Each team has a probability of winning the championship in their division based on the power ratings. The games unplayed are assigned a score based on a random number and the difference in the two teams power rating. Multiple simulations for a season are recalculated and the net result is the championship probability. This probability is an indication of whether a team has any chance of being the best in its division. Please note that the championship probabilities DO NOT align with the laxnumbers power ratings because for this calculation, a modified 'laxpower' power rating was employed. The results between these two power ratings is slight! See more

Power ratings, unlike RPI ratings are not based on Wins and Losses but rather the goal margin of victory versus opponents. The difference between two opponents power ratings is the predicted goal difference if two teams played each other on a neutral site.

High School and college archived data goes back to 2004 and includes Power Ratings, RPI, SOS, schedules, scores, etc. See more

RPI is a measuring parameter used by the NCAA to determine college tournament invitations. It is based on won-loss records and not the score or goal margins of victory. We provide these values for not only colleges but, as a courtesy to our fans, high school as well. We do not recommend using the RPI method to evaluate strength of teams because it ignores the most critical piece of data and that is the game score. As an example: if two teams play identical records and the first team overwhelms its opponents whereas the second team barely defeats it opponents, the RPI calculations has both teams of equal strength. The power ratings, on the otherhand, has the first team of much higher strength than the second based on the goal margin of victories. See more

SOS is a measure of how difficult a team’s schedule is. There are two ways of computing the strength of opponent and the first is based on the opponent’s power ranking and the second is based on the RPI ranking. See more

QWF is a measure of wins and losses based on the opponent’s strength. A victory counts more against a higher ranked opponent than a lower ranked opponent and a loss against a higher ranked opponent counts less than a loss against a lower ranked opponent. There are two ways of computing the strength of an opponent, the first is based on the opponent's power ranking and the second is based on the opponent's RPI ranking. See more

A list of all games played by a team with the score and other attributes such as average goals (offensively, defensively) and performance versus top teams is listed.

Foremost is over-achieved or under-achieved performance for each game played. Each game is examined to determine if a team over- performed (+.++.+++) or under-performed (-,--,---) based on the power ratings of the two teams, home-field advantage and the score.

Archived data from 2004 to present can be found for men, women, boys and girls.

The NCAA evaluates teams for selection to the NCAA Championship Tournament based on RPI, SOS and QWF. We present these parameters and employing a formula that weighs them equally, LaxMath predicts the at-large order of selection for men and women varsity divisions. This applies primarily to college although, for the curious, LaxMath also applies it to high school. See more

Are you a high school recruit (boy or girl) planning to attend college and play lacrosse? If so, we can help you find the colleges that meet your athletic and academic requirements?

Here is how we do it. We break down the 700+ colleges into varsity and club level divisions and we list the SAT admission scores required for each school. Then we include how that school has performed on the lacrosse field based on its lacrosse ranking within that division covering a span of ten or more years. The higher the SAT admission score, the greater the challenge in gaining admissions. The greater the lacrosse ranking, the greater the challenge in making the team and getting playing time.

After just a few minutes, you can come up with a short list for potential candidates and you can further narrow this list based on your research of location, finances, etc. To see this list click here
