An exemption is a rule or law which excepts certain things from another rule or law. For example:
- A grandfather clause , in the modern use of the U.S. term, is an exemption that allows a pre-existing condition to continue, even if such a condition is now prohibited from being begun anew.
- A tax exemption allows a certain amount of income or other value to legally avoid taxation .
- Particularly in the US , an exempt employee is one who is not entitled to overtime pay.
- A student may elect to try for an exemption from a class , if he or she already knows the material from previous work at another school or job . An exemption exam is usually taken by the student as proof of this knowledge.
