The Training School At Vineland was started by Reverend S. Olin Garrison from Millville. In 1887 he started the training of feeble minded children in Millville, but soon there was need for a larger facility. This was provided in Vineland by he Board of Trade and a philanthropist by the name of B. D. Maxham. Over the years the institute became world famous for it's work on mental testing and the study of human behavior.

The professionals at the Training School in Vineland promulgated their ideals all over America and ultimately they became accepted in most of the world. Because of this, the institute was truly world famous.

The Binet scale was developed at this institute, the Kallikak Study was conducted here and the Vineland Social Maturity Scale led to the concept of adaptive behavior.

At present, the students live in homes in the community and come to the center during the day for education and programs.
