students.
• Providing real-time correction to reinforce proper technique.
• Reducing distraction and waiting time, increasing active learning.
Supporting Research:
• Sweller (1988): Lower ratios reduce extraneous cognitive load, making learning more efficient.
• Bandura (1986): Social learning theory states that students benefit from direct observation and modeling, which smaller groups facilitate.
4. The Role of Assistant Instructors in Scaling Learning
In larger dojos, assistant instructors help bridge the gap when ratios exceed the optimal range.
• Head instructor focuses on core principles and assistant instructors.
• Assistants provide individualized correction for beginners.
• Peer learning (Vygotsky, 1978) occurs when experienced students help novices.
Practical Adjustment for Larger Dojos:
Class Size Ideal Teaching Structure
1-10 students
Single instructor (direct feedback possible).
10-20 students
Instructor + 1 assistant for small group corrections.
20-30 students
Instructor + 2-3 assistants, breaking into smaller groups.
30+ students
Instructor oversees, assistants run breakout sessions.
5. Conclusion: The Best Ratio for Maximum Understanding
General Recommendation:
For optimal learning, a student-to-teacher ratio of 1:4 to 1:6 is ideal in martial arts settings, ensuring:
• High engagement.
• Frequent and precise corrections.
• Enhanced retention through individualized feedback.
Maximum Effective Ratio:
• 1:8 for kata and group drills.
• 1:8 for partner training.
• 1:4 to 1:6 for sparring or weapons training.
If exceeding these numbers, assistant instructors or structured small-group sessions are necessary to maintain quality learning.
