Many people think tactful, polite communications is nothing but a lot of hot air, but as Marshall Fock once said, "There is nothing but air in a tire, but is makes riding in a car very smooth and pleasant."
Taekwondo instructors realize that each individual student possesses different natural abilities, such as size, strength, coordination, agility, etc. Once students have developed a proficiency in Taekwondo basics, instructors individualize their training to match their physical and mental capabilities so they may maximize their skills. While working as a part of a team, each student not only develops his or her individual skills, but shares these skills with other team members.
This does not mean there is a weakening of Taekwondo standards. A system of "social promotions" is prevalent in many boards of education and, regrettably, it is also prevalent in many dojangs. Social promotion involves promoting a student to the next level even if the student is not performing at that level. The reasoning is that the student will stay with his/her peers and will not feel like a failure. This is the equivalent of lowering the promotion standards, which weakens the significance of the promotion to the student and to other students who have worked hard enough to meet the original high standards.
