GRALOA is interested in supporting our officials using best practices.
One valuable resource is the Officials Development Program at US Lacrosse. There are many resources to dig into on the US Lacrosse website from professional development opportunities, to certification, to rules, and much more. Start here: https://www.uslacrosse.org/officials/become-an-official
To officiate lacrosse at the high school level in the State of Michigan one must join the Michigan High School Athletic Association (MHSAA) and remain a Member In Good Standing (MIGS) with a Local Officials Association (LOA).

Most high schools and youth associations that play lacrosse in Michigan and beyond follow rules written by The National Federation of State High School Associations (NFHS). You can find those rules and more here: NFHS Rules
