In West Virginia it is not allowed either, here is the rules for our state which probably mirror other states with the same regualtions (they are broken on a daily basis):
? 127-3-7 Out-of-Season Coaching
7.1. Philosophy - Students should have the opportunity to engage voluntarily in school athletic activities provided that the student is eligible, that such activities do not interfere with the students? educational development and the activities do not conflict with the principles of wholesome amateur athletics. The WVSSAC wishes to enhance that opportunity while at the same time discouraging the exploitation of students by overzealous individuals and organizations who attempt to impose an obligation or pressure on the student. There has been growing evidence of commercialism and specialization of secondary school students. Experience has revealed that such occurrences tend to divide the allegiance of students, undermine respect for coaches and officials, and encourage the type of adulation which gives students an exaggerated sense of importance of their own athletic prowess. Rather, athletic participation should be used for the pleasure and satisfaction that is derived from athletic competition in a variety of experiences.
7.2. School organized out-of-season practice or related activities shall only be permitted with principal approval during Weeks 50, 51, and 52 of the National Federation Standardized Calendar. Participation by students must be open to all students, voluntary, and not required directly or indirectly for membership on a school team. Participation by students during these weeks does not meet Practice Rule 127-2-13.4.
7.3. A coach or principal designee of each sport or activity may be present as an observer, lecture participant, staff member, or in any capacity at any summer camp during Weeks 50, 51, and 52 of the National Federation Standardized Calendar.
7.4. A coach or surrogate shall not work with individuals in any form of drills or practice of the coaching assignment except during those dates specified as the season for that specific sport or as designated in Rules 7.2 and 7.3.
7.5. Coaches may participate in a formal development program of the U.S. Olympic Committee (USOC) involving students of the same sport as their coaching assignments. The formal development program must be under the official guidance of the USOC through the National Governing Body (NGB) of the sport. The NGB must assure in writing to the WVSSAC that coaches will receive formal orientation and that strict supervision and monitoring of coaches will ensure that no recruitment or inappropriate influence will be exerted on students.
