The first rankings of the 2017-18 season for ACHA Men's Division 3 were released on November 8th, and for the first time, the teams are sorted solely off of computer rankings.

Four CHE teams have captured spots inside the Top 15 of the Atlantic Region: Cal U of PA (#5), Pitt-Johnstown (#7), Fredonia State (#9), and Penn State Behrend (#14).  The complete Atlantic Region rankings from the first ACHA M3 rankings period are listed below.  With the implementation of computerized rankings, there is expected to be a new rankings released after each weekend of games, culminating with the final rankings period of games played through February 11, 2018.

The Top 2 seeds in the Atlantic earn a trip to the ACHA Men's Division 3 National Tournament in March, held again in Columbus, OH.  The next 8 teams advance to the Atlantic Regional Tournament on February 23-24, where two more teams will earn their way to Nationals.
