A practical test, or checkrie is the most common name for part of a Federal Aviation Administration examination which one must undergo in the United States to receive an aircraft pilot's certification, or an endorsement for additional flight privileges. The name refers to the portion of the examination in which the candidate being examined flies in an aircraft with the Designated Pilot Examiner to demonstrate competency in the skills that are required for the certification. Although 'checkride' is the most commonly used term, it is considered informal and is technically known as a Practical Test by the FAA and in all its literature, and the specific objectives which the candidate must meet are called the Practical Test Standards, or PTS. In addition to successfully completing a checkride, one must also complete an oral examination (which happens before, and often to some extent, during the checkride), and meet certain basic aeronautical experience requirements (such as number of hours flown) as well as pass a separate multiple-choice computer-administered test that is quite consistently called the "written test", even though it involves no writing at all.
