The Improvement Plate, first established in 1986, and renamed The Fritz Weidergott Improvement Trophy in 1997 in honor of longtime St. Mark’s soccer coach and leader in the ISL Fritz Weidergott, is awarded to that team which improves its standing in the league by the most number of points from one season to the next. In the case of a tie the team that finished lower in the previous year is declared the winner.
