What Is Longitudinal Assessment?

Longitudinal assessment is a method proven to help ensure continuous acquisition of knowledge. It works by administering shorter assessments of specific content repeatedly over a period of time to help individuals increase their understanding, knowledge, and skills toward achieving the performance/practice standards in a specialty.

During the time interval individuals are taking the assessments, they will get regular feedback about where they are according to the performance standard. They will get information that identifies where they are, how their performance compares to their peers, and the gaps between their performance and what successful performance looks like. With access to suggested resources for learning, and repeating the assessments, individuals can increase their knowledge and demonstrate that they are keeping up with the information in their field.

A variety of studies and literature support longitudinal assessment. Studies focused on medical professionals include a study published in Patient Safety & Quality Healthcare that found in more than 16 randomized trials, physicians improved long-term knowledge retention by answering questions over spaced intervals of time. Another study of medical students published in Medical Education found that testing in combination with explaining the information is the most effective way to drive long-term retention of information. The American Board of Anesthesiology, which offers a longitudinal assessment approach called the MOCA Minute®, found that Board Certified anesthesiologists who participated in the MOCA Minute outperformed non-participants on the Maintenance of Certification in Anesthesiology (MOCA) Cognitive Examination, according to a study published in Anesthesiology.
