Paragon Learning Style Inventory or PLSI refers to a self -administered survey that provides a very reliable indication of learning style and cognitive preference. It uses the four (4) Jungian dimensions (i.e, introversion/ extroversion, intuition/sensation, thinking/feeling, and judging/perceiving) that are also used by the Myers-Briggs Type Indicator, Murphy Meisgeir Type Indicator, and the Keirsey-Bates Temperament Sorter. But this is the only instrument that can be self-scored and works with ages 9-adult. The Paragon Learning Style Inventory is a 52-item learning style inventory that can be self-scored and obtains a measure of the 4 Jungian psychological/learning dimensions. It is written for ages 8 and older. It was last revised in 2003 and is being used around the world by schools, businesses and individuals.
