League Rules


Each of the private leagues has slightly different rules; it is important that you know the variations. In those cases where teams from two different leagues are playing, go with the home school’s rules. Always make sure that the coaches understand the rules being used before the game begins. If the coaches cannot agree then use NHSF/VHSL rules. 

WCAC (Washington Catholic Athletic Conference) The WCAC uses NHSF rules, no overtime. Bishop Ireton (Alexandria) and Bishop O’Connell (Arlington) play at 4 and 5:45, varsity first. Paul VI (Fairfax) plays at 5 and 6:45, JV first. Paul VI is the only school that plays evening games. All other schools in all leagues play afternoon games.

IAC (Independent Athletic Conference) The IAC (boys only league) uses modified FIFA rules with two 10-minute OT, if needed, not sudden victory. Substitution on throw-ins is by possession team, only, otherwise similar to USSF. We officiate two schools in the IAC, Episcopal and St. Stephens/Agnes (both in Alexandria and close to each other).
MAC (Mid-Atlantic Athletic Conference) The MAC (boys only league) also uses modified FIFA rules with two 10-minute OT, if needed, golden goal. Substitution is the same as for the IAC. We officiate two schools in the MAC, Potomac (Langley) and Flint Hill (Oakton).
ISL (Independent School League) The ISL (girls only league) also uses modified FIFA rules with two 5-minute OT, if needed, not sudden victory. Substitution is WAGS/NCSL style, opponent can sub if team in possession subs. We officiate five schools in the ISL, Episcopal, St Stephens/Agnes, Potomac, Flint Hill, and Madeira (Great Falls).
NVIAC (Northern Virginia Independent Athletic Conference) The NVIAC (boys play in fall, girls in spring) uses NHSF/VHSL rules, with no OT. Some schools use public fields and have constrained playing time. On public fields, coaches may ask for 35-minute halves; otherwise 40-minute. We officiate Fairfax Christian, Christ Chapel (Howison), Fairfax Home Schoolers (South Run), and HEARTS Home Schoolers (Arrowbrook). The NVIAC also runs a Middle School league; 30-minute halves, NHSF/VHSL, no OT. Virginia Academy (Ashburn) is part of the middle school program.
DAC (Delaney Athletic Conference) The DAC uses modified FIFA, no OT. We officiate three DAC schools; Highland (Warrenton), Seton (Valley View), and Trinity Christian (Braddock Road). Highland, Trinity Christian, and Seton also field middle school teams; All may also field JV teams on occasion.
Saint John Paul the Great (Dumfries) Pope John plays a mix of WCAC, NVIAC and DAC teams. Pope John uses modified FiFA with no OT.
Middle Schools
In addition to the middle school programs mentioned above, Flint Hill, Potomac, and St Stephens/Agnes also have such programs. Use modified-FIFA, with no overtime. 30-minute halves.
Prince Williams County (boys in fall, girls in spring). We use NHSF/VHSL for all public school programs, 30-minute halves with 2x5 OT, no sudden victory. The start time is now 5 pm. However, always be prepared to start earlier if the coaches so request. We provide officials for all but three Prince William middle schools.
Arlington County (boys and girls play in fall). As with Prince William, use NHSF/VHSL rules, 25-minute halves with no OT. All games start at 3:15.
Others. We provide officials for Linton Hall (Gainesville), St John Academy (McLean), Langley School (Langley), Holy Family Academy (Manassas), Holy Family Christian School (Manassas), Temple Baptist (Ashburn)  and Aquinas (Tyrell Park). Use NHSF/VHSL rules, no OT, 30-minute halves, except some Langley School games may be 25-minute halves; check with the coaches.
In addition to their regular league affiliations the following schools also participate in VISAA and compete for the state championship:  Bishop Ireton, Bishop O’Connell, Paul VI, Pope John Paul the Great, Flint Hill, Episcopal, St Stephens/Agnes, Potomac School, Highland, Trinity Christian, and Seton (Manassas). Play-in and QF games are played at the higher seed.  SF and Finals are played in Richmond.  The state tournament typically takes place the first two weeks in November.
