Abstract - Progresses in the development of a free-fall test of the Principle of Equivalence (PE) are reported with particular emphasis on the work related to development of the differential accelerometer prototype and its laboratory tests. The PE experiment is planned to be carried out in free-fall conditions, inside a capsule (Einstein elevator) released from a stratospheric balloon. The accuracy goal for the experiment is a few parts in 10^15 with an integration time of about 25 s. This accuracy, if reached, would imply an improvement of two orders of magnitude in testing the PE with respect to the state of the art in this field.
