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

Round Robin

Determining a

Team with the most points wins.

Ties

you need a process to decide on ties
at the end of your schedule

-
to
-
points for and against, etc…

Elimination

Teams are eliminated from the competition after
one or more losses

Emphasizes winning

Doesn’t take as much time

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

Games cannot end in a tie

Ex. NHL Play
-
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

Winner of Losers Bracket can still win the
tournament.
