Last fall, the NCAA, NFHS and US Lacrosse announced new and simplified stick stringing specifications for women’s collegiate, high school, and girls’ youth play, effective for the 2018 season.  

In response to recent inquiries, US Lacrosse today issued clarifications to the new requirements. These are not rulebook edits, but rather information intended to provide further guidance for compliance to Rule 2 and Appendix B of the USL/NFHS Girls’ Lacrosse Rule Book. US Lacrosse writes the rules for high school girls’ lacrosse, and those rules are endorsed by the National Federation of State High School Associations (NFHS).

“We are excited about the interest that groups are showing for the new stick specifications, and we believe that the changes will be a catalyst for innovation and growth in the women’s game,” said Caitlin Kelley, women’s game senior manager at US Lacrosse. “In the first year of these new changes, we are all working together to ensure that manufacturers, officials, coaches, players and consumers are on the same page in regards to compliance and intent of the specifications.”

Among the clarifications, noted in italics:

Section 20:
The stipulation for 0.3 cm maximum nominal diameter for pocket nylon is a manufacturer’s specification. Officials shall not measure this for compliance as part of their routine stick checks.

Technical criteria assume a defined gap is present between pocket nylon mesh. A solid surface of nylon would be non-compliant.  

Section 21:
The allowance of coils for the shooting strings remains the same for a traditional pocket, no more than two coils or twists between thongs. In a mesh pocket, the allowance is one coil per diamond of mesh

Section 22: 
The shooting string requirements remain unchanged. If a stick has only one shooting string, it must be within 3.5 inches from the top of the head.  

Further clarifications, including information about ball movement as defined in Section 25, are outlined in the document provided by US Lacrosse. The ball movement test shall be performed in the same manner as in the beginning of the 2018 Rules Video, which can be accessed online at

Both the clarification document provided by US Lacrosse and the NCAA’s stick rules document also provide photos to further support the explanations.
