Scheduling Session

Factors to Consider


Availability of space


Facility (size and suitability)


Sport (length of games)


Participant conflicts


Nature of competition (recreational or
competitive)

Selecting a Format

Basic formats

1.
Round Robin

2.
Elimination

3.
Combination

The main difference between the two formats is the number
of guaranteed games that teams will play. Therefore, it is
important to decide on the nature of the tournament and
whether you want to emphasize participation or competition.

Round Robin

Ideally, all teams play each other at least once.


Ensures all teams play the same number of
games


For large leagues, pools are often used


Need more time for this format


Better
for teams with less skill just looking to
have
fun

to
-
head results, fairplay points,
points for and against, etc…

Elimination

Teams are eliminated from the competition after
one or more losses

Better
for teams with a high level of skill
looking for a competitive
format


Games cannot end in a tie

-
offs

Byes

Byes occur when there are an odd number of teams


More difficult when scheduling elimination
tournaments


Get rid of all byes in the first round


Number of participants (real or implied) needs to be
a perfect power of 2 (2, 4, 8, 16)

Equal Total: Rank of teams is ______.

Formula: ___________ (where N=number of teams)

Equal Difference: Rank of teams is
_________ or all rankings are similar

Formula: ___________ (where N=number of teams)

Combination

Use a combination of both Round Robin and
Elimination in the same schedule


Preliminary rounds are often Round
Robin (often include pools) and playoffs
are Elimination


Ex. MacEwan Rec leagues and
tournaments

Double Elimination
Tournament


Quicker tournament with more games

per team


Each team must lose twice before they

are out


Made up of a winners bracket and a losers
bracket
