The Junior Golf Scoreboard system is based on a formula that reviews a player’s record in 36-hole or longer tournaments over the last 365 days. Tournaments drop out of the calculation after one year. A player must have three events within the year to be ranked.

The criteria are as follows:

• Scoring differential: For the 85 percent of the player's rounds that are his/her lowest scores, a player’s average score is compared to the USGA rating of the courses they played (65 percent weight).
• Strength of Field: Whom did the player compete against and how strong were the records of the their competitors (25 percent)?
• Finish: Average finish of the competitor with consideration given to the size of the field (10 percent).
  The Junior Golf Scoreboard typically receives results for over 1,100 tournaments worldwide and ranks approximately 5,000 – 6,000 players at any one time.

The Sagarin system is based on a mathematical formula, using the following categories to determine a rating for each junior who has played in at least four events over a 52-week period:

• Power Rating: The rating is calculated using a player's record, stroke differential and connection to all the other players in the database.
• Schedule Strength: The average strength of each event in which the player has played, calculated using the power ratings of every player in every field.
• Schedule Rank: The player's schedule is ranked by difficulty among the entire database
• Records: A player's won-lost-tied record, based on head-to-head competition, in each category. The winner in a 156-player field has a record of 155-0-0, the runner-up is 154-1-0, etc.
