Make the Call
Rules training for officials
Free
Make the Call is a rules education and training platform built for sports officials and the associations that develop them.
Officials study the rules the way they actually need them — in plain English, organized the way the rules book is organized, with the rule references you need to find the source. Every lesson ends with scenario questions that test judgment on the field, not memorization.
WHAT YOU GET
• Rules Book — plain-English lessons following the official rule order, with rule-number citations so you can always find the source • Rules Simplified — the fouls and situations officials get wrong most, explained in the language of Friday night • Signals — the high school football signal set, with reference, flashcard, and quiz modes • Power Positions — position-specific study material for crew roles • Weekly Quizzes — short quiz sets to keep the rules current through the season • Progress tracking — your association can see who has studied and who has been tested
BUILT FOR ASSOCIATIONS
Make the Call is licensed by officiating associations, leagues, and schools for their members. Individual officials are never charged inside the app. Your association handles access; you just study.
Association administrators get a member roster, application review, progress reporting, and the ability to publish announcements to their members.
WHO IT IS FOR
Football officials working high school games. Additional sports are in development.
Make the Call is an independent product of Kadazo LLC. It is not affiliated with, endorsed by, or sponsored by the National Federation of State High School Associations or any state association.
