Information from validity studies has been collected as long as the test has been in use.
The first set of validity studies was reported in 1957, using scores from 10 schools that admitted students on the basis of the first administrations of the GMAT exam in 1954.
The Validity Study Service (VSS), established in the late 1970s, is available free to any school that uses the GMAT exam. The purpose of the service to offer schools documented proof of the effectiveness of GMAT scores for their unique situation.
More than 1,100 individual studies have been conducted for graduate management programs in over a dozen countries around the world.
Researchers at various schools who have conducted validity studies for different graduate management programs have found results similar to those of studies conducted through the VSS at GMAC. A meta-analyses of more than 400 publicly available studies of the validity of the GMAT estimated the validity of GMAT Total scores alone to be 0.47 (Kuncel, Crede, and Thomas, 2004).
