D.I.R. Floortime (also known as Floortime) is an intervention that is used to promote an individual's development through a respectful, playful, joyful, and engaging process. It uses the power of relationships and human connections to promote engagement, communication, positive behaviors, and thinking. It is based on the DIR® model that was developed by Dr. Stanley Greenspan and his colleagues. It is used around the world by teachers, occupational therapists, speech therapists, mental health professionals, parents, and many others that care for individuals with developmental challenges or other related needs. It is an evidence-based approach to promoting human development that is used with children, young adults, and even adults...especially those on the autism spectrum.

Pronunciation Note

"DIR" is an initialism form of an acronym meaning that each letter is stated rather than pronouncing it as a word. So, "DIR" is pronounced "D" "I" "R". "ICDL" is the same way and each letter is stated rather than pronouncing it as a single word.

With DIRFloortime® professionals in over 50 countries around the world, you can search the DIRectory for professionals from just about anywhere. Search for DIR® professionals, review their listing, and contact them all from one place.
