FROM MIDDLE ATLANTIC WEBSITE:  An IMX score is only established after a swimmer has swum all of the events required for their age group in a sanctioned meet since the start of the current season; both short and long course seasons start September 1 and end August 31 for IMX purposes.

Additionally, a swimmer must complete all of the events in the same course (SCY or LCM) to have a score in that particular course.

The IMX Challenge is a motivational program whereby swimmers will be scored and ranked nationally [USA National Database] on their performance in a combination of five or six events. The purpose of the program is to promote versatility in age group swimming while advocating greater participation and development across a range of events that are integral to long term success in swimming.

Swimmers will participate in a designated combination of five or six events and, based on the power points scored for each of those swims, earn a combined score that will be called the IMX Score. These combined scores will be ranked by single ages with rankings and recognition available on the USA Swimming website.

Using Hy-Tek’s Single-Year Age Group Power Points, all USA Swimming registered athletes earn an “IMX Score” based on the cumulative point total of the combination of IMX events for their age level. The overall IMX score, as well as the swimmer’s current best score for each IMX event, appears on the athlete’s My USA Swimming page for each season. As times in these events improve, the swimmer’s IMX score is automatically updated.

In order to receive an IMX score, a swimmer must legally swim each IMX event for their age level in a sanctioned meet at least once during the season.
