A test has correct answers, while an assessment measures degrees of competence, according to Ryann K. Ellis in How Workplace Assessments Can Help You from the Association of Talent Development (formerly ASTD) on May 3, 2016.  For example, Lesson-Up’s online Practice eQuiz has multiple-choice test items which have correct choices.  The  Comprehensive Performance Examination is an assessment in that it consists of challenges requiring problem solving, synthesizing, creativity,  demonstration of skill performance, and application of the concepts to a career/ occupation of choice.
