i wish to know the best training practices for referees and how to best judge whether in line with the last but one defender
USSF answer (August 17, 2009):
Think of referee training as similar to the musician who wants to get to Carnegie Hall — practice, practice, practice. The best practice is “guided” and so the answer is to hook up with an experienced, reliable referee who can provide quick feedback.
A brief guide can be found in the U. S. Soccer Federation’s “Guide to Procedures for Referees, Assistant Referees, and Fourth Officials.” This book is available from the U. S. Soccer Shop or from your state referee authorities.
