The set of "good teacher" is not well-defined because the criteria for what makes a teacher "good" can vary significantly based on individual perspectives, cultural norms, and educational philosophies. Factors such as student outcomes, teaching methods, communication skills, subject knowledge, and personal characteristics all play a role in defining a good teacher. Therefore, what constitutes a good teacher may differ from person to person, making it a subjective and complex concept.
Elements that have to be defined by personal judgement. Such as the set ofgreat songs is not well-defined. But the set of the English alphabet is well-defined.
The description of a well defined set clealy states what is in the set. For example, "deciduous trees" is a set that only includes trees that are deciduous. No conifers or non-deciduous trees are in the set. "Tall trees" is not well defined because the members of the set depends on what "tall" means to different people. Well-defined sets can be illustrated by using pictures of what would be inside and outside a circle to show which would and would not be in the set.

A set is a well defined collection of elements
Any well-defined set of numbers.
A well defined set is one that you know exactly what is meant when you read it. For example, the set of all people 6' 1" tall is well defined. Whenever you meet someone, if they're 6'1" tall, they're in the set. Otherwise, they're not. You know exactly what I mean. So that set is well defined. The set of all cute shoes is not well defined. Jane just adores buckles, so any shoe with a buckle is cute to her. But Martha likes plain shoes. Buckles are big, ugly things that detract from the shoe. So a shoe with a buckle is not cute to Martha. So the set of all cute shoes is not well defined, because you can't just look at it and determine if it belongs in the set. So the set of all buckled shoes would be well defined, but the set of all cute shoes is not.
