After the definitions of perfect and semiperfect rings, the transportation of them to perfect and semiperfect modules is a significant creation for new characterizations of supplemented modules and the other modified versions of them. Inspired by this idea, we aim to create a route from δss-perfect rings to δss-perfect modules. A module W is said to be δss-perfect if each factor module is of a projective δss-cover. Owing to this goal, we obtain new relations for projective (amply) δss-supplemented and δss-lifting modules. Also, we present various characterization theorems for a (projective) module to be δss-perfect.
