Idaho Rules of Evidence

(a)  By reputation or opinion. When evidence of a person’s character or character trait is admissible, it may be proved by testimony about the person’s reputation or by testimony in the form of an opinion. On cross-examination of the character witness, the court may allow an inquiry into relevant specific instances of the person’s conduct.

    

(b)  By Specific Instances of Conduct. When a person’s character or character trait is an essential element of a charge, claim, or defense, the character or trait may also be proved by relevant specific instances of the person's conduct.
