Not necessarily. Because Title I is about employment, a person must meet the definition of disability and must also be qualified for the job. There are two components to being qualified. First, you need to have the skill, experience, education, and other job-related requirements for the position. For example, it’s legal for an employer to require that a person applying for the job of a foreign language translator be able to translate a foreign language.
The other component of being qualified, in terms of employment, is that you must be able to perform the essential functions of the job, with or without reasonable accommodation. In other words, getting a reasonable accommodation could make you qualified for the job. For example, a person who is deaf may be qualified to the perform the essential functions of a customer service representative once s/he receives the opportunity to use a video relay service and specialized computer software as a reasonable accommodation.
