SUNY campuses are implementing a pool testing strategy based on saliva samples, including Cornell,[49][50] SUNY Fredonia or SUNY Oneonta.[51]

The University of Tennessee[52] is also implementing a saliva pool testing strategy.

Researchers from Yale University,[53] Georgia Augusta University,[54] the University of Illinois,[55][56] are also considering or implementing pool testing strategies.
