Thompson & Assoc. has been actively involved since 1983 in field studies to identify the causes and to reduce children's injuries at play-sites. The results of these studies form the basis for the programs we offer. Our reseach findings include:

- Pivotal five year study on the causes of injury for 600 elementary children.

Results Showed 70% of injuries are reduced by adequate supervision.

Design Standards not being met account for 25% of play-site injuries.

- Statewide Injury Prevention Project for CDC found Washington State playgrounds averaged 1.5 inches of surfacing but equipment exceeded 6 feet in height.

Results of 15 schools' injury reporting showed play-sites accounted for 73% of elementary school injuries and younger children were injured more often on equipment than older children.

Equipment design and selection may be a key to reducing younger children's injuries.
