Situations where Career Objective may be the most effective to be mentioned on the Resume:

• Career Change: In the case of a career change, it is necessary to state up front the specific career desired and the willingness to take an entry level position
• Specific requirements: Such as location, part-time or internship employment, or a specific position or organizational culture.
• Less than 3 years professional experience: Generally, the alternative to a career or job objective is a professional summary. New graduates or individuals re-entering the work force rarely have enough recent relevant experience for an impactful professional summary.
