In this chapter the following words are used in the meaning given, unless the context clearly indicates another meaning:

(1) "Disability" is short for the statutory term "the presence of any sensory, mental, or physical disability," except when it appears as part of the full term.

(2) "The presence of a sensory, mental, or physical disability" includes, but is not limited to, circumstances where a sensory, mental, or physical condition:

(a) Is medically cognizable or diagnosable;

(b) Exists as a record or history;

(c) Is perceived to exist whether or not it exists in fact.

A condition is a "sensory, mental, or physical disability" if it is an abnormality and is a reason why the person having the condition did not get or keep the job in question, or was denied equal pay for equal work, or was discriminated against in other terms and conditions of employment, or was denied equal treatment in other areas covered by the statutes. In other words, for enforcement purposes a person will be considered to be disabled by a sensory, mental, or physical condition if he or she is discriminated against because of the condition and the condition is abnormal.

(3) An "able worker with a disability" is a person whose disability does not prevent the proper performance, with or without reasonable accommodation, of the particular job in question.

(4) "'Dog guide' means a dog that is trained for the purpose of guiding blind persons or a dog that is trained for the purpose of assisting hearing impaired persons."

(5) "'Service animal' means an animal that is trained for the purpose of assisting or accommodating a disabled person's sensory, mental, or physical disability."

(6) "Health care professional" means a person whose license to practice includes diagnosis and assessment of the particular disability for which she or he issues a health care opinion.
