Seeds
With the Ivy League choosing not to participate in spring athletics, neither Harvard nor defending conference champion Princeton participated in the season. As a result EIVA changed tournament formats. All six schools participated in the tournament. Seeds 1 and 2 received byes to the semifinals, which were played at Rec Hall in University Park, Pennsylvania. The Championship also was played at Rec Hall. Seed 3 played seed 6, and seed 4 played seed 5 in the conference tournament opening round at the 3 and 4 seeds' schools.

Seedings and placement were to be determined by win percentage should teams not have played every match. Tiebreaker procedures were as follows:
 * Head-to-head match record
 * Head-to-head sets won against each other
 * Head-to-head points amongst the tied teams
 * Sets winning percentage within the conference
 * Points against teams within the conference
 * Coin toss by the EIVA Commissioner
