Animals are used in teaching
Animals used for educational purposes are not being used to discover, prove or develop new ideas or techniques, but rather to demonstrate principles and facts which are already well-known. Therefore, when applying the Three Rs to the use of animals in teaching, efforts should focus first on finding a replacement alternative.
When no replacement teaching alternative is available, justification is required to use animals. The level and type of training of the students (graduate/postgraduate, specialized/non-specialized) are important factors.
Painful experiments or multiple invasive procedures on an individual animal, conducted solely for the instruction of students in the classroom, or for the demonstration of established scientific knowledge, cannot be justified.
