Unwelcome conduct by an individual(s) that is sufficiently severe or
pervasive that it alters the conditions of education or employment and creates an environment
that a reasonable person would find intimidating, hostile or offensive. The determination of
whether an environment is “hostile” must be based on all of the circumstances. These
circumstances could include the frequency of the conduct, its severity, and whether it is
threatening or humiliating. Simple teasing, offhand comments and isolated incidents (unless
extremely serious) will not amount to abusive conduct.
